Embodiment 1
[0030] Mix and stir 2.8g HDI trimer, 0.5PEG (Mw=1000), 2.8g nano-alumina, 4ml acetonitrile and tetraethylene glycol dimethyl ether (TEGDME) (V:V=1:1); add 1g lithium hexafluorophosphate ( LiPF 6 ) were mixed evenly to prepare a transparent and clear electrolyte; 0.1g of dibutyltin dilaurate was added dropwise and stirred evenly; the evenly stirred composite polymer electrolyte was scraped onto a polytetrafluoroethylene mold, and heated to 60°C in a glove box , Cured for 12 hours to form a film.
Embodiment 2
[0032] 2.2g HDI trimer, 0.5PEG (Mw=1500), 2g Li 10 GeP 2 S 12 , 4ml tetraethylene glycol dimethyl ether (TEGDME) and 1-methyl-2 pyrrolidone (V:V=1:1) are evenly mixed and stirred; add 0.8g LiN(C 2 f 5 SO 2 ) 2 Mix evenly to prepare a transparent and clear electrolyte; dropwise add 0.12g of dibutyltin dilaurate and stir evenly; scrape the evenly stirred composite polymer electrolyte onto a polytetrafluoroethylene mold, heat it to 60°C in a glove box, and cure 12 hours film formation.
Embodiment 3
[0034] 2.5g HDI, 4g EG, 1g Li 10 GeP 2 S 12 Mix and stir with 2ml tetraethylene glycol dimethyl ether; add 2g LiBOB and mix evenly to prepare a transparent and clear electrolyte; dropwise add 0.06g bis(acetylacetonate) dibutyltin and stir evenly; scrape the evenly stirred composite polymer electrolyte Put it on a polytetrafluoroethylene mold, heat it to 60°C in a glove box, and cure it for 12 hours to form a film.
