摘要: In a non-aqueous electrolyte battery using titanium oxide or lithium titanate as a negative electrode material for negative electrode, polymeric electrolyte is interposed between the negative electrode and a positive electrode. If titanium oxide or lithium titanate is used as the negative electrode material for negative electrode and the polymeric electrolyte is interposed between the negative electrode and the positive electrode, the polymeric electrolyte is less liable to be decomposed by catalytic reduction induced by titanium oxide or lithium titanate. This prevents decline in the charge/discharge efficiency which occurs when a non-aqueous electrolyte solution is used. Thus, the non-aqueous electrolyte battery excellent in charge/discharge efficiency is provided.
