(57) [Summary] [PROBLEMS] To provide a high capacity non-aqueous secondary battery. SOLUTION: A positive electrode sheet containing a positive electrode active material mainly composed of a lithium-containing transition metal composite oxide, a negative electrode sheet containing a carbon material capable of occluding and releasing lithium, and a nonaqueous electrolyte having a nonaqueous electrolyte containing a lithium salt In the secondary battery, a negative electrode sheet having a structure in which a metal foil mainly composed of lithium is pasted through an auxiliary layer and a non-aqueous electrolyte containing an aromatic compound as an additive are used. |
