High Voltage, High Capacity Lithium Cobalt Oxide, LiCoO2 (LCO) Powder, 500g, 14.0~ 18.0 um D50, Cathode Material

John B. Goodenough's research group first discovered lithium cobalt oxide as an intercalation electrode in 1980. Lithium cobalt oxide is now widely used as the cathode material of choice in rechargeable lithium-ion batteries found in consumer electronics products. Although the theoretical capacity of traditional LiCoO2 is 273.8 mAh/g, its capacity is limited by the voltage range (3.0~4.2 V) due to the irreversible phase transition LiCoO2 of above 4.2 V. This novel LiCoO2 can be cycled up to 4.5 V (4.4 V recommended) with high capacity. It can typically deliver a capacity of 190.6 mAh/g at 0.1 C and 180.2 mAh/g at 1 C when cycled between 3.0 and 4.5 V.
