An inorganic ion-conducting membrane treated to modify its surface properties can improve battery cell performance. Membrane surfaces positioned to directly interface with liquid electrolyte(s) on one or both of its major surfaces can be modified to mitigate polarization effects arising from ionic space charges at the solid electrolyte/liquid electrolyte interface when disposed in a battery cell. This surface modification can include fluid treatments that modify the ionic space charge layer to reduce battery cell polarization. The cell polarization can be reduced by at least 10 mV, 50 mV or at least 100 mV as a result of using this surface-modified membrane compared to the same membrane that was not surface-modified.
