Abstract：The application scenarios of high-power lithium-ion battery terminals are becoming increasingly diversified,and the requirements for battery power performance also need to be enhanced.This paper studied a combination of sulfur-containing electrolyte applied in high-power lithium-ion batteries,and compared with a single-component sulfur-containing electrolyte,and tested the mixed pulse power characteristics,rate discharge,high-temperature charge retention ability and capacity recovery rate,and rate cycle performance.The results show that the 1%ethylene sulfonate(DTD)+0.3%methylene methanesulfonate(MMDS)sulfur-containing electrolyte has higher film-forming quality,better rate discharge performance,better high-temperature storage performance and better rate cycle performance than the 0.5%1,3-propanesulfonic acid lactone(PS)single component sulfur-containing electrolyte.
