▎ 摘  要

NOVELTY - Anode comprises a positive current collector, and a structure in which a first mixture layer and a second mixture layer are sequentially stacked. The first mixture layer contains first binder made of rubber-based resin. The second mixture layer contains second binder made of fluorine-based resin derived from fluorine-containing monomer. USE - The anode is useful for lithium secondary battery. ADVANTAGE - The anode is hydrophobic; has improved durability; improves adhesion between cathode current collector and mixture layer, and electrical performance and lifespan of lithium secondary battery; and minimizes damage to cathode additive during cathode manufacturing due to first binder having low affinity for water. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for manufacturing an anode.
