A hybrid separator for an electrochemical cell is provided, along with methods of making the hybrid separator. The hybrid separator includes a first metal-organic framework comprising copper and having a plurality of first pores and a second distinct metal-organic framework comprising indium or zinc and having a plurality of second pores. The hybrid separator is capable of adsorbing one or more lithium salts in at least one of the plurality of first pores or the plurality of second pores so as to be ionically conductive. The hybrid separator may have a conductivity greater than or equal to about 0.1 mS/cm to less than or equal to about 1 mS/cm and is substantially free of any polymeric binder.
A hybrid separator for an electrochemical cell that cycles lithium ions, the hybrid separator in a sheet form comprising a first metal-organic framework (MOF) comprising copper (Cu) and having a plurality of first pores and a second distinct metal-organic framework (MOF) comprising indium (In) or zinc (Zn) and having a plurality of second pores, wherein the hybrid separator is capable of adsorbing one or more lithium salts in at least one of the plurality of first pores or the plurality of second pores so as to be ionically conductive, wherein the hybrid separator is free of binder materials that are configured to provide mechanical stability, and wherein at least one of the first metal-organic framework (MOF) and the second metal-organic framework (MOF) maintains a cohesive shape in independent form.
