GMG shares further updates on aluminum-ion coin cell batteries performance

Australia-based Graphene Manufacturing Group (GMG) recently shared initial performance data from tests performed on coin cells for the patent-pending surface perforation of graphene in aluminium-ion batteries developed by the Company and the University of Queensland (“UQ”). Now, GMG revealed further performance data of these graphene aluminium-ion coin cell batteries.

The experiments were performed at the Australian Institute for Bioengineering and Nanotechnology (“AIBN”) at UQ. Testing reportedly confirmed a very high cycle rate for graphene aluminium-ion coin cell batteries together with minimal reduction in performance over a 3,000 cycle experiment period (which includes charging up to full charge and discharge down to near full discharge) at very high charging rates – including at 2 Ampere per gram (“A/g”) of cathode material for 1000 cycles, 5 A/g of cathode material for 1000 cycles and then 10 A/g of cathode material for a further 1000 cycles.
