Characterization of Cold-Rolled Nickel Electroplated Copper Sheet

The electroplating of nickel on the copper sheet for lead tap, which is one of the important parts of the secondary battery, has been conducted to improve functional properties such as electrical, thermal and mechanical properties. Materials used for secondary battery parts were known manufactured as cladding methods with different kind metal bonding by cold-roll process. In this study, the nickel was electroplated on the copper sheet and cold rolled and heat treated to evaluate the functional properties and to determinate the grain growth orientation and to investigate the texture formation. Grain growth direction and texture formation were analyzed by the X-ray pole figure. The influence of texture on the mechanical properties could be quantitatively confirmed by the results from the orientation distribution function and the tensile test. The heat-treated textures of the cold-rolled hybrid copper sheet were also investigated.
