An ROB stack (') contains a plurality of stacked ROB cells () made from: thin metal bipolar housings () having air inlets and exits and horizontal channels for feeding air between the inlets () and exits (), the channel having top ridges and also grooves () for containing active material (); a porous air electrode () next to the air channels allowing air contact; a metal electrode (); and an oxygen ion transfer membrane () acting as electrolyte; wherein the plurality of all the assemblies form vertical air inlet and outlet plenums.

A rechargeable oxide-ion battery cell, operating below 800&#xb0; C., containing a molten salt-containing electrode, made of active metal-active metal oxide-active metal salt; which electrode is associated with an electrolyteand an air electrodeto provide the cell

Molten salt-containing metal electrode for rechargeable oxide-ion battery cells operating below 800&#xb0;C

An all solid state rechargeable oxide-ion (ROB) battery () has a thermal energy storage (TES) unit () between two oxide-ion cells () with metal-metal oxide electrodes () on opposite sides of an anion conducting solid electrolyte () where none of the electrodes is contact with air.

All solid state rechargeable oxide-ion battery (ROB) system

The outer surface of a metal electrodeof a rechargeable oxide-ion battery (ROB) cell is covered by its own dense electrolyteand interconnection, where the dense electrolyteand interconnectionhermetically seal the metal electrode away from oxygen-containing environment to prevent direct contact between active metal and oxygen which would lead to self discharge, thus, producing a self-sealed metal electrode of a ROB cell without introducing additional sealing components.
