| titleOfInvention | A kind of organosulfur molecule based on nickel-mercaptobenzimidazole coordination compound and its preparation method and application |
| abstract | The invention discloses a polysulfide nickel-mercaptobenzimidazole complex compound and a preparation method and application thereof. The preparation method comprises the following steps: (1) respectively dissolving nickel salt and 2-mercaptobenzimidazole in a solvent, The obtained solution is mixed with an amino weak alkaline solvent, and reacted at a certain temperature to obtain a nickel-mercaptobenzimidazole coordination compound; (2) the nickel-mercaptobenzimidazole coordination compound obtained in step (1) is mixed with sulfur powder Evenly, the reaction is heated in an inert gas atmosphere, and after the reaction is completed, the product is separated to obtain a nickel polysulfide-mercaptobenzimidazole complex. The lithium-sulfur battery prepared by using the nickel polysulfide-mercaptobenzimidazole coordination compound as the positive electrode material has good cycle stability, high-rate charge-discharge performance and high-sulfur loading performance, and the first-cycle capacity is 1354.9mAh at 0.2C g ‑1 , a capacity of 1179.5 mAh g ‑1 remains after 100 cycles, and the Coulombic efficiency during cycling is close to 100%. |
