Presented are electrochemical devices with in-stack reference electrodes, methods for making/using such devices, and battery cells with stacked electrodes segregated by electrode separator assemblies having built-in reference electrodes. An electrochemical device includes a protective outer housing that contains an ion-conducting electrolyte. A stack of working electrodes is packaged inside the device housing in electrochemical contact with the electrolyte. At least one electrode separator assembly is located inside the housing, interposed between a neighboring pair of these working electrodes. The electrode separator assembly includes an electrically insulating separator sheet with a reference electrode. A tab pocket, which projects from an end of the separator sheet, includes a tab chamber with a chamber opening. An electrode tab is formed with an electrically conductive material and attached to the tab pocket. One end of the electrode tab is disposed in the tab chamber and the other end projects out from the chamber opening.
