With the growing shortage of global energy and resources, the development of new energy material has become the focus of worldwide attention. Lithium ion batteries have drawn great attention due to its high voltage, high energy density, long cycle life, low self-discharge and so on. In this paper, the development of cathode material of lithium ion batteries was reviewed in detail. The synthesis of LiNio.8Coo.1Mn0.1O2through co-precipitation and the coated of LiNi0.8Co0.1Mno.102were deeply investigated, and ...
