Negative Electrode For Lithium Secondary Battery And Method Of Manufacturing Same

Abstract: The present invention relates to a negative electrode for a lithium secondary battery and a method of manufacturing same. The method of manufacturing a negative electrode comprises drying a negative electrode slurry to which a magnetic field is applied and then rolling the dried negative electrode slurry, and controlling the rolling load according to equation 1, which depends on the strength of the magnetic field applied to the negative electrode slurry, and thus, significantly alleviates the spring-back of a negative electrode active layer even through simple and fewer processes , thereby achieving excellent process efficiency and economic efficiency. In addition, the manufactured negative electrode exhibits high energy density while maintaining the target thickness and reduces charging/discharging-related volume change of the negative electrode active layer due to the low rolling stress and the improved structural stability of the negative electrode active layer, thereby advantageously improving the lifespan thereof.
