Abstract

A battery cell includes a first power tab and a first conducting wire. The first power tab may include a proximal end connected to the battery cell, and may provide a first output terminal for the battery cell. The first conducting wire may be connected to a distal end of the first power tab, and may be encircled by the first power tab. The first conducting wire may connect with a power circuit board to provide power from the battery cell.

First claim

What is claimed is:

1. A battery cell comprising:
a first power tab including a proximal end connected to the battery cell and a distal end, the first power tab to provide a first output terminal for the battery cell; and
a first conducting wire connected to the distal end of the first power tab, the first conducting wire encircled by the first power tab, the first conducting wire to connect with a power circuit board of an information handling system to provide power from the battery cell to the power circuit board.

2. The battery cell of claim 1 , further comprising:
a second power tab including a proximal end connected to the battery cell and a distal end, the second power tab to provide a second output terminal for the battery cell; and
a second conducting wire connected to the distal end of the second power tab, the second conducting wire encircled by the second power tab, the second conducting wire to connect with the power circuit board to provide power from the battery cell to the power circuit board.

3. The battery cell of claim 2 , wherein the first and second conducting wires are formed in response to a middle portion of a third wire being cut from the third wire prior to the battery cell being activated.

4. The battery cell of claim 1 , wherein the first conducting wire is connected to the distal end of the first power tab by being spot welded to the distal end.

5. The battery cell of claim 1 , wherein the first conducting wire is connected to a power interconnect of the power circuit board.

6. The battery cell of claim 1 , wherein the first conducting wire is connected to a via of the power circuit board.

7. The battery cell of claim 1 , wherein the first conducting wire enables a smaller amount of the power circuit board to be utilized to connect the battery cell to the power circuit board as compared to the first power tab.

8. The battery cell of claim 1 , wherein the first wire is encircled by the first power tab in response to the first wire being rolled along the first power tab.

9. A battery cell comprising:
a first power tab including a proximal end connected to the battery cell and a distal end, the first power tab to provide a first output terminal for the battery cell;
a first conducting wire connected to the distal end of the first power tab, the first conducting wire encircled by the first power tab, the first conducting wire to connect with a power circuit board of an information handling system to provide power from the battery cell to the power circuit board, wherein the first conducting wire is connected to the distal end of the first power tab by being spot welded to the distal end;
a second power tab including a proximal end connected to the battery cell and a distal end, the second power tab to provide a second output terminal for the battery cell; and
a second conducting wire connected to the distal end of the second power tab, the second conducting wire encircled by the second power tab, the second conducting wire to connect with the power circuit board to provide power from the battery cell to the power circuit board, wherein the first and second conducting wires are formed in response to a middle portion of a third wire being cut from the third wire prior to the battery cell being activated.

10. The battery cell of claim 9 , wherein the first conducting wire is connected to a power interconnect of the power circuit board.

11. The battery cell of claim 9 , wherein the first conducting wire is connected to a via of the power circuit board.

12. The battery cell of claim 9 , wherein the first conducting wire enables a smaller amount of the power circuit board to be utilized to connect the battery cell to the power circuit board as compared to the first power tab.

13. The battery cell of claim 9 , wherein the first wire is encircled by the first power tab in response to the first wire being rolled along the first power tab.
