  • Patent number: 11961970
    Abstract: A lithium sulfur battery with a low solvating electrolyte at an amount of less than 2 ?l per mg sulfur. The electrolyte comprises dioxolane and hexylmethylether, as well as a Li salt, for example LiTSFi. The electrolyte is free from lithium nitrate, LiNO3.
    Type: Grant

  • Patent number: 11594760
    Abstract: The invention relates to an electrolyte, which is provided for an alkali-sulfur battery (e.g. for a Li—S battery). The electrolyte contains a non-polar, acyclic and non-fluorinated ether, a polar aprotic organic solvent, and a conducting salt for an alkali-sulfur battery. It has been found that, when such an electrolyte is used in an alkali-sulfur battery, a high-capacity, a low overvoltage, a high cycle stability, and a high Coulomb efficiency can be achieved in the alkali-sulfur battery and, in addition, as compared with an alkali-sulfur battery which contains a fluorinated ether in the electrolyte, a considerably improved gravimetric energy density is obtained. The invention further relates to a battery comprising the electrolyte according to the invention and to uses of the electrolyte according to the invention.
