PROBLEM TO BE SOLVED: To improve the conductivity of a positive electrode. SOLUTION: This secondary battery has a positive electrode, containing carbon black, nonfibrous graphite particle and fibrous carbon, is equipped with a negative electrode composed mainly of a carbon material capable of storing/ emitting, for example, lithium, the positive electrode composed mainly of a transition metal multiple oxide, and an electrolytic solution made by dissolving an electrolyte of a lithium salt in a nonaqueous solvent. The positive electrode contains acetylene black, flake graphite, vapor phase epitaxy fibrous graphite, and a binder. |
