AbstractThis proposal targets developing a safe, high-rate, ultra-high capacity 18650-size cell with a minimum capacity of 4 Ah, a minimum specific energy of 300 Wh/kg, able to provide at least 100 cycles at C/3 charging and discharging rates. The cell achieves this performance by the use of a novel, highly reversible, pre-lithiated, Si nano-composite negative with a novel ceramic layer on the electrode surface besides the high capacity positive (>300 mAh/g). This cell is intended for military batteries such as Land Warrior battery (4S4P) and BB2590 battery (8S3P), but will have other applications as well.
