A company named Graphene Manufacturing Group is developing an Aluminum-Graphene battery with very high power output, and good battery life:
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.
