Brisbane-based Graphene Manufacturing Group Ltd. (GMG) announced on April 15, 2026, that it has doubled the energy density of its Graphene Aluminium-Ion Battery (G+A CELLS) technology. This breakthrough, developed with the University of Queensland, Rio Tinto, and the Battery Innovation Center of Indiana, allows for a charge time of just six minutes, a feature that could challenge the dominance of existing lithium-ion batteries in the electric vehicle and energy storage sectors.
"This is a significant step forward in the development of our G+A CELLS," a GMG spokesperson said. "Doubling the energy density while maintaining a rapid charging time addresses two of the biggest challenges in battery technology."
The improved G+A CELLS technology now offers a compelling alternative to the lithium-ion batteries that power the majority of today's electric vehicles and consumer electronics. While specific energy density figures were not disclosed, the combination of high energy density and ultra-fast charging could significantly reduce range anxiety for EV owners and enable new possibilities for energy storage solutions. The company did not disclose the test conditions for the comparison.
This development positions GMG as a potential leader in next-generation battery technology, with major implications for the industry. The advancement could disrupt the market share of established battery manufacturers such as Panasonic and LG Chem, and impact automotive giants like Tesla and BYD who are heavily invested in the lithium-ion supply chain. GMG's stock (TSXV: GMG) is expected to react positively to the news, as investors weigh the potential of this new technology to capture a significant portion of the growing battery market.
