Abstract
A rechargeable multi-cell battery including a plurality of electrochemical cells. Each of the cells includes a gas port that allows passage of cell gases into and out of the cell but prevent passage of cell electrolyte out of the cell. The gas port may be a gas permeable membrane. The multi-cell batter may be a bipolar battery.
Claims69
A multi-cell battery, comprising:
- a battery case;
- and
- a plurality of electrochemical cells housed in said battery case, each of said cells including:
- at least one positive electrode, at least one negative electrode and an electrolyte;
- and
- an enclosure housing said at least one positive electrode, said at least one negative electrode and said electrolyte, said enclosure including a gas port allowing passage of cell gases into and out of said cell but preventing passage of said electrolyte out of said cell.
