PURPOSE:To obtain solid electrolyte having excellent ionic conductivity by hardening and a molding a composition consisting of a specific acryloyl denaturated polyethylene oxide, inorganic ionic salt and polyethylene oxide having a specific molecular weight. CONSTITUTION:A composition consisting of acryloyl denaturated polyalkylene oxide presented by a formula I, inorganic ionic salt and 10000MW or more of macromolecular polyethylene oxide is hardened. In the formula I, R represents hydrogen or a lower alkyl radical. The acryloyl denaturated polyalkylene oxide is a compound in which an ethylene glycol structure such as triethylene glycol monoacrylate is replaced with a propylene glycol structure or a copolymerization structure with an arbitrary ratio of ethylene oxide to propylene oxide. As the inorganic ionic salt herein, such inorganic ionic salt as to include one kind of Li, Na, K, Cs, Ag, Cu and Mg can be employed. As a result, it is possible to obtain solid electrolyte having high ionic conductivity, excellent moldability and superior mechanical property. |
