Abstract
A negative electrode includes silicon-based particles and graphite particles, where a quantity of graphite particles present within a vertical distance of about 0 to 6 μm to respective edges of the silicon-based particles is N, and based on a total quantity of the silicon-based particles, more than about 50% of the silicon-based particles satisfy: 6≤N≤17. The negative electrode has good cycle performance, and a battery prepared by using the negative electrode has good rate performance and a low deformation rate.
