Graphene Manufacturing Group Ltd. (TSXV: GMG) ("GMG" or the "Company") is pleased to provide the latest progress and performance update on its Graphene Aluminium-Ion Battery technology ("G+AI Battery") being developed by GMG and the University of Queensland ("UQ") and the GMG battery grade graphene production quality program.

Notably, this update includes information about GMG's G+AI Battery regarding:

  • GMG's Graphene Aluminium-Ion Battery calculated energy density has increased to 290-310 Wh/kg, an increase of 93% since the last battery update on 22nd June 2021
  • Power density has also increased to around 9,350 W/kg, a 33% increase since previous update
  • Battery cell enhancements and repeatability
  • Growing confidence in repeatability of battery grade quality graphene production at scale
  • Next steps toward commercialisation

Improved Battery Technology Performance

Ongoing development from GMG's Battery Team has resulted in a significant increase in battery performance of GMG's Graphene Aluminium-Ion Battery. Latest testing data has demonstrated a calculated energy density that has increased by 93% from 150-160 Wh/kg to 290-310 Wh/Kg since the last battery update on the 22nd of June 2021 ("PreviousAnnouncement").

Performance data presented in this release was calculated off GMG's specific coin cell design and testing data, which has been separately verified by the Australian Institute for Bioengineering and Nanotechnology at the UQ as against other aluminium ion batteries and two commonly used lithium-ion batteries produced and used worldwide (see table and graph below).

GMG's CEO Craig Nicol stated, "These results show the promise of GMG's Graphene Aluminium-Ion Battery in terms of performance on top of previously announced longevity and sustainability advantages. The outcome was the result of a large piece of work done by GMG's Battery Team to repeatably make successful batteries, improve almost all of the various components of the battery and the successful transfer of intellectual property from the UQ team."

Guy Outen, GMG's Chair added, "I'm delighted with this battery performance update which reflects both the tremendous creativity and hard work of all involved as well as the possibilities of our G+Al Batteries, even at this early stage in their development. This is a significant step in the development of our G+AI batteries and we look forward to the next steps towards commercialisation."

This performance improvement is a result of increasing the two main parameters since the Previous Announcement of:

  • ~ 61% increase in the battery's specific discharge capacity from 200 to 360mAh/gram and
  • ~ 17% increase in the nominal voltage from 1.7 V to 2.0 V.

The following chart shows this latest performance achieved:

Source: GMG testing. All testing was carried out on coin cells with GMG Graphene in Aluminium Ion Battery at ambient temperature cycling from 2.7V to 0.5V, 4.5 Coulomb (2.2A/g) charge rate

This improvement in performance was associated with GMG successfully transferring the intellectual property from UQ's laboratories to GMG's Battery Development Centre and Battery Team. GMG now achieves a higher success and pass rate for the cells it makes for development and testing purposes which is a step towards commercial production.

GMG's Battery Team has conducted work across the entire cell design (as per Figure 1) to improve performance, longevity, and ease of manufacture assembly including:

  • Optimisation of the cathode substrate material selection and its preparation
  • Repeatable graphene ink cathode preparation process
  • Optimisation of selected cathode mixing fluid
  • Optimisation of selected cathode binder
  • Optimisation of the cathode thickness (given various loading options of low, medium and high)
  • Reduction of internal resistance of the battery
  • Stable and repeatable preparation and testing of the electrolyte to optimise cell performance
  • Initial multilayer cathode design and production
  • Initial multilayer cathode pouch cell design
  • Present optimisation of the charging current for starting of the battery
  • Present optimisation of the charging voltage for starting of the battery
  • Successful removal of corrosion of the internals from the electrolyte

Repeatable Battery Grade Graphene Quality

GMG's CEO Craig Nicol stated, "The Company's confidence is growing in the GMG developed scalable process to make graphene from natural gas to a definable and tuneable graphene type for the GMG G+AI Battery in a repeatable fashion. Further testing is planned in the near term to further validate this confidence."

GMG has also assessed battery performance with several different grades of GMG produced graphene using industry standard tests and have demonstrated repeatable and reproducible performance. GMG has increasing confidence that it has found an economically sustainable path to scale the graphene process. On this basis the Company will continue to work towards a final investment decision for first battery production.

GMG also compared the performance of the GMG made graphene, to graphene made by other processes by several other companies and identified GMG's graphene as having more favourable specific discharge capacity, ie. a higher energy density performance. The Company expects ongoing iteration and improvement over time of both the graphene quality from the GMG graphene production process, as well as the G+AI Battery performance as GMG further develops, deploys and scales both of these technologies.

G+AI Coin Cell Development

The next steps for the coin cells (as seen in Figure 2) are to undertake further engineering and development activities to achieve a coin cell capacity for the desired product application(s) being targeted for initial customer sales.

If this is achieved, subject to government approvals the Company's Board will consider a Final Investment Decision ("FID") for an automated coin cell factory and any (further) graphene production capacity expansion required. As part of the FID, GMG's Board considerations will include, but not be limited to, binding customer sales contracts, the economic costs to build an automated coin cell factory and other operational-level production considerations. GMG is targeting a FID decision in 2023 and the latest production to commence in 2024.

As a precursor, GMG has already committed to invest AU$1.5 million into expanding and relocating its graphene production operations into an adjacent warehouse to its existing headquarters and Battery Development Centre (totalling 3,500 square meters) in Richlands, Queensland, Australia, as announced by GMG on 17 August 2022.

G+AI Pouch Cell Development

The next development steps for the pouch cell (as seen in Figure 3) will follow a similar sequence to the initial development of the coin cell.

When completed GMG will look to update the Technology and Product Road Map for the pouch cell and finalise the end application(s) for the initial market/customer for the pouch cells and therefore finalise the targeted pouch cell capacity. The Company continues to work under confidentiality agreements with a range of potential customers as input to this decision.

Upon finalising the target market, size and location of the plant and after various conditions are met, the Company may take FID on an integrated gas to graphene and automated pouch cell factory at likely a new location to account for its potential scale. The Company hopes to make significant progress on the pouch cell in 2023.
