Abstract
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.
