A novel polymer electrolyte with high elasticity and high performance for lithium metal batteries.

A polymer electrolyte with high elasticity and high performance is prepared by IN SITU polymerization. The polymer electrolyte is amorphous and has a high ionic conductivity of 7.9 × 10-4 S cm-1 and good elasticity. The discharge capacity of Li/LiFePO4 in the 100th cycle is 133.90 mA h g-1 (0.5C, 25 °C).
