Graphene A-I coin cells continue to improve🔋🔋 Graphene Manufacturing Group (GMG.v GMGMF) is getting very close to finalizing the design of its coin cell Graphene Aluminium-Ion batteries as it continues to make strides with its prototypes
GMG's most recent coin-cell battery prototype showed 93% increased energy density, and 33% increased power density compared to their previous prototypes.
+ GMG's batteries continue to produce less external heat than lithium-ion batteries, making them much more fire-safe.
