GMG provides graphene aluminium-ion battery performance data.
Graphene Manufacturing Group Ltd. announce the initial performance data when tested in coin cells for the patent-pending surface perforation of graphene in aluminium-ion batteries developed by the Company and the University of Queensland (“UQ”).
The experiments were performed at the Australian Institute for Bioengineering and Nanotechnology (“AIBN”) at UQ. Initial performance data is presented below. Currently, GMG Graphene is being used to produce coin cell prototypes for customer testing in Q4 2021.
GMG announced recently the execution of a research agreement with UQ’s AIBN to develop graphene aluminium-ion batteries (please refer to the Company’s News Release dated April 22, 2021, for further details).

Under the agreement, GMG will manufacture commercial battery prototypes for watches, phones, laptops, electric vehicles and grid storage with technology developed at UQ. GMG has also signed a license agreement with Uniquest, the University of Queensland commercialisation company, which provides GMG an exclusive license of the technology for battery cathodes.
Craig Nicol, GMG CEO and Managing Director said:
We are currently looking to bring coin cell commercial prototypes for customer testing in 6 months and a pouch pack commercial prototype – used in mobile phones, laptops etc. – for customer testing in 18 months.
“We are really excited about bringing this to market. We aim to have a viable graphene and coin cell battery production facility project after customer validation that we would likely build here in Australia,” said Craig Nicol.
Dr Ashok Nanjundan, GMG’s Chief Scientific Officer, said.
This is a real game-changing technology which can offer a real alternative with an interchangeable battery technology for the existing lithium-ion batteries in almost every application with GMG’s Graphene and UQ’s patent-pending aluminium ion battery technology.
“The current nominal voltage of our batteries is 1.7 volts, and work is being carried out to increase the voltage to directly replace existing batteries and which lead to higher energy densities.”
“The real differentiator about these batteries is their very high power density of up to 7000 watts/kg, which endows them with a very high charge rate. Furthermore, graphene aluminium-ion batteries provide major benefits in terms of longer battery life (over 2000 charge / discharge cycles testing so far with no deterioration in performance), battery safety (very low fire potential) and lower environmental impact (more recyclable),” said Dr Ashok Nanjundan.
GMG will make further disclosures regarding the performance and development of these graphene aluminium ion batteries as the research and development program progresses.
