SOLID ELECTROLYTE COMPOSITION

The present invention relates to a solid electrolyte composition comprising: —[CH(J)CHO][CHCH(J)O]—H (I) wherein each J is independently H, aryl, straight or branched alkyl, and na and na′, equal to or different from each other, are zero or an integer from 1 to 50, with the proviso that na+na′ is from 1 to 50; R—[OCHR(CH)CHR]—OR (II) wherein each of Rand Ris independently a hydrogen atom or a C-Calkyl group, j is zero or an integer of 1 to 2, Rand Ris independently a hydrogen atom or a C-Calkyl group, and n is an integer from 5 to 1000, and
