Abstract
A solid-state electrolyte for an electrochemical cell that cycles lithium ions is provided. The solid-state electrolyte includes a sintered layer that includes a plurality of lithiated zeolite particles having pores and a lithium-containing material disposed in at least a portion of the pores of the lithiated zeolite particles. For example, each lithiated zeolite particle has a porosity greater than or equal to about 20 vol. % to less than or equal to about 80 vol. %, and the lithium-containing material occupies greater than or equal to about 20% to less than or equal to about 80% of a total porosity of each lithiated zeolite particle. In certain instances, the sintered layer further includes a superionic additive that is also disposed in a portion of the pores of the lithiated zeolite particles, such that the sintered layer has an ionic conductivity between about 1×10S·cmand about 1×10S·cm.
