A low temperature output characteristic of a lithium secondary battery is improved. A lithium secondary battery includes a positive electrode sheet, a negative electrode sheet including a negative electrode active material of a carbonaceous material that occludes and releases lithium ions, and a carboxylic acid alkali salt, a positive electrode sheet, and a negative electrode sheet. And a non-aqueous electrolyte 20 that conducts lithium ions. [Selection] Figure 1 |
