摘要： An electrochemical cell includes a casing that: includes a lower first element in the form of a vessel, the internal surface of which is at least partially covered by a layer of conductive material so as to form the current collector of the first electrode with a first polarity; includes 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. The three-dimensional electrode structure with the second electric polarity includes a series of electrodes with a second polarity, each of which is an elongated body with a vertical orientation.

摘要： A device manufactures an electrode strip for a battery including a current collector strip and at least one layer of electrochemically active composite material on either side of the current collector strip. The device includes an extruder including a sheath, an extrusion head, and an extrusion screw. The extrusion screw includes an outer tube and an inner tube that are coaxial and fitted into one another. The outer tube is mounted so as to be rotatably movable relative to the sheath. The inner tube is stationary relative to the sheath and includes an outlet located upstream of the extrusion head. Moreover, the manufacturing device includes advancing and unwinding structure to convey the current collector strip through the inner tube and up to the extrusion head.
