Abstract

A battery pack is provided for use in applications where lightweight and flexibility are desired, such as for powering an illuminated clothing article. A battery pack is provided consisting of a first and second fabrics, each having conductive traces applied upon its inside. The fabrics are sealed together forming a battery pouch area to hold and electrically connect a battery that is placed within it. Because the pack is made of fabric, and requires no connecting wires or hard case, excess weight and bulk is eliminated, resulting in a comfortable clothing article within a natural drape.

Claims

1. A flexible battery pack for holding and connecting a battery comprising:

a first fabric;

a first conductive trace upon said first fabric;

a second fabric;

a second conductive trace upon said second fabric; and

wherein the first fabric is attached to the second fabric such that said first and second conductive traces are configured to electrically connect to a said battery when placed between said first and second fabrics.

2. The battery pack of claim 1 wherein said first and second fabric comprises felt.

3. The battery pack of claim 1 wherein said first fabric is attached to said second fabric using sonic welding.

4. The battery pack of claim 1 wherein said first fabric has a perimeter and said first fabric is attached to said second fabric by sonically welding along said first fabric perimeter.

5. The battery pack of claim 1 wherein the second fabric comprises a slit for placing said battery between said first and second fabrics.

6. The battery pack of claim 1 wherein the first and second conductive traces comprise conductive protrusions for improving said electrical connection to said battery.

7. The battery pack of claim 1 wherein the first conductive fabric comprises an elastic type fabric.

8. The battery pack of claim 1 wherein the first and second conductive traces comprise polymeric ink having silver conductive particles.

9. The battery pack of claim 1 wherein the first fabric is attached to the second fabric by glue.

10. The battery of pack of claim 1 wherein the second fabric is Mylar and the second conductive traces comprise applied copper.

11. The battery pack of claim 1 wherein said first and second fabrics comprise a pliable backing.

12. The battery pack of claim 11 wherein said pliable backing comprises polyurethane.

13. A flexible battery pack for holding and connecting a button type battery comprising:

a first fabric having a perimeter;

a first conductive trace in juxtaposition to said first fabric;

a second fabric;

a second conductive trace in juxtaposition to said second fabric; and

wherein the first fabric is attached to the second fabric along said perimeter creating said battery pouch such that a battery when placed within battery pouch is electrically connected to said first and second conductive traces.

14. A flexible battery pack for holding and connecting a button type battery comprising:

a first felt fabric having a first pliable urethane backing and a perimeter;

a first conductive ink trace affixed said first pliable urethane backing;

a second felt fabric having a second pliable urethane backing and a slit;

a second conductive ink trace affixed said second pliable urethane backing; and

wherein said first fabric is sonically welded along said perimeter to said second fabric creating a battery pouch such that said battery can be placed into said battery pouch through said slit.

15. The battery pack of claim 14 wherein said battery is electrically connected to said first and second conductive traces when placed within said battery pouch.
