Lithium-ion battery negative electrode material bitumen-based porous carbon/ZnMn2O4 preparation method

The invention relates to a lithium-ion battery negative electrode material bitumen-based porous carbon/ZnMn2O4 preparation method, and belongs to the category of the new material preparation technology and belongs to the technical field of carbon material and electrochemistry crossing. The preparation method is characterized in that a large amount of inexpensive petroleum bitumen is adopted as a carbon source and nanometer zinc oxide is adopted as a template to prepare bitumen-based porous carbon, washing and drying are performed, then zinc nitrate hexahydrate and manganese nitrate are added, and low-temperature drying and calcination under inert gas protection are sequentially performed so as to obtain the lithium-ion battery bitumen-based porous carbon/ZnMn2O4 negative electrode material, wherein the product has characteristics of high discharge specific capacity and good cycle performance, and is the lithium-ion secondary battery negative electrode material with the good application prospect.
