Research on the Current Status and Improvement Methods of Electrolytes for Lithium ion Batteries

Owing to their high energy density among other beneficial features, lithium-ion batteries (LIBs) enjoy extensive application across sectors including aerospace engineering, civil transportation, and electronic device manufacturing. Nonetheless, the LIBs electrolyte presents certain drawbacks, which contribute to the diminishing performance of these batteries and pose risks to environmental safety. Considering these issues, the paper begins by presenting the operational principles of LIBs and examining the constituents of the electrolyte and discusses the roles of the individual components. Then, the causes of the problems and proposes improvement strategies are summarized. The working stability of LIBs at extreme temperatures can be improved by a series of measures, such as adding flame retardants and optimizing the composition of electrolytes. The aim of the research is to resolve the current problems with LIBs electrolytes and enhance the applicability and stability of LIBs in various practical situations.
