REINFORCED IONIC CONDUCTING MATERIAL, USE THEREOF IN ELECTRODES AND ELECTROLYTES

摘要

The invention concerns a solid ionic conducting material for use as electrolyte or as component of a composite electrode. The material comprises a polymer matrix, at least one ionic species and at least one reinforcing agent. The polymer matrix is a solvating polymer optionally having a polar character, a non-solvating polymer bearing acid ionic groups, or a mixture of a solvating or non-solvating polymer and an aprotic polar liquid. The ionic species is an ionic compound selected among salts and acids, said compound being in solution in the polymer matrix, or an anionic or cationic ionic group fixed by a covalent bond on the polymer, or a combination of both. The reinforcing agent is a cellulosic material or a chitin.
