Graphene Manufacturing Group ships lithium-free G CELLS to customers

Australia's Graphene Manufacturing Group has delivered its first lithium-free G CELLS to customers for testing. The 1.5 Ah pouch cells ran 1,000 six-minute cycles with no capacity loss — roughly ten times the cycle life of LTO reference cells, which lost 20% within 82 cycles.

• 1,000 six-minute cycles with zero capacity loss for G CELLS
• LTO reference lost 20% capacity within 82 cycles
• Energy density 58 Wh/kg, 94% round-trip efficiency vs 64% for LTO
• Cells ran 4 °C above ambient vs 19 °C for LTO
