PURPOSE:To obtain a battery with improved reversibility of charging and discharging and good cycle life by using an electrolyte containing LiAsF6 and ether solvent. CONSTITUTION:Li salt expressed by LiAsF6+LiX (X is a halogen compound such as BR4, PF6, SbF6, ClO4.) is mixed as the electrolytic material of an electrolyte, and an organic solvent mixed with ether solvent is used as the solvent of the electrolyte. The dendritic deposition of Li and the reaction with the electrolyte is thereby suppressed, the collapse of an electrode due to the volume change at the time of charging and discharging is suppressed for the alloy electrode, and a secondary battery with good charging and discharging reversibility and long cycle life is obtained. |
