Abstract
Provided are solid-state electrolyte structures. The solid-state electrolyte structures are ion-conducting materials. The solid-state electrolyte structures may be formed by 3-D printing using 3-D printable compositions. 3-D printable compositions may include ion-conducting materials and at least one dispersant, a binder, a plasticizer, or a solvent or any combination of one or more dispersant, binder, plasticizer, or solvent. The solid-state electrolyte structures can be used in electrochemical devices.
Claims14
A solid-state electrolyte structure, comprising:
- a substrate of a first ion-conducting material and having a first surface, wherein the first ion-conducting material is a first solid-state ion-conducting electrolyte material;
- and
- a non-planar first ordered porous microstructure disposed on a first surface of the substrate, the first ordered porous microstructure comprising a second ion-conducting material, and the second ion-conducting material is a solid-state, ion-conducting electrolyte material;
- and
- wherein the first ordered porous microstructure comprises a plurality of columns arranged in a two-dimensional array.
