PURPOSE:To supply a secondary battery of high output and high energy density by using an extremely thin aluminum foil as a positive pole current collector. CONSTITUTION:The output characteristic of a nonaqueous battery can be improved and such a nonaqueous secondary battery of high output and high energy density can be obtained by using an aluminum foil of 1-100mum in thickness as the current collector of a positive pole 1. To raise energy density, it is desirable that open terminal voltage is 3V or more. However when the open terminal voltage is 5V or more, the electrolytic liquid may state decomposition even if it is in nonaqueous group. Then the open terminal voltage should be less than 5V. |
