The present invention relates to ionically conductive polymeric materials, to their preparation and to their use as a solid electrolyte. The materials comprise a solid solution of one or more salts in a polymer and are characterized in that the transport and the mobility of a metal cation M.sup.n+ which has the valency n, 1.ltoreq.n.ltoreq.5, are provided by at least one complex anion, corresponding to the general formula [MZ.sub.n Y.sub.p ].sup.p- formed between an anionic ligand Z.sup.-, an anionic ligand Y.sup.- and the cation M.sup.n+, with 1.ltoreq.p.ltoreq.3. Application to the formation of electrochemical generators and of electrochemical systems which make it possible to affect the transmission of light.
Ionically conductive material comprising a solid solution of one or more salts in a polymer, characterized in that the polymer has a framework wherein the solvating units contain at least one heteroatom selected from the group consisting of O, N, F, and S, and that the transport and the mobility of a metal cation M.sup.n+ which has the valency n are provided by at least one complex anion corresponding to the general formula (MZ.sub.n Y.sub.p).sup.p-, wherein M is the same metal in M.sup.n+, formed between an anionic ligand Z.sup.-, an anionic ligand Y.sup.- and the cation M.sup.n+, and wherein 1.ltoreq.n.ltoreq.5, and 1.ltoreq.p.ltoreq.3.
