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).
Claims7
A method of making an electrolyte interface comprising:
- providing a slurry formed using a chelating agent in a non-aqueous solution-based reaction performed at a temperature ranging from about −15 to about 50° C. and including an oxide ceramic compound having an atomic formula comprising:
- AxRyCzSaO12,
- wherein A is a first cationic species selected from H, Li, Na, Mg, Al and/or Ga and residing in an 8a, 16f, 32g, 24d, 48g or 96h site;
- R is a second cationic species selected from La, Ba and/or Ce and residing in a 24c site;
- and
- C is a third cationic species selected from Zr, Ta, Nb, Y or Hf and residing in the 16a site;
- providing an oxide ceramic electrolyte that includes a compound selected from AxRyCzSaO12;
- forming at least one 3D feature on the oxide ceramic electrolyte to provide an un-sintered electrolyte interface, wherein the 3D feature includes the slurry;
- and
- sintering the un-sintered electrolyte interface to provide the electrolyte interface.
