Using a battery pack to facilitate thermal transfer in a portable electronic device

1. A battery pack, comprising:

a battery cell; and

an enclosure material that forms a pouch which is sealed to enclose the battery cell and an associated electrolyte;

wherein the enclosure material extends beyond a seal for the pouch to facilitate thermal transfer within a portable electronic device containing the battery cell.

2. The battery pack of claim 1 , wherein facilitating thermal transfer within the portable electronic device involves at least one of:

using the enclosure material to dissipate heat from a component in the portable electronic device; and

using the enclosure material to dissipate heat from the battery cell.

3. The battery pack of claim 2 , wherein the enclosure material dissipates heat from the component by covering the component.

4. The battery pack of claim 3 , wherein heat is further dissipated from the component by thermally bonding the enclosure material to the component using at least one of a thermal interface material (TIM) and an adhesive.

5. The battery pack of claim 2 , wherein the component is at least one of a processor, a power supply unit (PSU), a backlight, a charging circuit, a printed circuit board (PCB), a hard disk drive (HDD), and a radio transceiver.

6. The battery pack of claim 1 , wherein the enclosure material comprises:

an internal layer;

a conducting layer; and

an external layer.

7. The battery pack of claim 6 ,

wherein the internal layer is a heat-sealable polymer and the external layer is nylon, and

wherein the conducting layer is copper, silver, or graphite.

8. A method for facilitating use of a portable electronic device, comprising:

obtaining a battery cell;

enclosing and sealing the battery cell an associated electrolyte in a pouch formed by enclosure material to create a battery pack, wherein the enclosure material extends beyond a seal for the pouch; and

arranging the battery pack within the portable electronic device so that the extension of the enclosure material is located in proximity to other components in the portable electronic device to facilitate thermal transfer within the portable electronic device.

9. The method of claim 8 , wherein facilitating thermal transfer within the portable electronic device involves at least one of:

using the enclosure material to dissipate heat from a component in the portable electronic device; and

using the enclosure material to dissipate heat from the battery cell.

10. The method of claim 9 , wherein the enclosure material dissipates heat from the component by covering the component.

11. The method of claim 10 , wherein heat is further dissipated from the component by thermally bonding the enclosure material to the component using at least one of a thermal interface material (TIM) and an adhesive.

12. The method of claim 9 , wherein the component is at least one of a processor, a power supply unit (PSU), a backlight, a charging circuit, a printed circuit board (PCB), a hard disk drive (HDD), and a radio transceiver.

13. The method of claim 8 , wherein the enclosure material comprises:

an internal layer;

a conducting layer; and

an external layer.

14. The method of claim 13 ,

wherein the internal layer is a heat-sealable polymer and the external layer is nylon, and

wherein the conducting layer is copper, silver, or graphite.

15. The method of claim 8 ,

wherein the enclosure material forms a pouch which surrounds the battery cell, and

wherein the enclosure material extends beyond a seal for the pouch.

16. A portable electronic device, comprising:

a set of components powered by a battery pack; and

the battery pack, comprising:

a battery cell; and

an enclosure material that forms a pouch which is sealed to enclose the battery cell and an associated electrolyte,

wherein the enclosure material extends beyond a seal for the pouch to facilitate thermal transfer within a portable electronic device containing the battery cell.

17. The portable electronic device of claim 16 , wherein facilitating thermal transfer within the portable electronic device involves at least one of:

using the enclosure material to dissipate heat from a component in the portable electronic device; and

using the enclosure material to dissipate heat from the battery cell.

18. The portable electronic device of claim 17 , wherein the enclosure material dissipates heat from the component by covering the component.

19. The portable electronic device of claim 18 , wherein heat is further dissipated from the component by thermally bonding the enclosure material to the component using at least one of a thermal interface material (TIM) and an adhesive.

20. The portable electronic device of claim 17 , wherein the component is at least one of a processor, a power supply unit (PSU), a backlight, a charging circuit, a printed circuit board (PCB), a hard disk drive (HDD), and a radio transceiver.

21. The portable electronic device of claim 16 , wherein the enclosure material comprises:

an internal layer;

a conducting layer; and

an external layer.

22. The portable electronic device of claim 21 ,

wherein the internal layer is a heat-sealable polymer and the external layer is nylon, and

wherein the conducting layer is copper, silver, or graphite.

23. The portable electronic device of claim 16 , wherein the battery cell is at least one of a lithium-ion battery cell and a lithium-polymer battery cell.
