The invention discloses a nano flower-like MOS 2 / acid modified pitch coke activated carbon sodium ion battery negative electrode material and a preparation method, and belongs to the technical field of sodium ion battery negative electrode material preparation. After modification, acid-modified activated carbon was obtained, and then acid-modified activated carbon was used as conductive substrate, ammonium molybdate tetrahydrate as molybdenum source, thiourea as sulfur source and reducing agent, and ammonium molybdate tetrahydrate and thiourea were added to deionized water. Stir evenly with acid-modified activated carbon, and finally transfer it to a hydrothermal kettle for hydrothermal treatment to obtain nano-flower-like MOS 2 / acid-modified pitch coke activated carbon sodium-ion battery anode material. The preparation method is simple to operate, low in cost, and High yield and good reproducibility. The MOS 2 / FAC sodium ion battery anode material prepared by the method of the invention has excellent cycle stability. |
