| titleOfInvention | Negative electrode for secondary battery and secondary battery comprising the same |
| abstract | The present invention includes a current collector, a first negative electrode active material layer positioned on the current collector, and a second negative electrode active material layer positioned on the first negative electrode active material layer, wherein the first negative electrode active material layer and the second negative electrode active material Each layer independently includes a negative electrode active material, a styrene-butadiene rubber binder and a cellulose compound, and the first negative electrode active material layer includes a styrene-butadiene rubber binder in a higher content than the second negative electrode active material layer, In addition, the cellulose-based compound included in the first cathode active material layer provides a negative electrode for a secondary battery having a lower degree of substitution of a carboxyl group in a structural unit and a secondary battery including the same, compared to the cellulose-based compound included in the second anode active material layer. The negative electrode for the secondary battery includes two layers of active material having an optimized composition according to the position of the negative electrode active material layer, thereby improving adhesion between the negative electrode active material layer and the current collector, and as a result, capacity characteristics, life characteristics and output characteristics of the battery. Can greatly improve. |
