| titleOfInvention | Hollow carbon fiber negative electrode material for lithium ion battery and preparation method and application thereof |
| abstract | The invention discloses a hollow carbon fiber negative electrode material for a lithium ion battery, and a preparation method and application thereof. The preparation method comprises (1) immersing the biomass raw material in nitric acid solution for delignification treatment at 60-90 ℃ to obtain suspension; (2) and (3) carrying out ultrasonic dispersion on the obtained suspension, filtering and drying to obtain primary wood fibers, and then heating to 700-1100 ℃ under the protection of inert gas for pyrolysis and carbonization to obtain the carbon fiber cathode material. The cathode material of the invention well keeps the hollow fibrous morphology and has the characteristics of large specific capacity and excellent rate capability. The preparation method disclosed by the invention has the advantages of abundant raw material sources, environmental friendliness and reproducibility, and can be widely applied to the field of lithium ion battery preparation. |
