Abstract
The present disclosure describes a method of providing residual compressive stress to a lithium-based solid electrolyte by ion exchanging lithium ions with ions having a larger ionic radius that the lithium ions.
Claims22
A method of providing residual compressive stress to a lithium-based solid electrolyte comprising
- subjecting the lithium-based solid electrolyte to ion exchange conditions where lithium ions within the lithium-based solid electrolyte are exchanged with ions in a sub surface region of the lithium-based solid electrolyte so as to impart residual compressive stresses in the sub-surface region of the lithium-based solid electrolyte,
- wherein the ions have a larger ionic radius than the lithium ions.
A lithium-based solid electrolyte comprising diffused potassium ions or diffused silver ions.
