Abstract

A device of the present invention is used for forming a layered battery cell having at least first electrode and at least one second electrode of charge opposite from said first electrode and a separator layer positioned between the first and second electrodes and at least one of a first current collector connected to at least one of the first and second electrodes and at least one of a second current collector connected to at least one of the first and second electrodes. At least one support member is integrated with an assembly line. A plurality of pins extend from the support member for receiving the first and second electrodes and the first and second current collectors layered with one another to assemble the same into a unitary package.

Claims

1. A cell having at least first electrode and at least one second electrode of charge opposite from said first electrode and a separator layer positioned between the first and second electrodes;

said lithium cell comprising;

a shell having an upper wall and a lower wall defining extending over the first and second insulators thereby encapsulating the first and second electrodes;

a first insulator and a second insulator extending over the first electrode and the second insulator extending over the second electrode; and

a conductor device disposed between said first and second insulators and extending through each of said upper wall and said lower wall to define a boss around and above each of said first insulator and said second insulator.

2. A cell for a battery pack as set forth in claim 1 wherein said conductor device is further defined by at least one tube each having terminal ends and a radial lip integral with and extending outwardly from said tube.
