Negative Electrode And Secondary Battery Comprising Same

Abstract: The present invention relates to a negative electrode comprising: a negative electrode current collector; a lower negative electrode active material layer disposed on the negative electrode current collector; and an upper negative electrode active material layer disposed on the lower negative electrode active material, wherein the lower negative electrode active material layer comprises a first negative electrode active material including natural graphite particles and a second negative electrode active material including artificial graphite particles in a primary particle form, the upper negative active material layer comprises a third negative electrode active material including artificial graphite particles in a secondary particle form where two or more primary particles are assembled, and the first negative electrode active material has a pore volume of 0.06mL/g or less as measured by a mercury porosimetry method.
