UQ, GMG graphene-enhanced aluminum-ion batteries show very high power density, long life - Green Car Congress
Australia-based Graphene Manufacturing Group Ltd. (GMG) reported initial performance data for graphene-enhanced aluminum-ion batteries developed by GHG and the University of Queensland (UQ). The experiments were performed at the Australian Institute for Bioengineering and Nanotechnology (AIBN) at UQ. GMG graphene is being used to produce coin cell prototypes for customer testing in Q4 2021.

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 aluminum 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 aluminum-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).—Dr Ashok Nanjundan, GMG’s Chief Scientific Officer
