Abstract
The invention relates to polymer compositions that conduct lithium ions including the following ingredients: at least one ionic polymer from the polymerization of an ionic liquid, the cation of which bears at least one polymerizable function; at least one lithium salt; and at least one non-ionic polymer, the composition being a solid composition, i.e., a composition devoid of water and organic solvent(s). The invention also relates to the use of the polymer compositions for entering into the formation of electrolytic membranes of electrochemical lithium generators.
