First Graphene's Chief Technology Officer, Dr Andy Goodwin made a presentation at the Graphene Automotive 2019 conference and exhibition in Detroit on 4th and 5th March 2019. Andy was also invited to chair Day 1 of the conference.
First Graphene provided an update on the measures that have been implemented to ensure the batch to batch quality of PureGRAPH™ products manufactured at Henderson, Western Australia. The Company also presented the latest information on the fundamental properties of PureGRAPH™ products underlining these are righty called graphene materials and also contained an update of progress in key applications.
The new fundamental data indicates PureGRAPH™ is a low-defect, high aspect ratio graphene product with low metal and silicon contaminations levels. PureGRAPH™ has been shown by microscopy to contain high levels of Few Layer Graphene platelets. Raman analysis indicates the average platelet thickness is < 10 layers.
One of the impediments to a more rapid commercialisation of graphene has been the inconsistency of quality material available for purchase. While many organisations state they can produce graphene, buyers have had issues with quality. Recognising this issue, FGR has gone to considerable lengths to ensure a high-quality product fit for delivery to industry.
"We continue to implement testing and monitoring tools that ensure the quality of PureGRAPH™ products for our customers” said Craig McGuckin, Managing Director First Graphene Ltd. “we will also continue to publish the more fundamental information on our products as this information becomes available from our ongoing collaborations with leading universities”.
Like many advanced materials, there is a significant learning curve to advance promising lab results into real commercial products. This includes a learning experience from the manufacturer, for cost-effective high-volume production, and a learning experience for the end-user, to establish the value and utilization of this novel material.
IDTechEx have been following the graphene market throughout this learning experience, and the 13th edition of their commercially focussed B2B graphene conference, Graphene & 2D Materials, will be held from 10 - 11 April 2019 in Berlin, Germany.
Once again, The Graphene Council will be there to help educate stakeholders on the value that graphene enhanced materials deliver, as well as to publicly announce the launch of the Verified Graphene Producer program.
During the previous 12 conferences, the attendees have heard from all the main market players and end-users, with key market announcements made and technical insights provided. As the market reaches a turning point, this becomes more significant as the headlines have greater global impact.
This combined conference and exhibition stands at a crucial point in the history of the graphene market. As laid out in a previous article, attendees will hear many relevant talks including those from: BASF, Sixth Element, NanoXplore, Avanzare, Sixonia Tech, Mitsubishi Electric, Samsung, First Graphene, and many more.
Below are some selected indicators that the hype is turning to commercial reality for graphene. This includes the breaking of the scale vs orders dilemma, notable use-cases as a heat spreader, polymer additive, corrosion resistant coating, or enhanced battery electrode, and the upturn in investment and acquisitions. The specific news and outcomes for these indicators have all been seen at this world leading conference series and will continue to be added into the 2019 events.
2D materials are a diverse family, the event will include presentations on graphene nanoplatelets, graphene oxide (GO), reduced graphene oxide (rGO), and CVD graphene films. This includes perspectives and advancements multiple sections of the current and future supply chain:
Material manufacturing: Attendees will hear from both established manufacturers looking to scale-up proceedings and new entries. For example, this includes NanoXplore and their 10,000 tpa plant announcement and Sixonia Tech a German university spin-out company working on electrochemical exfoliation.
Intermediary formation: suspensions, polymer masterbatches and more are the most useful form of graphene-based products for many end-users. Attendees will hear more about this important step throughout the presentations. For example, Avanzare will discuss masterbatches for the polymer composite industry and Sixth Element provide suspensions to form heat spreaders and coatings.
Integration and end-use application: How the materials are used, and the potential applications are very diverse. The conference will cover this in many applications from the use in energy storage, to polymer additives, electronic devices, thermal interface materials, and more all in discussion.
Material sourcing and market opportunities: Many graphite mining companies are moving downstream and investing heavily to make this market a success. First Graphene are one such example of a vertically integrated company that will be presenting. Similarly, large materials companies are partnering or positioning themselves to utilise graphene products. Delegates will hear detailed analysis and perspectives of this industry from numerous speakers including from the likes of BASF.

Updated: Friday, October 26, 2018
On 26 October 2018 we reported that the advanced materials company, First Graphene Ltd (“FGR”) (ASX: FGR) released an update on the use of its PureGRAPH™ products in the mining services sector.
FGR has now followed up with a confirmed purchase order for 2,000 kg of their PureGRAPH™ material to be delivered during 2019, for use in the Armour-GRAPH™ product range in a mining equipment application.
The purchase order for 2,000kg of PureGRAPH™ range products from newGen for delivery during 2019, represents a significant development not only for FGR, but also for the broader graphene market. It demonstrates the initial market appetite for high quality bulk graphene products of the type in which FGR specialises. Up until now the graphene sector has been supplying mostly samples for evaluation. This order represents a step change in the business as it starts to scale up for larger size orders.
Pleasingly, the premium price to be received pursuant to the order debunks the myth that graphene is expensive. The productivity benefits and material performance improvements experienced when PureGRAPHTM is added to materials more than compensate for the cost of the graphene, and it underpins the pricing strategy employed by First Graphene.
As previously reported (see article below) FGR is working closely with newGen Group to provide performance enhancement to their existing products with the addition of PureGRAPH™ graphene products. newGen Group has recently introduced a branded Amour-GRAPH™ product range of wear liners for bucket wheel, pipe spools and conveyor heavy equipment applications.
In a recent development, the Company was pleased to confirm further progress in its R&D collaboration with newGen Group. newGen is supplying a wear lining system for dryer chute applications to a large Australian cement producer in their Perth facility. It is a leading supplier of cement and lime to the Western Australia’s mining, agriculture and construction industries.
Each 50m2 liner will contain 10 to 12kg of PureGRAPH™ and is a further significant step in the adoption of First Graphene products into large industrial applications. PureGRAPH™ has been demonstrated to provide up to 37% improved tensile strength and improve abrasion resistance by 100% to 500% in high performance polyurethanes.
newGen has now issued a purchase order for 2,000kg (2 tonnes) of PureGRAPHTM to be drawn down as it wins tenders during 2019. There is one final regulatory approval required before the first sale is effected, being the registration of graphene by the National Industrial Chemicals Notification and Assessment Scheme (NICNAS) in Australia.
Similarly, the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) needs to be completed for sales in the European Union. These registration processes are currently underway and they are not expected to provide any meaningful delays.
The National Industrial Chemicals Notification and Assessment Scheme (NICNAS) registration process is required for all chemicals used in industry in Australia. Within the European Union REACH registration is required if an organisation plans to sell greater than one tonne of a chemical within the EU or United Kingdom. First Graphene Ltd has already joined the consortium which is registering graphene as a new chemical. The consortium consists of three graphene organisations, one from China, one from Canada and one European producer.
Managing Director, Craig McGuckin, stated: “We said that we were the world’s leading graphene company, and we are now proving it with this sales order – the start of many. We do not believe there is another company which could deliver both the volume and the consistent quality this order requires. We are now entering an exciting growth phase as industries all around the world are starting to look at ways in which they can use graphene to improve their products and lower their operating costs”.
newGen Managing Director, Ben Walker stated: “My Company has had considerable interest generated for our new Armour-GRAPH™ range since we started developing PureGRAPH enhanced products with First Graphene. The graphene enhanced resin was added seamlessly into our mixing procedure. It is not labour intensive or complicated with regard to our standard operating practices.”
ORIGINAL ARTICLE - 26 OCT 2018
FGR is working closely with a number of companies to demonstrate performance enhancement of their products through the addition of its PureGRAPH™ graphene products. In this case, the wear-life of mining equipment can be extended with the inclusion of PureGRAPH™ graphene into protective polymer linings.
The rapid progress made with these polymer linings was enabled by the high consistency of PureGRAPH™ products and the ease of dispersion into the polymer resin. The know-how being acquired is readily transferable to a vast range of other polymer products, in many industries. The suitability of the PureGRAPH™ is particularly pleasing as it confirms this is a commercially superior product.
It is expected that, as manufacturing companies start to witness the improvements that graphene can offer, there will be an acceleration of demand for supplies of PureGRAPH™. First Graphene is well-positioned to satisfy the demand as it enters an exciting growth phase.
PureGRAPH™ graphene has been successfully incorporated into a high volume application in the mining sector.
A full scale mining reclaimer bucket was cast for an on-site trial with a multi-national mining company
Test work has confirmed PureGRAPH™ readily disperses into the polymer resin used
Further bucket linings will be cast and sold for use in northern Australia with a multi-national mining group
PureGRAPH™ enhanced polymer liners for a range of associated applications will also be trialled
This success with a graphene-enhanced bucket lining will open an important growth curve for graphene enhanced rubbers and composites
There are 12 buckets on the wheel for the machine these buckets are destined for, each with a capacity is 2.2 m3. The reclaimer has a nominal machine capacity is 12,000 tph and maximum capacity is 14,500 tph in bauxite.
As announced in June 2018 FGR is working with newGen Group on equipment used in the mining industry to improve polyurethane liners to protect them from excessive abrasion and increase their useful life.
Since then FGR and newGen have conducted various tests using PureGRAPH™ in polyurethane to determine the best suited PureGRAPH™ product and the optimum quantity to be added. These tests have demonstrated that the PureGRAPH™ product provides significantly increased flexural strength to the base polyurethane product.
newGen have now cast a liner for a Sandvik reclaimer bucket using PureGRAPH™ 20 and are now working with FGR on the use of a PureGRAPH™ enhance polyurethane in other high volume mining applications in the iron ore industry where newGen are preferred supplier.
FGR Managing Director, Craig McGuckin, stated: “Achieving the creation of this bucket liner for a multi-national end user is a credit to Ben’s foresight and the team at FGR.”
newGen’s Ben Walker stated:“We are pleased to be at the forefront of graphene use in mining materials. It has been excellent to work with the calibre of people at First Graphene in this march towards supplying our valued clients with ground breaking, high performance materials.”
About First Graphene Ltd (ASX: FGR)

The Company has collaboration arrangements with four universities and is at the cutting edge of graphene and 2D related material developments. Most recently First Graphene has become a Tier 1 participant in the Graphene Engineering and Innovation Centre (GEIC) of the University of Manchester. First Graphene is working with numerous industry partners for the commercialisation of graphene and is building a sales book with these industry partners.
PureGRAPH™ Range of Products
The PureGRAPH™ range of products were released by FGR in September 2018, in conjunction with a detailed Product Information Sheet. PureGRAPH™ graphene powders are available with lateral platelet sizes of 20μm, 10μm and 5μm. The products are characterised by their low defect level and high aspect ratio.
Graphene, the well-publicised and now famous two-dimensional carbon allotrope, is as versatile a material as any discovered on Earth. Its amazing properties as the lightest and strongest material, compared with its ability to conduct heat and electricity better than anything else, means it can be integrated into a huge number of applications. Initially this will mean graphene is used to help improve the performance and efficiency of current materials and substances, but in the future, it will also be developed in conjunction with other two-dimensional (2D) crystals to create some even more amazing compounds to suit an even wider range of applications.
One area of research which is being very highly studied is energy storage. Currently, scientists are working on enhancing the capabilities of lithium ion batteries (by incorporating graphene as an anode) to offer much higher storage capacities with much better longevity and charge rate. Also, graphene is being studied and developed to be used in the manufacture of supercapacitors which can be charged very quickly, yet also be able to store a large amount of electricity.
Advanced materials company, First Graphene Limited (“FGR” or “the Company”) (ASX: FGR) is pleased to announce the launch of its 50%-owned associate company, 2D Fluidics Pty Ltd, in collaboration with Flinders University’s newly named Flinders Institute for NanoScale Science and Technology.
The initial objective of 2D Fluidics will be the commercialisation of the Vortex Fluidic Device (VFD), invented by the Flinders Institute for NanoScale Science and Technology’s Professor Colin Raston. The VFD enables new approaches to producing a wide range of materials such as graphene and sliced carbon nanotubes, with the bonus of not needing to use harsh or toxic chemicals in the manufacturing process (which is required for conventional graphene and shortened carbon nanotube production).
This clean processing breakthrough will also greatly reduce the cost and improve the efficiency of manufacturing these new high quality super-strength carbon materials. The key intellectual property used by 2D Fluidics comprises two patents around the production of carbon nanomaterials, assigned by Flinders University.
2D Fluidics will use the VFD to prepare these materials for commercial sales, which will be used in the plastics industry for applications requiring new composite materials, and by the electronics industry for circuits, supercapacitors and batteries, and for research laboratories around the world.
2D Fluidics will also manufacture the VFD, which is expected to become an in-demand state-of-the-art research and teaching tool for thousands of universities worldwide, and should be a strong revenue source for the new company.
Managing Director, Craig McGuckin said “First Graphene is very pleased to be partnering Professor Raston and his team in 2D Fluidics, which promises to open an exciting growth path in the world of advanced materials production. Access to this remarkably versatile invention will complement FGRs position as the leading graphene company at the forefront of the graphene revolution.”
Professor Colin Raston AO FAA, Professor of Clean Technology, Flinders Institute for NanoScale Science and Technology, Flinders University said “The VFD is a game changer for many applications across the sciences, engineering and medicine, and the commercialisation of the device will have a big impact in the research and teaching arena,” Nano-carbon materials can replace metals in many products, as a new paradigm in manufacturing, and the commercial availability of such materials by 2D Fluidics will make a big impact. It also has exciting possibilities in industry for low cost production where the processing is under continuous flow, which addresses scaling up - often a bottleneck issue in translating processes into industry.”
Advanced materials company, First Graphene Limited (“FGR” ) has announced an update on its work with the Swinburne University of Technology (SUT) on the development of a new energy storage technology using graphene, referring to their new product as the "BEST™ Battery".
While it is generally accepted that lithium-ion batteries are the state-of-the-art energy storage device available for consumer products today, they are not without their issues. In particular, there are examples where they have been the cause of fires in some instances. There is a vast number of companies and research institutions working to provide safer, more reliable and longer life batteries which utilise materials other than lithium-ion. Some of these involve the use of graphene.
First Graphene, through its research and licencing agreements with Swinburne University of Technology, is pursuing a significantly different path to the development of the next generation of energy storage devices. Rather than trying to improve existing chemical battery technology, it is pioneering the field of advanced supercapacitors which have the potential to change the future for energy storage forever, particularly in handheld and consumer products.
Using the advanced qualities of graphene, First Graphene is developing the BEST™ Battery. This energy storage device promises to be chargeable in a fraction of the time and it will be fit for purpose for at least 10 times the life of existing batteries. It will be significantly safer and more environmentally friendly. All these improvements are made possible because the science relies on physics rather than chemical reactions, and on the remarkable properties of graphene materials.
The table below provides an interesting comparison of key operating parameters of the BEST™ Battery alongside existing lithium-ion batteries and existing supercapacitors available in the market. What is particularly noteworthy is the 10x increase in the energy density expected for the BEST™ Battery, when compared with supercapacitors currently on sale in the market place, and the much lower cost per Wh. These features will provide great commercial advantages.
Table 1: Comparison between BEST™ Target development and existing Li Ion AA Batteries and an existing commercial Supercapacitor.
While the exact details of the design and construction of the BEST™ Battery must remain confidential for reasons of commercial security, First Graphene have disclosed the process of manufacturing the battery involves the use of lasers to create nanopores in graphene-based materials which achieve energy densities more than 10x as great as the pre-existing technology. Practical matters being addressed include the scaling up to the size of the battery from simple laboratory demonstrations of the effectiveness of the science, to devices which will be effective substitutes for batteries used in a wide range of hand held consumer products.
The first few months of the BEST™ Battery development project entailed the recruitment of additional, highly qualified research scientists and the acquisition of specialised equipment needed to prepare and manufacture the components of the BEST™ Battery.
Work has commenced on the improvement of many design aspects in order to optimise the configuration of the battery, with the ultimate objective being to develop a product suitable for mass scale production. At the same time, the methodology of making the battery is being subjected to continuous experimentation to improve the effectiveness and efficiency of the materials and processes used in the device. In addition, the pilot production line for building the BEST™ Battery prototype has been set up, which enables the manufacturing of the BEST™ Battery to meet industrial standards.
Swinburne recently reported that a single layer of the BEST™ Battery prototype that made by the pilot production line was able to sustain an LED globe for a period of 15-20 minutes with only a few seconds of initial charge. This is a very significant outcome, auguring well for the ultimate product which is intended to comprise much more than 100 stacked layers of graphene sheets.
The Ragone plot below tracks the continuing improvements in the performance of the BEST™ Battery.
Figure 1: Ragone Plot demonstrating the progress of the BEST™ Battery development toward its goal
Graphene-Based Flexible Smart Watch
The research being undertaken also involves the development of flexible batteries for smart watches which can be incorporated into the watchband itself. These will be light-weight and flexible, they will be able to be recharged in 1-2 minutes, and they will be fit for purpose for many tens of thousands of cycles. Information will be displayed not only on the watch face, but also on the band itself.
While it is intended that the BEST™ Battery development program will eventually provide suitable substitutes for many devices which currently used flat pack and cylindrical batteries, it will also provide batteries for new, innovative purposes. The thin profile of the Battery, and its flexibility, will make it suitable for use in clothing. It could also be integrated into smart watch bands, as an example, rather than having a solid block configuration. It is already showing excellent ability to convert kinetic energy into stored energy due to the speed at which it can charge i.e. simple movement of shaking can recharge the Battery.
Commenting on these progress, FGR’s Managing Director Craig McGuckin said:
“The demonstration of full scale commerciality of the BEST™ Battery will take time, but so far the results have been very encouraging. The science has been proved at laboratory scale and now we are advancing many aspects of materials used and design processes leading to the development and optimisation of production methodology. We are very pleased that Swinburne University of Technology has advised us that the pilot production line is a world first. We are confident that the advantages offered by our technology will bring revolutionary changes to how we use batteries in the future, with added safety, efficiencies and flexibilities. The BEST™ Battery will be a serious game changer”.
Advanced materials company, First Graphene Limited (ASX: FGR) is working with the University of Adelaide (UoA) on graphene for industrial building products.
Graphene in Concrete
Experiments have been conducted on the use of graphene oxide (GO) being added to concrete to improve both compressive and tensile strength. However the hydrophilic and high resistivity nature of GO limits its applications in things such as ‘smart’ cement.
Due to the high aspect ratio of nano-reinforcements such as graphene and carbon nanotubes, they have the ability to arrest crack propagation in concrete (by controlling the nano-sized cracks before they form micro-sized cracks) and hence greatly improve peak toughness, making them more effective than even conventional steel bar or fibre reinforcements.
Premium Concrete Products – Smart Cement
Ultra-High Performance Concrete (UHPC) operates at such a high-performance level that it competes with steel rather than regular concrete grades. Advantages include lower lead times compared to steel. UHPC can cost in excess of $500/tonne, with enhancements such as micro-reinforcements further increasing the price.
Due to the immense importance of compression strength and other factors such as blast, ballistic and earthquake resistance, additive premiums can be significant. UHPC is over an order of magnitude more expensive than regular concrete, but in an environment where material usage and weight are such essential considerations, it can actually be cheaper to use the more expensive grades in the long run, especially factoring in the reduced maintenance costs incurred by UHPC.
The UoA is testing FGR graphene, with the aim of making “smart cement” with conductive graphene flakes which may;
i. address the concerns of cracking and corrosion, and
ii. provide conductivity for better monitoring the health of concrete structures.
The first test results indicate the addition of just 0.03% standard graphene by weight is the optimal quantity of graphene from the test conducted to date, showing a 22 - 23 % increase in compressive and tensile strength, respectively. The addition of more standard graphene does not increase or decrease the strength of the concrete material when compared to the control in this test work.
Promising Results with Favourable Economics
This initial work has yielded very promising results with very small amounts of FGR graphene required to greatly increase the strength of the materials. Determining the optimum mixing methods and concentration to develop a consistent material will be the key to further developing this project.
The focus of the next stage of the work will be trialling other concentrations of graphene in concrete, specifically loading at 0.01% and 0.1% graphene, and optimisation of the mixing procedures. New methods of incorporating graphene into the concrete mixture will also be trialled.
The graphene provided by FGR will have a range of aspect ratios (smaller sheet sizes) and will be tested over the full range of concentrations. It is anticipated this material will better disperse within the concrete mixture and therefore provide further mechanical strength improvements.
The concrete admixtures market is estimated to be worth US$18.10bn by 2020. The drivers identified for the concrete admixtures demand are growing infrastructure requirements in developing economies, improving economics of construction, and shifting preferences of population towards urbanisation.
Advanced materials company, First Graphene Limited (FGR), has provided an update on its development of the graphene based FireStop™ fire retardant material.
Development of the FireStop™ material is being conducted in conjunction with the University of Adelaide as part of the Company’s participation as a Tier 1 participant in the ARC Research Hub for Graphene Enabled Industry Transformation.
The video below shows the dramatic effectiveness of FireStop™when applied to simple wooden structures. Whereas the untreated structure on the left is totally consumed by fire, the structure treated with the FireStop™ retardant doesn’t even catch fire even after five minutes of trying to light it with a blow torch.
Given that fires generally start at specific ignition points, the ability of a graphene-based retardant to stop the ignition is a key feature of the product. The FireStop™ was applied in three coats, was applied by brush and was less than 500 μm thickness.
Note: There is no sound for this video.
The relevant characteristic of graphene that this demonstration highlights is the very high thermal conductivity i.e. the ability to disburse heat away from the source. FGR is highly encouraged by the results of this simple demonstration, which augers well for subsequent, more advanced and scientifically controlled demonstrations that are being undertaken.
The University of Adelaide has now received a UL-941 system for use in its workshop. It is also installing an LOI instrument for the generation of scientific data. These instruments will enable an acceleration of the test work being conducted to optimise the FireStop™ product and application methodology.
[ UL 94, the Standard for Safety of Flammability of Plastic Materials for Parts in Devices and Appliances testing, is a plastics flammability standard released by Underwriters Laboratories of the United States. The standard determines the material’s tendency to either extinguish or spread the flame once the specimen has been ignited. UL-94 is now harmonized with IEC 60707, 60695-11-10 and 60695-11-20 and ISO 9772 and 9773. ]
Further tests will be conducted to increase the viscosity of the product while maintaining the fire-retardant performance. This work will be the precursor to submitting FireStop™ to FGR’s own testing to the relevant fire standards and to CSIRO for independent testing in Q1 2018. In the meantime, the Company is entering negotiations with potential industry partners for the commercialisation of FireStop™.
Advanced materials company, First Graphene Limited (ASX: FGR ), officially opened its Commercial Graphene Facility (CGF) at a ceremony with Mr Josh Wilson MP, Federal Member for Fremantle, Australia on Thursday 23, November 2017.
FGR Chairman, Warwick Grigor stated “This Facility represents both the completion of one journey and the commencement of another.” The first part of the journey had commenced in May 2015 when testing of FGR’s material was undertaken at the University of Adelaide. “The tests were done, and they confirmed that not only could graphene be recovered, but of the 50 or more types of graphite that Professor Dusan Losic and his team had tested, the vein graphite (from FGR) gave the best results. ”
First Graphene Board Members L to R; Chris Banasik, Peter Youd, Warwick Grigor and Craig McGuckin
Mr Grigor added, “ There are two very impressive aspects of this wonderfully innovative venture. The first is the very short time frame in which it has been achieved. The second is the very small expenditure that has been involved. Both are a credit to the resourcefulness of the FGR team, led by ourManaging Director, Craig Mc Guckin.Through careful management and sourcing ofequipment for this production facility, management has been able to achieve excellent costs reductions. In many cases these savings have been up to 80%. Rather than accept off-the-shelf quotes from German suppliers, Craig has engaged with manufacturers in China to design and procure equipment at significant savings. That is what good management does for a company.”
MrJoshWilson MP,Federal Member for Fremantle speakingat theofficial opening.
Officiallyopening the facility Mr Wilson remarked“It really is no exaggeration to say that graphene will likely be one of the defining substances and technologies of the 21st century.It is wonderful that the enormous potential of graphene will be explored and enabled through a production facility here in Henderson; in the Fremantle electorate; in the state of Western Australia.It’s exactly the kind of smart, innovative, cutting- edge business that we should be in; that we need to be in.”
Mr Wilson went on to state “I expect that the development of processes and applications that involve graphene– like the development of renewable energy technology; like innovations in medical science– will have a particularly profoundbeneficialimpactincountriesthatfacedevelopment challenges, including a number of countries in our region.Making a contribution to lifting the standard of living and the quality of life the world over through invention and innovation is a great Australian tradition."
