▎ 摘　　要

NOVELTY - Method for manufacturing a surface-patterned current collector comprises etching and patterning the current collector and coating a carbon material on the patterned current collector. The patterning of the current collector by etching comprises electrochemical etching, where etching solution used for electrochemical etching is hydrochloric acid, phosphoric acid, sulfuric acid, nitric acid, acetic acid, carbonic acid, trifluoroacetic acid, oxalic acid, hydrofluoric acid, boric acid, perchloric acid or hypochlorous acid. USE - The method is useful for manufacturing surface-patterned current collector. ADVANTAGE - The method forms anti-oxidation film; improves the stability of the electrode by improving the specific surface area of the current collector by patterning the current collector through electrochemical etching; achieves fine pattern of the current collector; reduces interface resistance by coating thinly and uniformly even on the surface; and improves excellent physical/chemical stability of the current collector. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for surface-patterned current collector manufactured by above method.
