The invention discloses a method to made polyvinylidene fluoride copolymer gel state electrolyte membrane.

The mixture can be rapidly formed into gel state when meeting water, and the adopted auxiliary material and additive are all consistent with the oral intake standard.

Electrolyte: in gel state, no delamination, battery electrolyte circulation performance is good; The electrolyte density low, slow on board gate corrosion, floating battery life is long.
