Zusammenfassung:PURPOSE:To obtain a high-polymeric solid electrolyte thin film with thickness of 50mum or less and area of 30cm or more by forming it from high-polymeric solid electrolyte monomer made by mans of mixing and dissolving the appropriate quantity of inorganic alkaline salt to the specific macromer-monomer. CONSTITUTION:A high-polymeric solid electrolyte thin film is formed from high-polymeric solid electrolyte monomer made by means of mixing and dissolv ing the appropriate quantity of inorganic alkaline salt such as LiClO4, LiBF4, LiSCN, NaClO4, NaPF6, NaSCN, etc. to the macromer-monomer as showen in the expression 1. In this expression 1, a+b=3, a>0 and besided b>=1, R1=H, CH3, C2H5, R2=C2H4, C3H6, PEG is polyethyleneglycolmonomethylether, Mw=200-700, PPC is polypropyleneglycolmonoethylether, Mw=250-900. Thus, the high performance high-polymeric solid electrolyte thin film with thickness of 50mum or less and area of 30 cm or more can be made by relatively simple method.
