Abstract
An electrical energy store is provided, including a storage cell, which in turn has an air electrode, which is connected to air channels in an air supply device, and a storage electrode, wherein the storage electrode adjoins a storage structure, wherein electrical contacts rest on the storage electrode, further wherein contact pins which protrude out of a surface of the storage structure are integrated in the storage structure, and the contact pins are in electrical contact with the storage electrode.
Claims19
An electrical energy store comprising:
- a storage cell, which in turn comprises an air electrode, which is connected to air channels of an air inlet apparatus, and
- a storage electrode, wherein the storage electrode adjoins a storage structure comprising a porous energy storage medium comprising a functionally effective oxidizable material as an active storage material, wherein electrical contacts rest on the storage electrode,
- wherein contact pins are integrated in the storage structure, said contact pins protruding out of a surface of the storage structure and being in electrical contact with the storage electrode, and
- wherein the functionally effective oxidizable material comprises at least one of iron and iron oxide.
An electrical energy store comprising:
- an electrode/electrolyte unit comprising an air electrode, a solid electrolyte and a storage electrode;
- a storage structure comprising an active storage material;
- a plurality of contact pins extending through a thickness of the storage material, a first end of the contact pins extending beyond the thickness of the storage material to make contact with the storage electrode;
- an interconnector plate comprising an upper side in contact with a second end of the contact pins extending beyond the thickness of the storage material;
- and
- contact webs formed on a lower side of the interconnector plate and defining air channels there between.
An electrical energy store comprising:
- an electrode/electrolyte unit comprising an air electrode, a solid electrolyte and a storage electrode;
- an interconnector plate comprising contact webs defining air channels in contact with the air electrode;
- a storage structure comprising an active storage material;
- and
- a plurality of contact pins extending through a thickness of the storage structure, an end of each contact pin extending beyond the thickness of the storage structure to make contact with the storage electrode.
