Abstract

A transport device for lithium batteries in an aircraft, in particular in a hold, includes a container and a lid, lithium batteries being arranged in the container and the lid closing the container during transport of the lithium batteries. A shutoff valve neutralizes electrolyte released by the lithium batteries within the container or conveys the electrolyte to the outside.

First claim

What is claimed is:

1. A transport device for lithium batteries in an aircraft comprising:
a container;
lithium batteries arranged in the container;
a lid closing the container during transport of the lithium batteries; and
a shutoff valve configured to neutralize electrolyte released by the lithium batteries within the container, or configured to convey the electrolyte outside,
wherein the container comprises separators which comprise a thermally and chemically resistant material.

2. The transport device of claim 1 , wherein the released electrolyte is neutralized by a catalyst arranged upstream of the shutoff valve.

3. The transport device of claim 1 , wherein the released electrolyte is conveyed to the outside by a line connected to the shutoff valve.

4. The transport device of claim 1 , wherein the shutoff valve is configured to stop fresh air from entering the container.

5. The transport device of claim 1 , wherein the released electrolyte can be attributed to thermal runaway of at least one of the lithium batteries and pressure building up in the container can be discharged to the outside by the shutoff valve.

6. The transport device of claim 1 , wherein the container and the lid comprise a fire-resistant material.

7. The transport device of claim 1 , wherein the separators divide an interior of the container into at least two compartments.

8. The transport device of claim 1 , wherein the shutoff valve comprises a pressure sensor configured to measure pressure building up within the container.

9. The transport device of claim 1 , wherein the shutoff valve is arranged on a side face of the container.

10. A hold of an aircraft, comprising a transport device for lithium batteries, the transport device comprising:
a container;
lithium batteries arranged in the container;
a lid closing the container during transport of the lithium batteries; and
a shutoff valve configured to neutralize electrolyte released by the lithium batteries within the container, or configured to convey the electrolyte outside,
wherein the container comprises separators which comprise a thermally and chemically resistant material.

11. The transport device of claim 1 , wherein the separators comprise silicon dioxide.
