Abstract
A negative electrode active material is granular, and the negative electrode active material includes first particles and second particles, where a sphericity of the first particles is greater than a sphericity of the second particles, the sphericity of the first particles is 0.6 to 1.0, and a particle size D<sub>v</sub>50 of the first particles is smaller than a particle size D<sub>v</sub>50 of the second particles. Applying the negative electrode active material of this application to a secondary battery can increase a compacted density of a battery electrode plate, thereby increasing the energy density of the secondary battery while improving the cycling performance of the secondary battery.
