  • Patent number: 10270090
    Abstract: A production method for a cathode material of a lithium sulfur battery includes, in sequence: a step of preparing a first dispersed solution in which a carbon particle is dispersed in a lithium sulfate solution; a step of adding a solvent in the first dispersed solution, the solvent being a solvent in which lithium sulfate is insoluble; a step of separating a precursor particle from the first dispersed solution in which the solvent is added; and a step of changing the precursor particle into a cathode active material particle by heating the precursor particle under an inert atmosphere.

  • Patent number: 9231223
    Abstract: The present invention provides of a three-dimensional bicontinuous heterostructure, a method of producing same, and the application of this structure towards the realization of photodetecting and photovoltaic devices working in the visible and the near-infrared. The three-dimensional bicontinuous heterostructure includes two interpenetrating layers which are spatially continuous, they are include only protrusions or peninsulas, and no islands. The method of producing the three-dimensional biocontinuous heterostructure relies on forming an essentially planar continuous bottom layer of a first material; forming a layer of this first material on top of the bottom layer which is textured to produce protrusions for subsequent interpenetration with a second material, coating this second material onto this structure; and forming a final coating with the second material that ensures that only the second material is contacted by subsequent layer.
