Embodiment 1
[0018] Example 1: 12 g of N-vinyl-N-ethylimidazole bromide and 13.71 mL of ethylene were dissolved in 60 mL of chloroform; a mixture of 0.183 g of azobisisobutyronitrile and potassium persulfate was added to the solution In the medium, quickly install the condenser tube, feed nitrogen gas, stir and react at 65 °C for 5 h, then filter to obtain a polymer gel electrolyte, wash it with chloroform several times, and dry it in vacuum at 80 °C for later use; The gel electrolyte is dissolved in methanol, stirred until uniform, cast on a polytetrafluoroethylene plate, and dried to obtain a polymer gel electrolyte membrane 1 .
Embodiment 2
[0019] Example 2: Dissolve 12 g of N-vinyl-N-ethylimidazole bromide and 3.26 mL of methyl methacrylate and 1.37 mL of ethylene in 60 mL of chloroform; then add 0.0789 g of azobisisoheptanonitrile to In this solution, a condenser tube was quickly installed, and argon gas was introduced, stirred and reacted at 70 °C for 5 h, and then filtered to obtain a polymer gel electrolyte, which was washed several times with chloroform, and vacuum-dried at 80 °C for later use; then the obtained The polymer gel electrolyte is dissolved in methanol, stirred until uniform, cast on a polytetrafluoroethylene plate, and dried to obtain the polymer gel electrolyte membrane 2 .
Embodiment 3
[0020] Example 3: 12 g of N-vinyl-N-propylimidazolium boron tetrafluoride and 1.68 mL of vinylidene fluoride were dissolved in 60 mL of carbon tetrachloride; 0.0651 g of benzoyl peroxide was added to the solution In the medium, quickly install the condenser tube, pass in argon, stir and react at 80 °C for 3 h, then filter to obtain a polymer gel electrolyte, wash it with carbon tetrachloride several times, and dry it in vacuum at 80 °C for later use; The polymer gel electrolyte was dissolved in DMF, stirred until uniform, cast on a polytetrafluoroethylene plate, and dried to obtain the polymer gel electrolyte membrane 3 .
