摘　　要：The flourishing development of lithium-ion batteries(LIBs)has accelerated the manufacturing of potable electric devices,electric vehicles(EVs)and hybrid electric vehicles(HEVs).Lithium-rich layered oxide(LLMO)cathode materials are receiving international attention because they can deliver an exceptionally high rechargeable capacity of 250 mAh/g between 2.0 V-4.8 V.However,this high capacity cathode material still faces challenges,such as transition metal(TM)dissolution occurs at high electrode potentials(>4.5V vs.Li/Li+),and the evolution from layered structure to spinel-like upon cyling leads to the poor cycle life.Therefore,we have tried to synthesis LLMO cathode materials by sol-gel method and modify them via surface coating approach in this paper.
