摘　　要：The composite polymer electrolyte has been obtained via incorporating LiCUST-701(a new metal–organic rotaxane framework modified by Li+)into poly(ethylene oxide)(PEO)matrix and give a high ionic conductivity of 4.02×10^(−4)S/cm at 60℃.DFT calculations were used to visualize the possible diffusion pathway of Li+.The all-solid-state cell assembled with LiFePO_(4),composite polymer electrolyte and lithium metal foil delivered with excellent cycling capability and stability even under high current densities.
