| titleOfInvention | Preparation method of composite fiber anode material of lithium-sulfur battery |
| abstract | The invention relates to a preparation method of a composite fiber anode material of a lithium-sulfur battery. The preparation method comprises the following steps of: using glass fiber as a precursor, and corroding glass fiber after the surface of the fiber is plated with nickel by using a chemical plating method, so as to prepare a micron-level hollow nickel fiber tube; secondly, growing dense noanometer carbon fiber on the inner surface and the outer surface of the end part of the nickel fiber tube by using a microwave plasma chemistry vapor deposition method; diffusing a mixture of uniformly mixing sulfur and powder carbon with a binder according to a certain ratio in an organic solvent, and stirring to obtain slurry; uniformly coating the slurry on a current collector thin sheet; and preparing an anode after being dried. According to the preparation method provided by the invention, the micron-level hollow nickel fiber tube is used as a main branch and a nanometer-level carbon fiber as a secondary branch, so as to form a space network structure; and the carbon fiber and a conductive agent have a large contact area, so as to form a good conductive channel. The preparation method is beneficial to the improvement on the battery circulation property. |
