Patent number: RE44705Abstract: A battery capable of improving the storage characteristics and the cycle characteristics is provided. The battery includes a cathode, an anode, and an electrolytic solution. The electrolytic solution is impregnated in a separator provided between the cathode and the anode. A solvent of the electrolytic solution contains a given sulfone compound such as bis(trimethylsilyl)-2,2-difluorosulfoacetate. Compared to a case that a solvent does not contain the foregoing sulfone compound, the chemical stability of the electrolytic solution is improved, and the decomposition reaction of the electrolytic solution is suppressed.Type: GrantFiled: February 1, 2013Date of Patent: January 14, 2014Assignee: Sony CorporationInventors: Masayuki Ihara, Hiroyuki Yamaguchi, Tadahiko Kubota
