PROBLEM TO BE SOLVED: To obtain the subject composition excellent in film forming properties, adhesiveness to an electrode and ion electroconductivity when used together with a lithium compound and useful for film cells, etc., by mixing a specific monomer, methylenebisacrylamide, lithium compound and its solvent. SOLUTION: This composition capable of forming a solid electrolyte preferably comprises (A) 100 pts.wt. of a monomer having (meth)acryloyl and acetoxy groups [e.g. acetoxyethyl (meth)acrylate], (B) 0.1-50 pts.wt. of an unsaturated urethane obtained by reacting an unsaturated polyester having (meth)acryloyl and OH groups in a molecule with an isocyanate compound, (C) 1-50 pts.wt. of a lithium compound such as lithium perchlorate, lithium tetrafluoroborate, lithium hexafluorophosphate, based on 100 pts.wt. of the sum total of the components A+B+C and (D) 10-500 pts.wt. of a solvent capable of dissolving the component C. |
