Negative Electrode, And Secondary Battery Comprising Same

Abstract: The present invention relates to a negative electrode comprising a negative electrode current collector, and a negative electrode active material layer disposed on the negative electrode current collector, wherein the negative electrode active material layer includes a silicon-based active material, a first conductive material including graphite, a second conductive material including single-walled carbon nanotubes, and a binder. The binder includes a cellulose-based compound and a rubber-based compound. The negative electrode active material layer contains 15 wt% to 25 wt% of the first conductive material and 0.15 wt% to 2.5 wt% of the second conductive material. The weight ratio of the second conductive material and the binder in the negative electrode active material layer is 1.5:99.5 to 20.0:80.0.
