Terminal connection apparatus for battery cells having foil terminals
First Claim
1. A pressure connection apparatus for electrically connecting a metal foil anode terminal of a first battery cell to a metal foil cathode terminal of a second battery cell, the apparatus comprising:
- a conductive spring member having first and second end portions;
a first retaining member having a first pocket in which the foil anode terminal and the first end portion of the conductive spring member are received, the foil anode terminal being sandwiched between the first end portion of the conductive spring member and an interior periphery of said first pocket; and
a second retaining member having a second pocket in which the foil cathode terminal and the second end portion of the conductive spring member are received, the foil cathode terminal being sandwiched the second end portion of the conductive spring member and an interior periphery of said second pocket.

Abstract
A pressure connection apparatus includes a conductive spring member having first and second end portions that are curved, and first and second retaining members having curved pockets that are oppositely oriented for receiving the first and second curved ends of the conductive spring member. An aluminum foil terminal of one battery is sandwiched between the conductive spring and the pocket of the first retaining member, while a copper foil terminal of another battery is sandwiched between the conductive spring and the pocket of the second retaining member. The spring member is clad with aluminum on one side and copper on the other, and the end portions are oppositely curved so that the aluminum-clad side contacts the aluminum foil terminal within the pocket of the first retaining member, and the copper-clad side contacts the copper foil terminal within the pocket of the second retaining member.
