The demand for high density energy storage devices in electronic products is increasing. The application of various wearable devices in medical treatment, health management is also gradually emerging, which also requires high-performance power storage components. Recently, we have successfully electroplated nanotwinned copper foils with a titanium wheel setup, and their ultimate tensile strength can reach to over 800 MPa, while maintain an acceptable ductility. The conductivity of nanotwinned copper foil can reach more than 90% IACS (International Annealing Copper Standard). Nanotwinned copper foil with high mechanical strength and conductivity not only enhance the weight energy density and volume energy density of the battery, it also solves the reliability issue during the charge and discharge cycles.
