The invention provides a method for preparing basic manganese oxide nanosheet self-assembled three-dimensional spheres through rapid precipitation. The method is particularly important in future industrial large-scale application and production. The method has various excellent characteristics of high efficiency, quickness, simplicity and the like in material preparation; the huge challenge of regulating and controlling the nano material that is the three-dimensional nanosheet self-assembled spheres caused by the rapid crystallization of the precipitation reaction is overcome; and the three-dimensional nanosheet self-assembled sphere nano material is prepared by the method. MnCO3 has low solubility and can slowly release Mn<2+> ions in hydrolysis equilibrium, so that the material can directionally grow in the direction of the three-dimensional nanosheet self-assembled spheres in the growth process. The invention provides the morphology and phase regulation and control method of basic manganese oxide nanosheet
