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 con-ductivity of 4.02 × 10-4 S/cm at 60 ℃.DFT calculations were used to visualize the possible diffusion path-way of Li+.The all-solid-state cell assembled with LiFePO4,composite polymer electrolyte and lithium metal foil delivered with excellent cycling capability and stability even under high current densities.
