ANODE FOR SECONDARY BATTERY AND SECONDARY BATTERY HAVING THE SAME

摘要

PURPOSE: A negative electrode for a secondary battery is provided to have excellent resistance to internal stress and pressure and to have excellent electrochemical reactivity by including a multilayered active material layer. CONSTITUTION: A negative electrode(100) for a secondary battery comprises a wire type current collector(110); a metallic negative electrode active material which includes a metallic negative electrode active material and is formed on the surface of the wire type current collector; a graphite-based negative electrode mixture layer(130) which is formed on the surface of the metallic negative electrode active material layer and comprises a mixture of graphite-based active material, conducting material, and a first binder; and a conducting layer which surrounds the outer side of the graphite-based negative electrode mixture layer and comprises a mixture of a second polymer binder and carbon particle. The secondary battery comprises the positive electrode, negative electrode, and a separating layer.
