A solid, polymeric electrolyte is constituted by a solid solution of an ionic compound in a polyepoxide, wherein said polyepoxide is the product of copolymerization of a monoepoxide of formula: <CHEM> wherein: R stands for methyl or ethyl radical; and n is an integer comprised within the range of from 2 to 10; with a diepoxide of formula: <CHEM> wherein: m is an integer comprised within the range of from 2 to 10; with a molar ratio of monoepoxide to diepoxide comprised within the range of from 99.9/0.1 to 90/10; with said polyepoxide furthermore having a weight average molecular weight equal to, or higher than, 1,000, and a glass transition temperature (Tg) of from -80 to -60 DEG C. The solid, polymeric electrolyte can be converted into an electrochemical membrane useful in the manufacture of high-energy-density electrochemical generators, optical displays, electrochromic systems and sensors. |
