摘要：
Lithium ion battery has high energy density and good cycle performance. It is the most ideal power supply and energy storage system at present. However, due to the immature technology of high-capacity and high-power lithium-ion battery and potential safety hazards, its commercial application has been limited to a great extent. The safety problems of lithium-ion battery mainly include mechanical damage, abnormal charging, gas accumulation and thermal runaway. This paper analyzed the causes of the above risk factors and the suppression methods. Among these methods to enhance battery safety, the use of safety additives was the most economical and effective means, but it was not easy to find a practical additive with high safety performance for the battery without sacrificing other performance in the electrolyte. In the future, multifunctional additives would be the most promising research direction for improving battery performance. This paper briefly analyzed the action mechanism of film-forming additives, flame retardant additives and anti overcharge additives, and prospectd the development direction of related fields. © 2022 Chemical Industry Press.
