摘　　要：One popular study of the recent research is to develop the cathode materials for lithium-ion batteries. As a new cathode material for lithium-ion batteries, the LiNil/3Col/3Mnl/3O2 has drawn widespread attention because of its high capacity, high cut-off voltage and high tap density. Its theoretical capacity is 277.8 mAh/g. The crystal structure of LiNil/3Col/3Mnl/3O2 is α-NaFeO 2 . The structural and morphological features of the LiNil/3Col/3Mnl/3O2 are introduced in this paper. The emphasis is to present the methods for promoting electrochemical properties. The electrochemical properties and structure characteristics are discussed. And the prospect of layered LiNil/3Col/3Mnl/3O2 is forecast in the end.One popular study of the recent research is to develop the catnocte materials tor lltnlum-lon oatterles.
