Disclosed is an electrolyte capable of obtaining an excellent quality of electrolyte, and a battery using the electrolyte. A battery device in which a positive electrode and a negative electrode are stacked with a separator being interposed therebetween is enclosed inside an exterior member. The separator is impregnated with an electrolyte. The electrolyte contains a high polymer, a plasticizer, a lithium and at least either carboxylic acid or carboxylate. Therefore, when preparing a high polymer by means of polymerization of monomers, the polymerization of monomers can be smoothly processed even if there is a factor for inhibiting reaction such as copper. As a result, the amount of non-reacted monomers remained in the electrolyte can be suppressed to be extremely small. Therefore, decomposition and reaction of monomers are suppressed even after repeating charging/discharging, so that the deterioration in the charging/discharging efficiency and the charging/discharging characteristic can be prevented. <IMAGE> |
