PURPOSE: A composition for preparing an adhesive polymer electrolyte and a secondary battery containing the composition are provided, to improve the stability of a secondary battery without deterioration of the properties of a secondary battery compared with a secondary battery employing a liquid electrolyte. CONSTITUTION: The composition for preparing an adhesive polymer electrolyte comprises 85-99 wt% of a nonaqueous organic solvent containing 0.7-0.9 mol/L of alkali metal salt; 1-15 wt% of an epoxy resin; and 1-15 wt% of an amine monomer. Preferably the nonaqueous organic solvent is selected from the group consisting of propylene carbonate,γ-butyrolactone, ethylene carbonate, dimethyl carbonate, diethyl carbonate, 1,2-dimethoxyethane, tetrahydrofuran, 3-methyloxazolidin-2-one, 2-methyltetrahydrofuran, dimethylsulfoxide, diethylether and acetonitrile. The epoxy resin is epichlorohydrin polyglycol epoxy resin and has a molecular weight of 100-600. The amine monomer is at least one selected from the group consisting of diethylene triamine, dipropylene triamine, triethylene tetramine, dimethylaminopropylamine, hexamethylene diamine and diaminodiphenylsulfone. Preferably the alkali metal salt is lithium salt. |
