COPPER FOIL FOR CURRENT COLLECTOR OF LITHIUM SECONDARY BATTERY

摘要

PURPOSE: A copper foil for a current collector of a lithium secondary battery is provided to secure excellent adhesion in contact with a negative active material such as carbonaceous slurry. CONSTITUTION: A copper foil(100) for a current collector of a lithium secondary battery has a matte side as one side thereof and includes a nodule cluster(101) with 0.001~2 aspect ratio between nodules, wherein a water contact angle is 90 ° or less. A ratio of a texture coefficient of (200) plane to the sum of texture coefficients of (111) plane and (200) plane is 30~80%.
