Traditional copper foil used as an anode current collector is prone to corrosion, and while materials such as SUS and Ni have been used as
alternatives due to their corrosion resistance, they have limitations in terms of cost efficiency and compatibility with existing processes.
LOTTE Energy Materials' nickel-plated copper foil addresses these issues, offering excellent heat resistance and corrosion resistance,
thereby maximizing the performance of all-solid-state batteries. Additionally, the nickel-plated copper foil meets requirements such as zero
pinholes, defect-free, low roughness, specific tensile strength, and elongation, making it an important material in the so-called "dream
battery," the all-solid-state battery. Thanks to these characteristics, nickel-plated copper foil significantly enhances the stability and
performance of all-solid-state batteries and is recognized as a key material for next-generation energy storage solutions. LDN is a key material designed for next-generation all-solid-state batteries. It is a product with nickel plating on conventional copper foil.
