Claim 14:
15. The method according to claim 14, wherein the step of providing the inner core material comprises the following steps:
step (1): mixing and stirring a manganese source, an element A source, and an acid in a container to obtain manganese salt particles doped with element A; and
step (2): mixing the manganese salt particles doped with element A with a lithium source, a phosphorus source, and an element R source in a solvent to obtain a slurry, and sintering the slurry under inert gas atmosphere protection to obtain lithium manganese phosphate doped with element A and element R, wherein the lithium manganese phosphate doped with element A and element R is Li1+xMn1−yAyP1−zRzO4, where x is −0.100 to 0.100, y is 0.001 to 0.500, z is 0.001 to 0.100, A is selected from one or more of Zn, Al, Na, K, Mg, Mo, W, Ti, V, Zr, Fe, Ni, Co, Ga, Sn, Sb, Nb, and Ge.
