Abstract

An electrolytic solution capable of suppressing the battery swollenness and improving the battery characteristics such as the charge and discharge efficiency and a battery using it are provided. A cathode (21) and an anode (22) are layered with an electrolyte layer (24) in between. The electrolyte layer (24) is gelatinous, containing the electrolytic solution and a polymer compound. The electrolytic solution contains a compound having proton scavenging capacity such as hexamethylenetetramine and hexaethylenetetramine. Thereby, a free acid such as hydrofluoric acid is scavenged, and decomposition reaction of the electrolytic solution or the like is prevented.
