  • Template-based methods of making and using ceramic solids
    Patent number: 10388975
    Abstract: Various embodiments relate to a method comprising forming a template from a template precursor, wherein the template contains an entrapped ceramic precursor, which can be further processed to form a ceramic solid, such as an oxide ceramic solid. In one embodiment, the template precursor is a hydrogel precursor and the template is a hydrogel template. The hydrogel template can include, for example, agarose, chitosan, alginate or a photo-initiating receptive hydrogel template such as a functionalized poly(ethylene glycol). Various devices, including electrolyte interfaces and energy storage devices, as well as thermoelectric devices are also provided. In one embodiment, the oxide ceramic solid is a cubic garnet having a nominal formula of Li7La3Zr2O12 (LLZO).

  • Methods of making and using oxide ceramic solids and products and devices related thereto
    Patent number: 9093717
    Abstract: Various embodiments relate to a method comprising combining a chelating agent, one or more non-aqueous organic solvents and one or more metallic compounds to produce an oxide ceramic solid in a non-aqueous solution based reaction, wherein the oxide ceramic solid contains metal-oxygen-metal bonds. The oxide ceramic solid can comprise, for example, a gel or a powder. Various devices, including electrolyte interfaces and energy storage devices, are also provided. In one embodiment, the oxide ceramic solid is a cubic garnet having a nominal formula of Li7La3Zr2O12 (LLZO).
