▎ 摘  要

NOVELTY - A surface-modified zinc-manganese dioxide secondary battery negative electrode comprises a metal layer comprising zinc, and a surface coating layer formed on one surface of the metal layer. USE - Surface-treated negative electrode is used for zinc-manganese dioxide secondary battery (claimed) used as power source for various electric and electromechanical devices ranging from domestic electronic devices to fuel cells for next-generation electric vehicles. ADVANTAGE - The anode suppresses growth of dendrite on surface of anode through surface treatment of the anode, reduces interfacial resistance of the electrode, lowers reactive overvoltage, and improves service life of the battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for surface modification of negative electrode, which involves forming a coating layer (a1) by immersing metal layer containing zinc in a coating solution, and reducing the layer (a1) to form surface coating layer.
