Abstract

An apparatus may store at least one object including at least one top end and at least one bottom end. The apparatus may include a container configured to store the at least one object and a pouch containing a liquid. The pouch may be configured to substantially cover the at least one top end of the at least one object when stored inside the container. The pouch may be configured to contact the at least one top end of the at least one object and to open when contacted by contents expelled from the at least one object due to thermal runaway.

First claim

What is claimed is:

1. A container defining a cavity, the container comprising:
at least one object;
a fluid; and
at least one sealed enclosure located within the container, the sealed enclosure being defined by an outer wall, the sealed enclosure being configured to
(i) contain the fluid,
(ii) substantially cover a top end of at least one object in the container,
(iii) make contact with the top end of the at least one object, and
(iv) release the fluid when a content from the at least one object is expelled, wherein the outer wall includes at least one air pocket positioned within a thickness of the outer wall and separating the fluid and the at least one object.

2. The container of claim 1 , wherein the sealed enclosure is a pouch.

3. The container of claim 2 , wherein:
the at least one object is at least one battery; and
the sealed enclosure is further configured to release the fluid when the content from the at least one battery is expelled due to thermal runaway.

4. The container of claim 1 , wherein the sealed enclosure is a plastic bag.

5. The container of claim 4 , wherein:
the at least one object is at least one battery; and
the sealed enclosure is further configured to release the fluid when the content from the at least one battery is expelled due to thermal runaway.

6. The container of claim 1 , wherein:
the at least one object is at least one battery; and
the sealed enclosure is further configured to release the fluid when the content from the at least one battery is expelled due to thermal runaway.

7. The container of claim 1 , wherein the outer wall includes:
an inner layer in contact with the fluid; and
an outer layer disposed around the inner layer such that the at least one air pocket is formed between the inner layer and the outer layer.

8. The container of claim 1 , further including a waterproof layer disposed on an interior surface of the container.

9. The container of claim 1 , further including at least one sensor attached to the outer wall.
