摘要： A secondary battery capable of safely improving a battery performance is provided. An electrolyte with which a separator 13 is impregnated contains an alkyl sulfone and a low-polar solvent (a solvent having a relative permittivity of 20 or less) together with an aluminum salt. The alkyl sulfone facilitates the redox reaction of aluminum, and further reduces the reactivity of the electrolyte. Additionally, the low-polar solvent suppresses the block of the redox reaction of aluminum. In charge and discharge, it becomes easy to electrochemically efficiently precipitate and dissolve aluminum, and further to inhibit the corrosion of a metallic exterior package member or the like.
