COPPER FOIL FOR BATTERY AND METHOD OF MANUFACTURING FOR COPPER FOIL FOR BATTERY

Document Type and Number:

Japanese Patent JP2003197199

Kind Code:

A

Abstract:

To provide a copper foil for a battery possessing both elongation and strength having the elongation even before heat treatment and keeping the strength even after heat treatment.

Percentage of mass of 0.015-0.04 or more of phosphorus and percentage of mass of 0.01-0.15 or more of at least one component of iron, cobalt, and nickel in the total amount are added to a copper material, the mixed material is rolled to form the copper foil, and the obtained copper foil is heat treated. The copper foil is used in a positive electrode 1 or a negative electrode 2.
