Negative Electrode Active Material, And Negative Electrode And Secondary Battery Comprising Same

Abstract: The present invention relates to a negative electrode active material comprising artificial graphite particles, wherein, when a sample comprising the negative electrode active material and water is measured with a torque rheometer, the solid content value of the negative electrode active material is at least 69.5 wt% when the sample being measured through a specific method is at the maximum torque value. If the solid content value at the maximum torque value when the torque rheometer measurement is performed satisfies the range, then the powder flowability of the negative electrode active material can be evaluated to be excellent, and if the negative electrode active material is included in a negative electrode slurry, then dispersibility and phase stability can be improved. Therefore, a negative electrode slurry comprising the negative electrode active material of the present invention, and a negative electrode and a secondary battery manufactured therefrom can be improved in productivity and quality.
