Abstract
A positive electrode material, a preparation method therefor, and an application thereof are disclosed. The cathode material is composed of secondary particles agglomerated by primary particles; wherein individual secondary particle contains an inner core structure, a middle layer, and a shell layer, in this order, along a direction from a center to a surface of the secondary particle; wherein the middle layer is distributed in a circular ring shape; and wherein the secondary particle has a structure of close packing of an inner core structure, loose and porous middle layer, and close packing of the shell layer.
