Abstract
En 中文
This review introduces solid electrolytes based on sulfide/polymer composites which are used in all-solid-state lithium batteries, describing the use of polymers as plasticizer, the lithium-ion conductive channel, the preparation methods of solid-state electrolytes (SSEs), including dry methods and wet methods with their advantages and disadvantages. In addition, the physicochemical stability of sulfide/polymer composite based solid-state electrolytes is analyzed. The sulfide/polymer composite based solid-state electrolyte can be utilized in lithium metal or lithium sulfur batteries. However, there are still many problems left to be solved in practical applications of these solid-state electrolytes. In this review, several solutions are explored. Firstly, the ultra-long life cycle of batteries can be achieved by thinning the composite electrolyte. Secondly, when sulfur is applied as the positive electrode, the thinning electrolyte can reduce polarization and other problems. Finally, an integrated battery is employed to reduce the interface impedance. By addressing these aspects, the review aims to provide valuable insights into the future development of high-performance solid-state electrolytes in lithium battery technology.
