Rechargeable Li-based batteries are recommended as a promising power source to fulfill stringent requirements for wearable/portable electronics, electric vehicles (EV), and grid-scale energy storage system (ESS). However, the use of flammable organic liquid electrolytes continues to pose a serious threat to cell safety. To date, (sulfide or oxide-based) inorganic solid electrolytes have been extensively investigated as attractive candidates; however, their longstanding problems, which include poor ionic conductivity, high grain boundary resistance, mechanical brittleness, chemical/electrochemical instability and complicated synthetic processes, pose a formidable challenge to their practical application. In this presentation, focused on development status of solid-state organic/inorganic composite electrolytes for addressing the above-mentioned problems with solid electrolytes, which lie far beyond those achievable with conventional battery technologies. |
