Abstract: The present invention discloses a preparation method for a spherical Zn—Mn metal compound. The preparation method comprises the following steps: adding a metal ion solution to a weak acid carbon dot solution; and then, adding a sodium carbonate solution to the above solution at an oil bath while stirring to obtain a spherical Zn—Mn metal carbonate compound. The present invention proposes that using water-soluble or ethanol-soluble carbon dots as a carrier and polyvinylpyrrolidone as a surfactant to prepare the spherical Zn—Mn metal compound, a novel preparation method for the Zn—Mn metal compound is formed. The prepared material may be applied to a lithium ion battery and may further be applied to application researches in the field of synthesis of other electrochemical energy sources or photocatalytic materials.
