In a non-aqueous electrolyte battery including a positive electrode using an active material containing Mn and propylene carbonate as a solvent, the deterioration of the positive electrode is prevented, and gas generation due to decomposition of the electrolyte solution on the positive electrode side is reduced. Reduce resistance. An active material containing Mn, for example, a lithium-containing manganese oxide, a positive electrode using a composite oxide in which a part of manganese of the lithium-containing manganese oxide is substituted with another element, and a non-propylene carbonate as a solvent. Vinyl ethylene carbonate, 1,3-butadiene ethylene carbonate, divinyl ethylene carbonate, or the like is added to the water electrolyte battery. [Selection] Figure 1 |
