Negative Electrode For Lithium Secondary Battery And Method For Manufacturing Same

Abstract: The present invention relates to a negative electrode for a lithium secondary battery and a method for manufacturing 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 collector, wherein the first negative electrode active layer includes artificial graphite and natural graphite as carbon-based negative electrode active materials, and wherein the adhesion between the negative electrode active layer and the negative electrode collector is enhanced by adjusting the orientation index (O.I1st) of the carbon-based negative electrode active materials contained in the first negative electrode active layer, and the content of the artificial graphite, within a certain range. A secondary battery comprising the negative electrode active layer exhibits an excellent lifespan.
