Abstract

Ni-rich layered material can be regarded as an one of the promising cathode for high-energy lithium ion batteries. In this paper, Ca-doped Ni-rich LiNi0.8Co0.1Mn0.1O2 cathode material is prepared to investigate the effect of Ca doping on the structural properties and electrochemical performances. In structural properties, there is no obvious difference between the two samples in terms of crystallinity or morphology. In electrochemical performances, the initial capacity and electrochemical behavior are almost identical, while the degree of capacity deterioration in long-term cycle performance is obviously different. This is because Ca doping can increase the bond dissociation energy and pathways for electrons and lithium ions
