Abstract:
1. An improved electrode assembly for use inside a battery having case with electrolyte therein, comprising: a plurality of electrodes arranged in a stacked relationship; said plurality of electrodes including at least two positive electrodes, each said positive electrode having a positive active surface area communicating with a positive conducting edge portion; said plurality of electrodes including at least two negative electrodes, each said negative electrode having a negative active surface area communicating with a negative conducting edge portion; each said positive conducting edge portion forming a positive current collector along substantially one entire edge of said positive electrodes; each said negative conducting edge portion forming a negative current collector along substantially one entire edge of each of said negative electrodes; said positive current collectors, of each of said positive electrodes, stacked adjacent to each other and in substantial contact with each other along their respective entire lengths, thereby forming a positive edge portion; said negative current collectors, of each of said negative electrodes stacked adjacent to each other and in substantial contact with each other along their respective entire lengths, thereby forming a negative edge portion; a porous separator disposed between said positive active surface area of each of said positive electrodes and said negative active surface area of each of said negative electrodes; a first elongated conductor in contact with substantially the entire length of said positive edge portion; means for attachment of said first elongated conductor to said positive edge portion; a second elongated conductor in contact with substantially the entire length of said negative edge portion; means for attachment of said second elongated conductor to said negative edge portion; and said first elongated conductor and said second elongated conductor adapted at their respective distal ends, exterior to said battery, for communication of electrical power to an electrical device.
