摘要
从有机电解液自身热稳定性以及电极／有机电解液相互作用的热稳定性两个方面综述了锂离子电池有机电解液的热稳定性;认为,正极／有机电解液的反应对锂离子电池安全性的影响是最主要因素。并分别从抑制LiPF6分解、使用不燃或阻燃溶剂阐述了改善有机电解液热稳定性的方法。
The thermal stability of organic electrolyte solution itself, and the thermal stability of the reactions between electrode and organic electrolyte solution were all reviewed. It's believed that, the effects of reactions between positive electrods and organic electrolytes on security of Li-ion battery are one of the important elements. The methods to improve the thermal stability of organic electrolyte solutions were also reviewed from the below: (1) reducing the decomposition of LiPF6, (2) applying nonflammable or flamma-bility-retarded solvent as cosolvents or additives.
