Replacing flammable and volatile organic liquid electrolyte with the solid-state electrolyte is one of the efficient ways to improve the safety of lithium batteries. However, there are still several issues in solid electrolytes, including low ionic conductivity, unstable interface, poor chemical/electrochemical stability etc., which hinders their real application.
In recent, Professor Yanwei Ma, from the Institute of Electrical Engineering, of the Chinese Academy of Sciences summarized the strategies to boost ionic conductivity and interface compatibility of inorganic - organic solid composite electrolytes. The review was published in Energy Storage Materials.
This review introduces the main strategy to improve the ionic conductivity of the active–inorganic-fillers based solid composite electrolytes (SCEs) and interface compatibility of electrodes/solid electrolytes, and presents the perspective on the future research. It is an important guidance to the design and preparation of high-performance solid electrolyte and the application in all-solid-state lithium batteries.
