Abstract

A bipolar battery includes a plurality of anodes and cathodes alternately stacked and isolated by separators with a through hole being formed at a center portion of each, and with a plurality of insertion holes being formed at peripheral portions of each, an anode connection member and cathode connection member inserted into the insertion holes of the anodes and cathodes, an anode insulation member formed at the bottom of the anode connection member, a cathode insulation member formed on the top of the cathode connection member, an anode contact member facilitating electrical connection of the anodes and an anode connection member, a cathode contact member facilitating electrical connection of the cathodes and a cathode connection member, an outer support member supporting the stacked anodes and cathodes, an electrolyte injection member inserted into the through holes of the anodes, cathodes, and separators for enabling injection of an electrolyte into the stacked anodes and cathodes, and a collector being shared by the cathode of an upper cell and the anode of an lower cell, for thereby easily increasing the current capacity.

Dependent claims

A bipolar battery, comprising:

a stackable cell including:
a plurality of anodes and cathodes alternately stacked and isolated by separators with a through hole being formed at a center portion of each of the anodes and cathodes, and with a plurality of insertion holes being formed at peripheral portions of the anodes and cathodes;
an anode connection means and a cathode connection means inserted into the insertion holes of the anodes and cathodes for selectively connecting the anodes and the cathodes;
a cathode insulation means formed on top of the cathode connection means and an anode insulation means formed at a bottom of the anode connection means;
an outer support means for supporting the stacked anodes and cathodes at an outer portions thereof;
an electrolyte injection means inserted into the through holes of the anodes, cathodes and separators for injecting an electrolyte into the stacked anode and cathode structure;
and
a collector supported by the outer support means and the electrolyte injection means and stacked on top of the anode positioned on the uppermost portion of the stacked anode and cathode structure and on top of the cathode insulation means and anode connection means,
whereby a predetermined number of said cells may be stacked.
