| Abstract: | Based on the relation between its structure and properties,synthesis and modification of LiNiO 2 cathode material for lithium-ion batteries were discussed.Doping it with other ions was regarded as the most effective way for improving its properties.The increase of covalency and polarity energy in the O-Ni-O sheets by doping was beneficial to the stability of 2D layered structure and the electrochemical properties for LiNiO 2 cathode material. |
