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.

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 on one negative electrode and said electrolyte, said enclosure including a gas permeable membrane allowing passage of cell gases into and out of said cell but preventing passage of said electrolyte out of said cell, said membrane comprising at least one corrugated layer of a membrane material.
