ALL SOLID-STATE ELECTROLYTE COMPOSITE BASED ON FUNCTIONALIZED METAL-ORGANIC FRAMEWORK MATERIALS FOR LI THOUM SECONDARY BATTERY AND METHOD FOR MANUFACTURING THE SAME

摘要

A safe all-solid-state lithium secondary battery using a functionalized Metal-organic framework (MOFs)-based solid-state electrolyte composite and methods for manufacturing that electrolyte are provided. Specifically, that solid-state electrolyte composite includes MOFs material and traditional polymer, which are mixed and electrospining into a solid thin film. The solid-state electrolyte could significantly reduce the safety risk as well as enhance the Li+ conductivity rate through reducing the degree of crystallinity for polymer and coupling the polymer within the oriented and uniform pore structures in MOFs, thus improving the ionic conductivity and enhancing the Li batteries performance. The procedure involves only one step, and it is expected to be easy for scale-up.
