PROBLEM TO BE SOLVED: To increase capacity while excellent cycle characteristics are ensured. SOLUTION: In a nonaqueous electrolyte secondary battery using composite oxide of lithium and transition metal as a positive active material, a carbonaceous material capable of doping/undoping lithium in a negative electrode, and containing a binder in a positive electrode and the negative electrode, as the binder, a mixture of a fluorine base polymer and nitrile rubber or hydrogenated nitrile rubber is used. This binder can be used in the positive electrode and the negative electrode. |
