Embodiment 1
[0041] In this embodiment, a method for in-situ preparation of an interpenetrating network structure electrolyte interface layer includes the following steps:
[0042] (1) Preparation of interfacial layer precursor: under the atmosphere of protective gas, first mix 1g of 1-vinyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide salt) (VMImTFSI) and LiTFSI (20mol% ) to mix, then add photoinitiator 2-hydroxyl-2-methylpropiophenone and mix evenly, UV light polymerization to obtain polyionic liquid (PIL), then 2mL 1,3 dioxolane (DOL) and LiPF 6 The initiator is mixed evenly and added to the PIL to make it absorbed to obtain the interface layer precursor gel;
[0043] (2) 200mg of inorganic solid electrolyte Li 10 GeP 2 S 12 Press into a ceramic sheet with a diameter of 12 mm, place the above precursor solution on the surface of the inorganic electrolyte sheet, let it stand at room temperature, pass LiPF 6 Initiated cationic polymerization results in an electrolyte interfa...
