The EVOH fibers with certain porosity were prepared by electrospinning, and then soaked in lithium sulfonate solution to obtain PU composite polymer electrolyte through chemical cross-linking. The test found that the electrical and mechanical properties of the electrolyte were better than other commonly used polymer electrolytes. It is expected that this type of electrolyte will be widely used in lithium-ion batteries and supercapacitors.
