PROBLEM TO BE SOLVED: To provide a new nonaqueous electrolytic secondary battery with high voltage, high energy density, excellent charge/discharge characteristics, and long cycle life. SOLUTION: In a nonaqueous electrolytic secondary battery constituted with at least a positive electrode, a negative electrode both capable of absorbing/ releasing a lithium ion, and a lithium ion conductive nonaqueous electrolyte, a conductive layer using carbon as a conductive filler is arranged between the electrode mix of the positive electrode 13 and/or the negative electrode 23 and current collectors 11, 21. The internal resistance of the battery is decreased, drop in the capacity and working voltage in high rate discharge is suppressed, and the secondary battery with long cycle life can be obtained. |
