ABSTRACT:
The invention is to obtain a polymer solid electrolyte composition which is free from electronic conduction and which has a high ionic conductivity even at temperatures near to room temperature and has good film-forming properties, mechanical strength and flexibility. The composition comprises an organic polymer having an alkyl quaternary ammonium salt structure, a nitrogen-containing, heterocyclic quaternary ammonium salt and a metal salt. The organic polymer preferably has an alkyl quaternary ammonium salt structure at the end of the side chain of the polymer or in the main chain thereof, such as polydimethylaminoethyl methacrylate methyl chloride quaternary salt, polydimethylaminopropylmethacrylamido methyl chloride quaternary salt, poly(N,N-dimethyl-3-pyrrolinium chloride), etc. The nitrogen-containing, heterocyclic quaternary ammonium salt (e.g., alkylpyridinium halides) and the metal salt (e.g., aluminium halides) form a cold-melting salt.
