Preparation method and application of nano manganese metastannate material
The invention relates to the technical field of battery electrode materials, in particular to a preparation method and application of a nanometer manganese metastannate material. The preparation method comprises the following steps: dissolving manganese salt and tin salt in deionized water to obtain a precursor solution; under a stirring condition, adding an ammonia water mineralizer into the precursor solution until the pH value of the solution is 10-11 to obtain a mixed solution; carrying out hydrothermal reaction on the mixed solution, cooling to room temperature, and carrying out solid-liquid separation to obtain a product; and calcining the product in nitrogen to obtain the nano manganese metastannate material. The preparation method adopted by the invention is low in energy consumption, the obtained product is not easy to agglomerate, small in particle size and uniform in distribution, has a regular cubic morphology, and can be used for preparing the lithium ion negative electrode material, and the lithium ion negative electrode material prepared from the product has good cycle performance..
