Positive electrode material, preparation method thereof, and applications

Abstract

The disclosure proposes a positive electrode material, a preparation method thereof, and applications. The positive electrode material at least includes a positive electrode active material including LiNi0.5Mn1.5O4; and a coating layer coated on the positive electrode active material, wherein the coating layer includes a halide solid electrolyte, and the chemical formula of the halide solid electrolyte is Liz+aZr1-aFeaCl6-x-yBrxIy, in which 0<a≤0.5; x=0 to 6, y=0 to 6, x+y≤6. The disclosure proposes the positive electrode material, the preparation method thereof, and the applications, which can improve the rate performance and the cycle performance of a lithium-ion battery.
