As one of the main components of the battery, copper foil is used to manufacture the battery&#8217;s electrodes. Its excellent conductivity and mechanical properties make copper foil an ideal material for battery production. In the battery production process, copper foil serves as the support substrate for the electrode, providing good electrical conductivity and mechanical strength, while also ensuring the stability and long-term performance of the battery. Therefore, copper foil plays an irreplaceable role in battery manufacturing, with significant effects on battery performance and lifespan.<\/p>\n<p><b><strong>Note: The copper foil surface can be coated by carbon, cathode materials, e.g. LiFePO4, LiCoO2, upon request.<\/strong><\/b><\/p>\n<p><b><strong>Spot Copper Foil Size<\/strong><\/b><\/p>\n<table>\n<tbody>\n<tr>\n<td
