Abstract

A structural component for a vehicle has a battery construction having a solid-electrolyte matrix material, a first layer of carbon fibres having a cathode-active coating, embedded in said solid-electrolyte matrix material, a second layer of carbon fibres without a cathode-active coating, embedded in said solid-electrolyte matrix material, and at least one electrically isolating barrier layer disposed between said first layer and said second layer. The structural component has a first collector layer and a second collector layer disposed on the first layer and the second layer, respectively, on a side that faces away from the barrier layer. The first collector layer and the second collector layer are configured from a flexible, moldable and porous layer of carbon allotropes.

First claim

What is claimed is:

1. A structural component for a vehicle, comprising:
a battery construction having a solid-electrolyte matrix material;
a first layer of carbon fibres having a cathode-active coating, embedded in said solid-electrolyte matrix material;
a second layer of carbon fibres without a cathode-active coating, embedded in said solid-electrolyte matrix material;
at least one electrically isolating barrier layer disposed between said first layer and said second layer; and
a first collector layer and a second collector layer which are disposed on the first layer and the second layer, respectively, on a side that faces away from the barrier layer, wherein the first collector layer and the second collector layer are each configured from a flexible, moldable and porous layer of carbon allotropes.

2. The structural component according to claim 1 , wherein at least one of the collector layers comprises carbon nanotubes which are embedded in the matrix material or form a woven fabric.

3. The structural component according to claim 2 , wherein at least one of the collector layers is configured from a porous mat of non-woven carbon nanotubes.

4. The structural component according to claim 1 , wherein the cathode-active coating comprises LiFeO 2 .

5. The structural component according to claim 1 , wherein the barrier layer comprises non-conducting fibres.

6. The structural component according to claim 1 , wherein the barrier layer comprises carbon fibres which have an insulating coating.

7. The structural component according to claim 1 , further comprising at least one additional structural layer which covers the battery construction at least on one side and reinforces the structural component.

8. The structural component according to claim 1 , wherein the collector layers are each equipped with at least one electrical connector member, wherein all connector members extend to the same side of the battery construction.

9. A vehicle having at least one structural component according to claim 1 .

10. The vehicle according to claim 9 , wherein the vehicle is an aircraft.
