  • Patent number: 10347917
    Abstract: A method for manufacturing a positive active material for an all-solid Lithium-Sulfur battery includes preparing a lithium sulfide solution by dissolving lithium sulfide in anhydrous ethanol. A mixture is prepared by mixing a carbon fiber to the lithium sulfide solution. A lithium sulfide-carbon fiber composite is prepared by drying the mixture of the carbon fiber and the lithium sulfide solution to deposit the lithium sulfide on a surface of the carbon fiber. The lithium sulfide-carbon fiber composite is heated at 400 to 600° C.

  • Publication number: 20180053932
    Abstract: A cathode slurry composition of an all-solid-state ion battery and a cathode of an all-solid-state ion battery comprising the same are provided herein. More particularly, the cathode slurry composition—and the cathode comprising the cathode slurry composition thereof comprises a binder that can be completely dissolved in the cathode slurry by using hydroxylated nitrile butadiene rubber having a nitrile content of about 20 wt % to about 3 wt % as a binder and a mixture of three components having different polarities as a dispersing solvent. As a result, dispersion and cohesion of these components are largely improved in the slurry.
