[{"type":"text","content":"GMG Unveils Graphene Aluminium-Ion Battery That Fully Charges in 6 MinutesBrisbane, Australia--(Newsfile Corp. - December 15, 2025) - Graphene Manufacturing Group Ltd. (TSXV: GMG) (OTCQX: GMGMF) (\"GMG\" or the \"Company\") is pleased to provide the latest progress update on the Graphene Aluminium-Ion Battery technology (\"G+AI\") 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.Based on its current state of development as reflected below, the GMG G+AI Battery has similar performance characteristics to those provided by High Power Lithium Titanate Oxide (\"LTO\") batteries, which are sold at a premium price of up to US$1500/kWh. However, the GMG G+AI Battery can be produced at a substantially lower cost and therefore can be priced below that of LTO batteries. In 2025, sales of LTO batteries, which are used in many applications globally, totalled US$ 5.6[1] billion.Battery Performance Update:GMG is pleased to announce that it has progressed its G+AI Battery technology and believes that, once development is completed, it can meet the key target specification requirements for the main targeted battery use case as per Figure 1, including:Charging in under 6 minutes;Energy density > 100 Wh/kg after 1 hour of charging;Long Cycle Life (10,000 cycles);Safe (no Lithium);Lower Thermal Runaway Risk; andLikely no thermal management system will be needed.Bob Galyen, GMG Non-Executive Director, commented: \"In my nearly five decades in the battery industry, I have rarely seen a technology with the disruptive potential of GMG's next-generation graphene aluminium-ion battery. With the possibility of charging from empty to full in around six minutes, this chemistry fundamentally changes how designers can think about electric vehicles, consumer electronics, and stationary storage. Instead of planning around long charge stops with large packs, engineers can optimise for rapid energy turnaround, with higher power, and safer, with GMG's battery made from abundant raw materials. Lithium-ion will remain a key part of the energy landscape for years to come, but its limitations in fast charging, temperature tolerance, and crit...
