| titleOfInvention | Lithium-sulfur battery cathode material, preparation method and lithium-sulfur battery |
| abstract | Provide a sulfur-containing positive electrode material, comprising polar functional groups, the polar functional groups include one or more of -COOH, -OH, -C-O-C-, -NH 2 ; the polar functional group content It accounts for 3%-10% of the mass of the positive electrode material. Also provided are a preparation method of the positive electrode material and a lithium-sulfur battery comprising the positive electrode material. The present invention provides a positive electrode material rich in polar functional groups (including -COOH, -OH, -C-O-C-, -NH 2 ), which can anchor polysulfide ions on the positive electrode material and solve the problem of polysulfide The shuttle problem of things. At the same time, the content of polar functional groups in the positive electrode material is 3%-10%, and chemical adsorption is dominant in the adsorption of polysulfides at this content, which leads to the spontaneous endothermic adsorption process of polysulfides at this time. The adsorption process absorbs a large amount of battery heat and improves the thermal safety of the battery. |
