  • Publication number: 20250112262
    Abstract: Disclosed herein relates to a negative electrode for lithium secondary battery and a method for manufacturing the same. The negative electrode has a structure in which a first negative electrode active layer and a second negative electrode active layer are sequentially stacked on a negative electrode current collector. By controlling alignment (O.I) of the carbon-based active material to be lower in the second negative electrode active layer than in the first negative electrode active layer, and by preparing a low percentage of pores in the second negative electrode active layer, it is possible to have a flow path for the electrolyte to move inside the negative electrode active layer even after the rolling process of the negative electrode active layer. The negative electrode also has a high wetting ability to the electrolyte and high energy density.
