| titleOfInvention | Lithium-sulfur battery electrolyte, preparation method thereof, and lithium-sulfur battery |
| abstract | The application discloses a lithium-sulfur battery electrolyte, a preparation method thereof, and a lithium-sulfur battery. The lithium-sulfur battery electrolyte of the present application includes an organic solvent, a lithium salt and an additive, and the organic solvent includes a dissolution layer solvent and an encapsulation layer solvent, wherein the volume of the encapsulation layer solvent accounts for 10% to 40% of the total volume of the organic solvent; The solvent for the dissolving layer includes one or more of ether compounds, amide compounds, sulfone compounds and nitrile compounds for dissolving the polysulfides generated on the positive side of the lithium-sulfur battery; the solvent for the encapsulation layer includes A fluorinated ether for reducing the solubility of polysulfides in the electrolyte of the lithium-sulfur battery. In the present application, by adding the solvent for the dissolution layer and the solvent for the encapsulation layer, the lithium-sulfur battery electrolyte can meet the needs of promoting the conversion kinetics of the positive electrode and protecting the negative electrode at the same time, thereby improving the cycle life and Coulomb efficiency of the lithium-sulfur battery. |
