We investigated an electrodeposition technique for fabricating a high-strength thin metallic foil as a current collector materialin secondary batteries. To increase the strength and minimize the increase in electrical resistivity, copper–nickel (Cu–Ni)double-layered foils were considered and the grain structures of each layer were manipulated by controlling the electrodepositionsolution and process conditions. Initially, a Cu electrodeposition process was developed to form a bamboo-like grainstructure after annealing, which was followed by two Ni processes to produce a foil with a columnar or nano-crystallinegrain structure. Subsequently, several foils were annealed at 190 °C for 10 min considering that current collectors experiencea thermal load during battery manufacturing. Scanning and transmission electron microscopy-based crystallographicorientation mapping techniques indicated a remarkable change in the grain structure of the Cu foil owing to the grain growthafter annealing; conversely, the Ni foil with the nano-crystalline grain structure was insensitive to annealing. By applyingthese processes to each material, four 10-μm-thick double-layered foils were fabricated. Among these foils, the foil with anano-crystalline Ni layer exhibited the smallest change in material properties resulting in the highest tensile strength andmoderate elongation after annealing. The tensile strength of the best double-layered foil was approximately three-fold higherthan that of the single-layered Cu foil after annealing.
