Abstract
A preparation method of a positive electrode material of a lithium battery is provided, including mixing a compound containing at least one ethylenically-unsaturated group and one carbonyl group or a derivative thereof and a Ni-rich oxide of lithium and transition metal to react. The compound containing at least one ethylenically-unsaturated group and one carbonyl group is selected from a group consisting of a maleimide-based compound, an acrylate-based compound, a methacrylate-based compound, an acrylamide-based compound, a vinylamide-based compound, and a combination thereof, and the Ni-rich oxide of lithium and transition metal is represented by formula I,LiNiMO Formula I wherein x+y=1, 1>x≥0.5, and M is at least one transition metal element except Ni.
