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 including thermal barriers and built-in reference electrodes. An electrochemical device, such as a lithium-class secondary battery cell, includes an insulated and sealed housing with an ion-conducting electrolyte located inside the housing. A stack of working electrodes is also located inside the device housing, in electrochemical contact with the electrolyte. At least one electrode separator assembly is located inside the device housing, interposed between a neighboring pair of (anode and cathode) working electrodes. The electrode separator assembly includes a separator layer fabricated with an electrically insulating material that is sufficiently porous to transmit therethrough the ions of the electrolyte. An electrically conductive current collector (CC) layer, a thermally insulating thermal barrier (TB) layer, and an active electrode reference electrode (RE) layer are attached to the separator layer.
