GMG reports doubling energy density of 6 minute charging graphene aluminium-ion battery

Graphene Manufacturing Group (GMG) has provided a progress update on its Graphene Aluminium-Ion Battery technology (“G+A CELLS”) being developed by GMG and the University of Queensland (“UQ”) under a Joint Development Agreement with Rio Tinto, one of the world’s largest metals and mining groups, and with the support of the Battery Innovation Center of Indiana (“BIC”) in the United States of America.

Increase in Energy Density for G+A CELLS since December ’25 Update

The GMG G+A CELLS have reportedly demonstrated superior performance characteristics when compared to a representative market leading ultra-fast charging batteries, the Lithium Titanate Oxide (“LTO”) batteries, which can be sold at a premium price of up to US$1200/kWh.
