  • Publication number: 20210257658
    Abstract: Disclosed is a method of fabricating a battery or battery component having a solid state electrolyte. A scaffold is provided, the scaffold comprising: a dense central layer comprising a dense electrolyte material, the dense central layer having a first surface, and a second surface opposite the first surface; a first porous layer comprising a first porous electrolyte material, the first porous layer disposed on the first surface of the dense central layer, the porous electrolyte material having a first network of pores therein; wherein each of the dense electrolyte material and the first porous electrolyte material are independently selected from garnet materials. Carbon is infiltrated into the first porous layer. Sulfur is also infiltrated into the first porous layer. The battery component may be used in a variety of battery configurations.

  • Patent number: 10276892
    Abstract: Solid electrolytes compositions, methods of making the solid electrolytes, and methods of using the solid electrolytes in batteries and other electrochemical technologies are disclosed. The method of producing a solid electrolyte comprises (a) ball milling Na2CO3, SiO2, NH4H2PO4, a zirconium source, and a dopant to produce a ball milled powder; (b) calcining the ball milled powder to produce a calcined powder; and (c) sintering the calcined powder to produce a solid electrolyte. The zirconium source for the solid electrolyte may be ZrO2. The dopant for the solid electrolyte may be AI2O3, Fe2O3, Sb2O3, Yb2O3, or Dy2O3.

  • Publication number: 20170155169
    Abstract: Ceramic ion-conducing structures are disclosed. The structures can be in the form of a single layer or multilayer structures. A ceramic ion-conducting structure can be a layer. In an example, the ceramic ion-conducing material does not have observable dendrites (e.g., lithium dendrites). Methods of fabricating ceramic-ionic conducing structures are also disclosed. The methods are based on particular slurry formulation methods and/or particular sintering methods. The methods can be tape casting methods. Uses of ceramic ion-conducing structures are disclosed. For example, the ceramic ion conducing structures can be used as solid-state electrolyte materials in ion-conducing batteries (e.g., solid-state ion-conducing batteries). An ion-conducting battery can comprise ion-conducting solid state electrolyte comprising one or more ceramic ion conducing material of the present disclosure.
