Layered LiMO2(M=Co,Ni and Mn) materials were widely applied in Li-ion batteries for the mobile electronic devices from the past and present.As the development of the 3G products and power source for EV and HEV,the positive material was required with some special characters.The progress in surface modification(coating) and doping-substituting of the layered LiMO2 and the effects of cation mixing between Li+ and Ni2+ in Li layer on the cycle performance,rate capability and thermal stability of battery were in...
