Graphene Manufacturing Group said on April 15 that its graphene aluminium-ion battery cells doubled energy density to 49 Wh/kg, while maintaining six-minute charging performance over hundreds of cycles. The company says customer testing is planned for 2026 and small commercial production for 2027, but the program remains at battery technology readiness level 4.
Graphene Manufacturing Group said its six-minute-charging graphene aluminium-ion battery cells doubled energy density to 49 Wh/kg, a development that brings the program closer to customer testing later in 2026 and small commercial production in 2027.
Graphene Manufacturing Group said April 15, 2026, that its six-minute-charging graphene aluminum-ion battery cells reached 49 Wh/kg, doubling the company’s December 2025 figure and sharpening the path toward customer testing in 2026 and small commercial production in 2027.
Graphene Manufacturing Group has approved the final AU$1.4 million needed to complete its Gen 2.0 graphene plant in Brisbane, a move that keeps the 10-ton-per-year facility on track for mid-2026 commissioning.
Graphene Manufacturing Group says its aluminum-ion battery now reaches 49 Wh/kg in testing, up from 26 Wh/kg in December, a gain the company says moves the cell closer to commercial validation.
Graphene Manufacturing Group has appointed Stuart Watson, a former global technical development head at Rio Tinto, as chief production growth officer while saying its second-generation graphene plant in Queensland remains on track for commissioning by the end of June 2026.
