  • Patent number: 11990607
    Abstract: A hybrid cathode for a Li—S battery may include an intercalation-type material and a conversion-type material. The conversion-type material, such as sulfur, may increase the gravimetric energy density, Eg, of the battery. The intercalation-type material may increase the electrical and ionic conductivity of the cathode and contribute to the capacity of the battery, enabling replacement of partial high-surface-area conductive carbon and increasing the volumetric energy density, Ev. In combination, the conversion-type material and the intercalation-type material may be used to increase Eg and Ev simultaneously while providing sufficient rate capability. In one example, a hybrid cathode includes an electrode and a cathode material. The cathode material includes a first concentration of an intercalation compound, a second concentration of sulfur, and a third concentration of carbon. Furthermore, the intercalation compound and sulfur contribute to the capacity of the Li—S battery within a voltage window of 1.
