Impact of surface coating on electrochemical and thermal behaviors of a Li-rich LiNiMnCoO cathode.

Lithium-rich layered oxide materials are considered as potential cathode materials for future high-performance lithium-ion batteries (LIBs) owing to their high operating voltage and relatively high specific capacity. However, perceptible issues such as poor rate performance, poor capacity retention, and voltage degradation during cycling need to be improved before the successful commercialization of the material. In this report, zirconia coated LiNiMnCo8O (NMC) (where ZrO = 1.
