Abstract
The present disclosure relates to a method for forming solid-state electrolytes, electrodes, current collectors, and/or conductive additives used in solid-state batteries. In one version, the method includes depositing a stabilization coating on a powdered electrolyte material, or a powdered electrode material, or a powdered conductive additive material and forming a slurry comprising the coated material. The slurry is then cast on a surface to form a layer, and the layer is sintered to form a solid state electrolyte, or an electrode, or an electrode having the conductive additive.
Claims19
A method for forming a lithium ion conducting solid-state electrolyte, the method comprising:
- (a) depositing a stabilization coating on a powdered electrolyte material;
- (b) forming a slurry comprising the coated electrolyte material;
- (c) casting the slurry on a surface to form a layer;
- and
- (d) sintering the layer to form the solid-state electrolyte,
- wherein the stabilization coating is applied as an oxide precursor that decomposes to one or more oxides upon thermal treatment.
