Abstract
In an embodiment, a softened solid-state electrolyte, comprises an oxide-based solid-state electrolyte, where at least a portion of the oxide anions in the oxide-based solid-state electrolyte is replaced with a replacement anion. In another embodiment, a softened solid-state electrolyte comprises a sulfide-based solid-state electrolyte, wherein at least a portion of the sulfide anions in the sulfide-based solid-state electrolyte is replaced with the replacement anion. When the replacement anion replaces the oxide anion, the replacement anion has a larger atomic radius than the oxide anion and when the replacement anion replaces the sulfide anion, the replacement anion has a larger atomic radius than the sulfide anion.
