Hierarchical porous metal-organic framework composite with inorganic fillers for high-performance Li+ ions transport

Abstract

A quasi-solid-state electrolyte (QSSE) based on the hierarchical porous metal-organic framework (MOF) materials mixed with inorganic fillers Zeolite Socony Mobil-5 (ZSM-5) have been prepared for application of lithium ion battery, exhibiting effective storage and transportation capacity for lithium ions. The as-prepared lithium ion transports material demonstrated high ion conductivity (σ = 1.51 ×10−3 S/cm) and Li+ transference number (tLi+ = 0.80). Additionally, the electrolyte displays a wide electrochemical window with excellent electrochemical stability. Importantly, the lithium ion battery of LiFePO4 as the cathode has excellent rate capability and cycle durability, showing a new prospect of high-performance lithium-ion batteries.
