| 摘 要： | 综述了锂离子电池正极材料热稳定性的研究现状及其进展。针对正极材料LiCoO_2,LiNiO_2,LiMn_2O_4及其衍生物的热稳定性,众多研究者提出了不同的反应机理,认为正极材料的热稳定性与颗粒大小、晶体结构、充/放电状态、脱锂程度及电解质性质等因素有关。可以利用掺杂技术、涂层技术及优化合成条件等手段来改善正极材料的热稳定性。

| Abstract: | The current researches and developments of thermal stability of positive materials for lithium-ion batteries are reviewed in the paper. Emphasizing on thermal stability of LiCoO_2, LiNiO_2, LiMn_2O_4 and their derivatives, researchers have introduced many different mechanisms. They think the thermal stability is related to some factors such as particle size, crystal structure, charge/discharge, the extent of delithiated,electrolytes. In order to improve the thermal stability of positive materials,doping ,coating and optimizing synthetic methods may be used. |
