Abstract
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.
