Positive electrode active material, electrochemical device, and electronic device |
| abstract |
A positive electrode active material, including: a secondary particle formed from a primary particle. The secondary particle includes an inner part and an outer part that wraps the inner part. A ratio of an average particle size of primary particles in the outer part to an average particle size of primary particles in the inner part is G, and 1.1 ≤ G ≤10. The outer part is a region from an interface of the secondary particle to a surface of the secondary particle, and the inner part is a region from the interface of the secondary particle to a center of the secondary particle. The positive electrode active material in this disclosure improves cycle performance while ensuring good rate performance. |
