Lithium Oxide Cobalt Powder (LiCoO2) Benchmark Battery Materials

Product Description

Lithium cobalt oxide (LiCoO2 or LCO), CAS number *********3, is a benchmark battery material that replaces lithium metal as cathode for greater stability and capacity. This high performance LCO cathode material dominates in computer, communication, and consumer electronics-based lithium-ion batteries (LIBs) with the merits of easy procession, unprecedented volumetric and gravimetric energy density, and high operation potential.

LiCoO2 possesses a high theoretical specific capacity (**4 mAh/g) and high discharge voltage (~4.2 V vs Li+/Li). However, when half of the Li+ are removed roughly at 4.0 − 4.2 V, it causes an abrupt change in configurational entropy (ΔS) and leads to structural instability. Consequently, commercial LiCoO2 exhibits a maximum capacity of only ~**5 mAh/g.
