摘　　要：从结构与性能的关系出发对锂离子电池正极材料LiNiO2 的制备与掺杂改性研究进行了讨论。认为在优化合成条件的基础上进行掺杂改性是提高其性能的最有效手段 ,通过掺杂能导致O -Ni -O夹层共价性提高和极化能增大的阳离子 ,有利于LiNiO2Based 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.
