Abstract

With the rapid development of electric vehicles and electric communication, the requirement for high-performance lithium-ion batteries(LIBs) has been greatly increased. Copper foil is used as the negative current collector in LIBs, and its performance affects the efficiency, stability, and service life of batteries. To improve the energy density and stability of LIBs, ultra-thin copper foil with higher strength properties and corrosion resistance is urgently needed. However, manufacturing high-performance copper foils remains challenging in industrial production. The nanotwinned copper is considered an ideal material because of its both high tensile strength and superior ductility. The present methods of generating Nt-Cu by pulse electrodeposition and additives assistance cannot meet the needs of stable and efficient industrial production. This study proposes a new DC electrodeposition method conducted at sub-zero temperatures, obtaining high-density Nt-Cu with ideal mechanical properties, which has a tensile strength of 248.12 MPa and an elongation of 26.31 %. Furthermore, the ultra-thin(10 μm) Nt-Cu foils prepared in this study exhibit excellent corrosion resistance, low roughness, and increased fatigue life than normal copper foils electrodeposited at room temperature. This research contributes a valuable idea for the efficient manufacture of copper foils for LIBs.
