Abstract
An organic solid electrolyte comprises a polymer obtained by (co)polymerization of cyanoethyl acrylate and/or cyanoethyl methacrylate, the polymer being doped with an inorganic ion salt. The electrolyte has a high ionic conductivity and is based on a hydroxyl-free polymer so that it may be used to construct a secondary battery which eliminates the risk of gas evolution.
