Embodiment 160
[0018] Example 1 Preparation of polymer electrolyte with 60% lithium salt addition
[0019] Add 2 g of polyvinyl carbonate and 40 g of acetonitrile into a 100 ml reagent bottle and stir at room temperature for 6 h to obtain a homogeneous solution. Add 3 g of lithium bistrifluoromethanesulfonimide to the above solution and stir at room temperature for 6 h. After completely dissolving, a uniform mixed solution is obtained, and the mixed solution is injected into a polytetrafluoroethylene (PTFE) mold to dry to form a film, and vacuum dried to obtain a solid polymer electrolyte membrane.
Embodiment 2
[0020] Example 2 Adding SiO 2 Preparation of polymer electrolyte with 73% lithium salt addition
[0021] 1 g polyvinyl carbonate, 0.5 g SiO 2 (15 nm) and 40 g of acetonitrile were added to a 100 ml reagent bottle and stirred at room temperature for 6 h to obtain a homogeneous solution. Add 4 g of lithium bistrifluoromethanesulfonyl imide to the above solution and stir at room temperature for 6 h. After completely dissolving Obtain a uniform mixed solution, inject the mixed solution into a PTFE mold, dry it to form a film, and dry it in vacuum to obtain a solid polymer electrolyte membrane.
Embodiment 380
[0022] Example 3 Preparation of 80% Lithium Salt Addition Polymer Electrolyte
[0023] Add 1 g of polyvinyl carbonate and 40 g of acetonitrile into a 100 ml reagent bottle and stir at room temperature for 6 h to obtain a homogeneous solution. Add 4 g of lithium bistrifluoromethanesulfonimide to the above solution, and stir at room temperature for 6 h. After completely dissolving, a uniform mixed solution is obtained, and the mixed solution is injected into a polytetrafluoroethylene (PTFE) mold to dry to form a film, and vacuum dried to obtain a solid polymer electrolyte membrane.
