Abstract
The present application relates to the technical field of lithium batteries, and in particular to a preparation method for a positive electrode material, a positive electrode material, a positive electrode sheet, a battery, and an electric device. The method of the present application comprises: mixing a nitrate salt and a precursor in a solvent, and roasting to obtain a positive electrode material, wherein the precursor comprises LiFe<(1-y)>M<y>PO<4>, wherein M comprises one or more metal elements from Group IVB, Group VB, Group VIII, Group IIA, Group IIIA, Group IVA, and Group VA, and y is 0-0.1. The method of the present application improves the electronic conductivity of the positive electrode material, and the specific capacity and the cycle stability of the battery.
