Abstract

The present disclosure is related to articles (e.g., containers, battery packs, etc.) including a lithium material (e.g., one or more lithium-containing batteries) housed therein. The articles include sulfur hexafluoride located within an interior compartment of the article to provide an inert atmosphere within the interior compartment. The present disclosure is also related to methods of inerting such articles (e.g., containers, battery packs, etc.) with sulfur hexafluoride. Additionally, the present disclosure is related to conveyed (e.g., pumped, blown, etc.) looped cooling apparatuses and systems.

First claim

That which is claimed:

1. A method for suppressing thermal runaway in a lithium-containing device, the method comprising:
introducing a lithium-containing device that is experiencing a thermal runaway into a sealable container, wherein an interior space of the sealable container is filled with an inert gas, and
sealing the lithium-containing device in the interior space of the container, wherein the sealable container comprises a flexible bag having a sealable opening.

2. The method of claim 1 , wherein the lithium-containing device comprises a lithium-containing battery.

3. The method of claim 1 , wherein the container comprises a rigid container having a sealable lid.

4. The method of claim 1 , wherein the inert gas comprises sulfur hexafluoride.

5. The method of claim 4 , further comprising the step of reacting the sulfur hexafluoride with an electrolyte released from the lithium-containing device to produce a non-volatile lithium sulfide.

6. The method of claim 1 , wherein the interior space of the container is filled with the inert gas prior to the step of introducing the lithium-containing device into the sealable container.

7. The method of claim 1 , wherein the interior space of the container is filled with the inert gas after the step of introducing the lithium-containing device into the sealable container.

8. The method of claim 1 , wherein the container comprises a material that is anti-ballistic and/or fire-flame resistant.

9. A method for suppressing thermal runaway in a lithium-containing device, the method comprising:
introducing a lithium-containing device that is experiencing a thermal runaway into a sealable container, the sealable container comprising a flexible bag having a sealable opening,
sealing the lithium-containing device in the interior space of the container, and introducing an inert gas into an interior space of the sealed container.

10. The method of claim 1 , wherein the lithium containing device is a consumer product.

11. The method of claim 10 , wherein the consumer product is a phone, laptop, or tool.

12. The method of claim 1 , wherein the step of sealing the sealable opening comprises closing a zipper.

13. The method of claim 1 , wherein the method is performed on a vehicle.

14. The method of clam 13 , wherein the vehicle is an aircraft.

15. The method of claim 9 , wherein the lithium-containing device comprises a lithium-containing battery.

16. The method of claim 9 , wherein the inert gas comprises sulfur hexafluoride.

17. The method of claim 9 , wherein the container comprises a material that is anti-ballistic and/or fire-flame resistant.

18. The method of claim 9 , wherein the lithium containing device is a phone, laptop, or tool.

19. The method of claim 9 , wherein the step of sealing the sealable opening comprises closing a zipper.

20. The method of claim 9 , wherein the method is performed on an aircraft.
