Electrochemical cell with three-dimensional electrode structure

An electrochemical cell, comprising:

• a casing that:
• comprises a lower first element in the form of a vessel, an internal surface of which is at least partially covered by a layer of conductive material so as to form a current collector of a first electrode with a first polarity;
• comprises an upper second element in the form of a cover for closing the vessel;
• houses a three-dimensional electrode structure with a first electric polarity;
• houses a three-dimensional electrode structure with a second electric polarity opposite to the first electric polarity;
• and
• contains an electrolyte as an ionic conductive medium,
• wherein the three-dimensional electrode structure with the second electric polarity comprises a series of electrodes with a second polarity, each of the electrodes with the second polarity is a vertical bar, which comprises a central core made of conductive material that is covered with a solid layer of electrolyte and of active electrode material with the second polarity,
• wherein an upper end section of each of the central cores made of conductive material vertically extends through the cover for closing the vessel, and all the upper end sections of the central cores made of conductive material are electrically connected together by a collector plate arranged above the cover.
