Abstract

Provided are a positive electrode material, a method for preparing the positive electrode material, a positive electrode sheet, a battery, and an electric device. The positive electrode material comprises a core and a shell covering the core, the core and the shell both comprise primary particles, most of the primary particles in the core are distributed in the radial direction of the core, and the distribution of most of the primary particles in the shell is different from the radial distribution in the core. The particle strength of the positive electrode material is improved, thereby improving the cycle life, high-temperature storage performance and energy density of the battery.
