Abstract
A composite positive electrode material is Li[LiNiCoMnM]O, where x+a+b+c+d=1, 0<a, b, and c<1, 0≤d≤0.05, 0≤x, and the element M includes one or more of Al, B, Zr, Sr, Y, Sb, Ta, Na, K, W, Ti, Mg, Nb, Hf, Mo, and Ce. A span of the composite positive electrode material is 1.2-2.0. The composite positive electrode material includes first and second lithium-rich manganese-based positive electrode materials. The first lithium-rich manganese-based positive electrode material includes rod-like primary particles with a length of 0.1-1.5 μm and secondary particles with D50 of 3-8 μm. The second lithium-rich manganese-based positive electrode material includes spheroidal primary particles with a diameter of 0.1-400 nm and secondary particles with D50 of 8-20 μm.
