PROBLEM TO BE SOLVED: To provide a secondary battery, in which the deterioration of characteristic due to the swelling of the binder to be used for forming electrodes, which can store and discharge alkali metal ions, by the solvent for the electrolyte is restricted. SOLUTION: Electrode material of any one or both of a negative and a positive electrodes, which are arranged in both sides of the electrolyte and which can store and discharge alkali metal ions, are connected by the complex binder of fluorine high molecular compound and high molecular compound having polysaccharide skeleton. |
