Abstract

The present disclosure relates to a negative electrode for a lithium secondary battery and a method of manufacturing the same. The negative electrode satisfies a ratio of porosity to orientation index (O.I.) of a carbon-based negative electrode active material within a predetermined range, thereby shortening the movement path of lithium ions in a negative electrode active layer and significantly lowering diffusion resistance of lithium ions, thereby the rapid charging performance of the negative electrode is excellent. In addition, the negative electrode has an advantage of excellent energy density of the negative electrode because the density of the negative electrode active layer is improved within a range that does not damage the shortened movement path of lithium ions.
