| 摘 要： | 锂离子电池正极材料LiNiO2存在合成困难、循环性能差和热稳定性差等问题．这些问题都与LiNiO2本身的晶体结构有关．本文从LiNiO2晶体结构入手，分析了产生这些问题的原因，并对解决这些问题的办法进行了简要的综述．现有研究资料表明，仅仅通过优化合成条件只能在一定程度上改善LiNiO2的循环性能，要从根本解决LiNiO2的存在问题，关键是通过掺杂改性稳定其晶体结构． |
| 关 键 词： | 锂离子电池 正极材料 LiNiO2 存在问题 解决办法 |

| Abstract: | As a cathode material for lithium ion batteries, LiNiO2 has various drawbacks such as difficulty to be synthesized, poor cycling performance and poor thermal stability, which are all related to its crystal structure. Stared from the crystal structure, this paper analyzed the causes that result in these drawbacks and reviewed the improve ways briefly. It was shown that just optimizing the synthesis conditions could only improve the cycling performance to a degree. In order to overcome these drawbacks thoroughly, the most important thing is to stabilize the layered structure of LiNiO2 by part substitution of suitable elements for nickel or/and oxygen. |
| Keywords: | lithium ion batteries cathode LiNiO2 drawbacks improve ways |
