Abstract:
The invention relates to a method of manufacturing a separating membrane in gel form, for an alkali metal ion battery, the method consisting of extruding a mix comprising: an alkali metal salt, a dinitrile compound with formula N≡C—R—C≡N, in which R is a hydrocarbon group CnH2n, and n is equal to 1 or 2 and preferably equal to 2, a hot melt support polymer, soluble in the dinitrile compound.
