Superior High Energy Density and High Rate Rechargeable Lithium ion Battery for Army applications

LithChem Energy (LCE) will develop a new ultrasafe rechargeable lithium-ion cell/battery which has higher recharge rate (>C/3 rate), higher energy density (>165 Wh/kg), higher discharge rate (>6C rate) and with the maximum operating voltage of 4.8 V. This new cell will be the building block for the new all-American cell and battery for the BB2590 Warfighter battery increasing performance and decreasing weight. This lithium-ion cell/battery will be based on at least one novel cathode material which has not been used for lithium-ion batteries coupled with nano range carbon for the anode. The gain in energy density results from this novel high capacity cathode material (150 Ah/g) and the increase in cell operating voltage from 3.7 V for standard lithium cobaltate lithium-ion cells to 4.8 V for this new cell. The gain in recharge rate (>C/3) and in discharge rate (>6 C) results from the use of nano cathode and anode materials. LCE has already developed the novel protective coating for the new cathode materials and will develop the higher voltage electrolyte (4.8 V) for stable recharge/ discharge cycling. It will also exceed all of the proposed requirements for the plug-in hybrid electric vehicle (PHEV) and the all electric vehicle (EV).
