Yesterday's battery performance update was big for Graphene Manufacturing Group (GMG.v GMGMF). 


The update showed that GMG's Graphene A-I  Batteries have 93% more energy density and 33% more power density than they had in the last update in June 2021.


 


Their test batteries also showed a much higher success and pass rate which is a big step toward commercial production.
