Abstract
A bicontinuous separating layer includes a separating matrix having pores and a solid-state electrolyte disposed in the pores of the separating matrix. In certain variations, the bicontinuous separating layer is prepared by contacting a solid-state electrolyte liquid-state precursor with the separating matrix and heating the infiltrated separating matrix to a temperature between about 25° C. and about 300° C. The solid-state electrolyte liquid-state precursor includes a solvent and a solid-state electrolyte powder or a solid-state electrolyte precursor. In other variations, the bicontinuous separating layer may be prepared by contacting a solid-state electrolyte powder with a separating matrix to form a physical mixture and heating the physical mixture to a temperature between about 240° C. and about 500° C., where the separating matrix is defined by a polymer having a melting temperature greater than about 215° C., and the solid-state electrolyte has a melting temperature greater than about 300° C.
