  "textContent": "Provided is a battery capable of improving battery characteristics such as cycle characteristics. The battery comprises a spirally wound electrode body including a cathode and an anode spirally wound with a separator in between. The capacity of the anode includes a capacity component by insertion and extraction of light metal and a capacity component by precipitation and dissolution of the light metal, and is represented by the sum of them. The separator is impregnated with an electrolyte solution formed through dissolving a lithium salt in a solvent. As the electrolyte salt, diffuoroÄoxalato-O,O'Ülithium borate, tetrafluoroÄoxalato-O,O'Ülithium phosphate or difluorobisÄoxalato-O,O'Ülithium phosphate is used. By the formation of a stable coating, decomposition of the solvent and a reaction between precipitated lithium metal and the solvent can be prevented.",
