| titleOfInvention | Biomass carbon fiber negative electrode material for lithium ion battery and preparation method and application thereof |
| abstract | The invention discloses a biomass carbon fiber negative electrode material for a lithium ion battery, and a preparation method and application thereof, wherein the biomass carbon fiber negative electrode material for the lithium ion battery is fibrous in microscopic appearance, and the diameter of biomass carbon fiber is 1-5 mu m. The preparation method comprises (1) immersing the biomass raw material in an alkali solution for hydrothermal pretreatment at 120-180 ℃ to obtain a suspension; (2) and filtering the obtained suspension to obtain a precursor, performing ultrasonic dispersion on the precursor, filtering and drying, and heating to 700-1100 ℃ under the protection of inert gas for pyrolysis and carbonization to obtain the cathode material. The negative electrode material disclosed by the invention well keeps fibrous morphology, has the advantages of high first coulombic efficiency, large specific capacity, rich raw material sources of the preparation method, environmental friendliness, reproducibility and simple process, and can be widely applied to the field of lithium ion battery preparation. |
