GMG Doubles Energy Density of Fast-Charging Graphene Aluminium-Ion Batteries

Key Facts

1GMG announced it has doubled the energy density of its 6-minute charging Graphene Aluminium-Ion (G+AI) battery cells.
2The technology is being developed with the University of Queensland, Rio Tinto, and support from the Battery Innovation Center (BIC) in the USA.

Graphene Manufacturing Group (GMG) has announced a significant technical breakthrough by doubling the energy density of its Graphene Aluminium-Ion (G+AI) battery cells, which boast a rapid 6-minute charging capability. The technology is being developed in strategic collaboration with the University of Queensland and Rio Tinto, with additional support from the Battery Innovation Center (BIC) in Indiana. This advancement aims to enhance the commercial viability of non-lithium battery alternatives, offering faster charging and improved safety profiles compared to traditional solutions. By improving energy density, GMG is positioning its technology to potentially reduce global reliance on Chinese-dominated lithium supply chains. The involvement of major industry players like Rio Tinto adds significant credibility to the project's scalability. This milestone represents a crucial step forward for the EV and energy storage sectors seeking high-performance, sustainable battery technologies.
