Abstract
Provided is a positive electrode material for a lithium battery with an atomic ratio expressed by the formula (I) Li(MMn)(OZ) for 0.8≤a≤1.2, 0≤x≤1 and 0≤y≤1 in which M is one or more of Li, Na, K, Ca, Mg, Al, Ti, Sc, Ge, V, Cr, Zr, Co, Ni, Zn, Cu, La, Ce, Mn, Hf, Nb, Ta, Mo, W, Ru, Ag, Sn, Pb and Si and Z is one or more of OH, halogens, N, P, S and O, and the primary particles of the positive electrode material have a spheroidal topography. The adjacent (111) family planes of the primary particles are connected by curved surfaces without obvious edges. A preparing method of a positive electrode material for a lithium battery and a lithium battery are also provided. The positive electrode material of the present invention provides a good high-temperature cycling performance and filling capability.
