A particle size distribution A of the negative active material is (D90-D10)/D50. a defect degree B of the negative active material is ID/IG. A ratio of the particle size distribution A of the negative active material to the defect degree B of the negative active material is 6.0≤A/B≤7.2. By controlling the ratio of the particle size distribution A of the negative active material to the defect degree B of the negative active material within the above range, cycle performance and storage performance of the battery can be significantly improved.",
