Abstract
A rechargeable electrical storage device is disclosed, where one embodiment utilizes an anion (“A”) conducting electrolyte (18) and ion transfer between two electrodes (17, 19) where one electrode is preferably a metal electrode 19 that contains a mixture of metal and metal oxide, so that during operation, oxide-ions shuttle between the two electrodes (17, 19) in charging and discharging modes and the metal electrode (19) serves as a reservoir of species relevant to anion “A”.
Claims20
An electrical storage device comprising anion conducting electrolyte and two electrodes, where there is ion transfer between electrodes on either side of the electrolyte, where one electrode is a reservoir for ions and where ions can be transferred back and forth between electrodes.
A battery cell using a metallic electrode in combination with oxide-ion electrolyte conductors and an air electrode, the cell capable of operating in a charging and discharging mode, to store electrical energy in the metallic electrode, where, the discharging mode is:
- yMe+x/2 O2=MeyOx
- the charging mode is:
- MeyOx=x/2 O2+yMe, and where x/y=0.5 to 3.0 and Me=metal.
A bank of cells comprising a plurality of electrically connected solid or hollow elongated tubular cells, each cell capable of operating in a charging and discharging mode, each cell comprising a single phase or two-phase metallic material which can be oxidized for use as a first electrode, having a melting point over 400° C., and, a second electrode material which can transfer air to an electrolyte, and an electrolyte therebetween that can transfer oxide ions, where the metallic electrode is a reservoir of oxygen, where the discharging mode is:
- yMe+x/2 O2=MeyOx,
- the charging mode is:
- MeyOx=x/2 O2+yMe, where x/y=0.5 to 3.0, Me=metal, and where the bank of cells store electrical energy, and have a source of air to contact the second electrode material.
