Abstract: A manganese-based carbonate precursor of a positive electrode material for a secondary battery has a specific structure and composition and contains a trace amount of uniformly distributed Na element, a content of Na is in a range of 0.5-3 mol %, which range can ensure that the structural integrity and consistency of carbonate crystals are not affected. In addition, the trace amount of Na element is uniformly distributed inside the manganese-based carbonate precursor provided in the present application, and by means of simple mixing with a lithium source and sintering, a lithium-rich manganese-based material uniformly doped with Na element can be directly obtained without the need for introducing other Na source, whereby uneven doping of Na is effectively avoided, the doping effect is improved, and the electrical properties of the material are significantly improved.
