Preparation process of anode material lithium manganate of spherical structure for lithium ion battery

The invention relates to the field of lithium ion battery materials, in particular to a preparation process of anode material lithium manganate (LiMn2O4) of a spherical structure for a lithium ion battery. Metal salt of manganese is used as a raw material and is dissolved into hot water to prepare solution of a certain concentration, the solution of the metal manganese and a precipitant simultaneously and concurrently flow into a reaction container according to a certain flow speed under a stirring condition; air is introduced to perform synthesis reaction; and spherical Mn3O4 precursor is obtained through aging and then is calcined with a lithium source to obtain the spherical anode material lithium manganate LiMn2O4 for the lithium ion battery. The preparation process of preparing the anode material lithium manganate LiMn2O4 of the lithium ion battery by taking the self-made spherical Mn3O4 as a precursor has the advantages of simple synthesis method, easiness in control over a process, high efficiency, low
