Rechargeable bipolar aluminum-ion battery and associated uses

A rechargeable bipolar aluminum-ion battery comprising:

• a plurality of electrochemical cells stacked in series, each of which in turn comprises:
• a first electrode, comprising an aluminum sheet that undergoes an oxidation reaction during battery discharging, and a reduction reaction during battery charging;
• a second electrode, comprising a carbonaceous material that undergoes a reduction reaction during battery discharging and an oxidation reaction during battery charging;
• and,
• a separation membrane, arranged as a mechanical spacer between the first and the second electrode but allowing ionic exchange between said electrodes;
• an electrolyte, in which the plurality of electrochemical cells are submerged and which transports the ions released in the first electrode and in the second electrode during the charge and discharge cycles of the battery;
• a first current collector, comprising a graphite sheet arranged in contact with the first electrode of a cell arranged at a first end of the series of electrochemical cells;
• a second current collector, comprising a graphite sheet arranged in contact with the second electrode of a cell arranged at a second end of the series of electrochemical cells;
• and,
• a housing that houses the plurality of electrochemical cells, the electrolyte, the first current collector and the second current collector,
• said battery being characterised in that, in the plurality of stacked electrochemical cells, the consecutive cells are connected by a graphite sheet arranged between said consecutive cells.
