GMG trumping lithium batteries in energy density and more Graphene Manufacturing Group's (GMG.v GMGMF) Graphene Aluminum-Ion coin-cell battery prototypes are outperforming Lithium Ion batteries in several ways including charging speed and fire safety.
GMG has also greatly increased the energy density of their coin-cell batteries to 290 - 310 Wh/kg, trumping lithium coin-cells.
In this interview that focuses on these prototypes, Nicol shares that GMG is also working towards harnessing 2 additional Alumium electrons to even further increase the batteries' energy density https://www.youtube.com/watch?v=_cm3NlQUZlA
