Negative electrode for lithium secondary battery and lithium secondary battery comprising the same

Abstract

Negative electrodes for lithium secondary batteries and lithium secondary batteries including the negative electrodes are disclosed. In some implementations, a negative electrode for a secondary battery includes a negative electrode current collector, a first negative electrode mixture layer including a first silicon-based negative electrode active material and disposed on at least one surface of the negative electrode current collector, and a second negative electrode mixture layer including a second silicon-based negative electrode active material and disposed on the first negative electrode mixture layer, wherein the second silicon-based negative electrode active material is SiOx (0≤x<2) doped with a metal element.

Dependencies are inferred from the claim text.
