ABSTRACT:
A cross-linked polymer solid electrolyte of a polyether having amine functions cross-linked by a curing compound including two epoxy functions, and thereby defining a three-dimensional lattice which complexes an ionizable salt of the formula M.sup.+ X.sup.-, where M.sup.+ is selected from Li.sup.+, Na.sup.+, K.sup.+, Ca.sup.2+, and NH.sup.4+, and X.sup.- is selected from ClO.sub.4.sup.-, CF.sub.3 SO.sub.3.sup.-, SCN.sup.-, BF.sub.4.sup.-, I.sup.-, Br.sup.-, N.sub.3.sup.-, BH.sub.4.sup.-, CF.sub.3 CO.sub.3.sup.-, AsF.sub.6.sup.-, and PF.sub.6.sup.-, the proportion by weight of salt in the electrolyte lying in the range 5% to 40%.
