| Zusammenfassung: | The invention relates to a lithium-sulfur battery cathode material and a preparation method thereof. The lithium-sulfur battery cathode material is prepared by mixing steady-state lithium powder and carbon. The battery prepared by the method shows relatively low impedance and is capable of effectively weakening shuttle effect and dendritic growth in a continuous charge-discharge process; compared with the conventional metal lithium foil, the battery shows better circulation property and rate capacity. |
