The mixing soft-segment WPU (waterborne polyurethane) polymer electrolytes were synthesized by using PEO (poly(ethylene oxide)) and PDMS (polydimethylsiloxane) as the soft segments. These polymer electrolytes exhibit good thermal and electrochemical stability. The conductivity of the gel polymer electrolyte is 2.52×10^-3 S/cm at 25℃ with the LiTFSI/(DMC+EC) content of 130%.
