Last month, Australia-based Graphene Manufacturing Group (GMG) announced a research agreement with the University of Queensland’s Australian Institute for Bioengineering and Nanotechnology (AIBN) for the development of graphene aluminum-ion batteries. Now, GMG has shared 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). Currently, GMG Graphene is producing coin cell prototypes for customer testing in Q4 2021.
Under the recently announced 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 commercialization company, which provides GMG an exclusive license of the technology for battery cathodes.
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. Nanjundan.
Great news on this. Lithium-ion batteries had barely half the energy density of these when they first came out. Even if they only reach current lithium-ion levels, they would still be a big leg up. Looking forward to its commercialisation!

The big question now is cost. The Lithium battery industry is now pretty mature but if the Al/Craphene can rel place it it will be a big jump as regards safety and re-cycling. The operational costs of ELECTRIC vehicles is mostly down to the TAX regimes applied to fossil fuels and sooner or later every government will be forced, for purly financial reasons, to look at ways to replace the income derived from FOSSIL FUEL TAXES So any move towardscheaapr vehicles and batteries will becom every important Until Electric cars comedown to a reasonable consumer price they will only be a specialised market. There will have to be at some point elctric vehicles inn thwe $£GB 7- 15.000 range with at least a 250 mile range and if the Al/Graphenebattery with a higher charge density helps that then it will bea break through
The UK has stated that ALL NEW fossil fuelled cars will be banned from 2030. That's all very well but outside of say the G7 Nations will be able to afford them. Indeed with a price in the high £GB30,K for a decent sized model with decent and expected 'add-ons' only minority will be able to afford them in the G7. And where do you put a chain of charging stations in the bloody Sahara or the Antarctic , the jungles of just about anywher even the Australian Outback.
