PROBLEM TO BE SOLVED: To obtain a composition capable of forming a handleable gel electrolyte, even when containing a large amount of a solvent, compatible with lithium compounds, not depositing a lithium electrolyte dissolved in a solvent, capable of forming a crosslinked structure and capable of forming a soiled electrolyte. SOLUTION: This composition capable of forming a solid electrolyte comprises 100 pts.wt. of an unsaturated cellulose derivative obtained by reacting 1 mole of the residual hydroxyl group of a cellulose ester derivative with 0.01-1 mole of the isocyanate group of an unsaturated monoisocyanate, 10-100 pts.wt. of (meth)acrylonitrile, a lithium compound in an amount of 1-50 pts.wt. per 100 pts.wt. of the total amount of the unsaturated cellulose derivative and the (meth)acrylonitrile, and 10-1000 pts.wt. of a solvent. |
