Embodiments described herein relate generally to electrochemical cells including a selectively permeable membrane and systems and methods for manufacturing the same. In some embodiments, the selectively permeable membrane can include a solid-state electrolyte material. In some embodiments, electrochemical cells can include a cathode disposed on a cathode current collector, an anode disposed on an anode current collector, and the selectively permeable membrane disposed therebetween. In some embodiments, the cathode and/or anode can include a slurry of an active material and a conductive material in a liquid electrolyte. In some embodiments, a catholyte can be different from an anolyte. In some embodiments, the catholyte can be optimized to improve the redox electrochemistry of the cathode and the anolyte can be optimized to improve the redox electrochemistry of the anode. In some embodiments, the selectively permeable membrane can be configured to isolate the catholyte from the anolyte. 1. An electrochemical cell , comprising:an anode including anode current collector, anode material, and an anolyte;a cathode including cathode current collector, cathode material, and an catholyte; anda selectively permeable membrane disposed between the anode and the cathode, the selectively permeable membrane configured to chemically and/or fluidically isolate the anode from the cathode.2. The electrochemical cell of claim 1 , wherein the selectively permeable membrane includes solid-state electrolyte material selected from at least one of a garnet structure claim 1 , a perovskite structure claim 1 , a phosphate-based Lithium Super Ionic Conductor (LISICON) structure claim 1 , LaLiTiO claim 1 , LiAlTi(PO) claim 1 , LiLaZrO claim 1 , Li6LaZrTaO(LIZO) 50LiSiO.50LBO claim 1 , LiPON(lithium phosphorousoxynitride claim 1 , LiPON) claim 1 , LiSiPO claim 1 , LiBN claim 1 , LiBO—LiSO claim 1 , LiBO—LiSO—LiCO(LIBSCO claim 1 , pseudoternary system) claim 1 , and/or sulfide contained solid ...
