Original Abstract Submitted
A positive active material, including a matrix and a first material existing on a surface of the matrix. The matrix includes a core and a shell layer. An interplanar spacing d1 of a (003) plane of the first material is less than an interplanar spacing d2 of a (003) plane of the core. By controlling the interplanar spacing d1 of the (003) plane of the first material to be less than the interplanar spacing d2 of the (003) plane of the core, the structural stability of the surface of the positive active material can be improved, and an interfacial charge transfer resistance of the positive active material can be reduced, thereby helping to improve both cycle performance and kinetic performance of the electrochemical device.
