The bipolar electrochemical battery of the invention comprises:
- a stack of at least two electrochemical cells electrically arranged
in series with the positive face of each cell contacting the negative face of an
adjacent cell, wherein each of the cells comprises
- (a) a negative electrode;
- (b) a positive electrode;
- (c) a separator between the electrodes, wherein the separator includes
an electrolyte;
- (d) a first electrically conductive lamination comprising a first inner
metal layer and a first polymeric outer layer, said first polymeric outer layer
having at least one perforation therein to expose the first inner metal layer,
said first electrically conductive lamination being in electrical contact with
the outer face of the negative electrode; and
- (e) a second electrically conductive lamination comprising a second
inner metal layer and a second polymeric outer layer, said second polymeric outer
layer having at least one perforation therein to expose the second inner metal
layer, said second electrically conductive lamination being in electrical contact
with the outer face of the positive electrode; wherein the first and second laminations
are sealed peripherally to each other to form an enclosure including the electrodes,
the separator and the electrolyte.
