- the fibers may e.g. Carbon fibers, aramid fibers and / or glass fibers include. Carbon fibers are particularly preferred. Alternatively, the fibers can also
- Natural fibers include, for example, flan fibers or flax fibers.
- the graphite foil and fibers may be incorporated into a layer of composite material.
- the composite material is a laminar composite material comprising a fibrous layer and a graphite foil layer.
- the fibers are then arranged in the fiber layer and the graphite foil is arranged in the graphite foil layer.
- Laminated composite materials are preferred composite materials according to the invention, since they can be produced in a particularly simple manner by applying a graphite foil to a fibrous layer, e.g. sticking.
- the thickness of the fiber layer may be e.g. 0.5 to 5 mm, preferably 0.8 to 4 mm, particularly preferably 1 to 3 mm.
- the fibers e.g. the fibrous layer
- the flask may e.g. be selected from thermoplastics and thermosets such as epoxy resins and phenolic resins.

- One or more layers of graphite foil may be applied before or after any necessary flashing of the CFRP formed in the desired shape to obtain the layered composite comprising the fibrous layer and the graphite foil layer.
- the fibers in one part of the surface of the layered composite material are substantially completely surrounded by the flask and attached to the graphite foil in another part of the surface of the composite layer material only over the surface of the fibrous layer.
- the layered composite material comprises a fibrous layer and a graphite foil layer.
- the graphite foil layer faces the energy store and the fiber layer faces away from the energy store. This increases the passive cooling ability, since heat then passes unhindered from the energy storage in the graphite foil.
- the layered composite material may comprise further layers, e.g. a further fiber layer on the energy storage side facing the graphite foil layer.
- the further fibrous layer is preferably very thin, e.g. 0.02 to 3 mm thick, preferably 0.05 to 2 mm thick, so as not to complicate the transfer of heat from the energy storage in the graphite foil layer unnecessarily.

- the area specified here refers to one of both sides of the laminate material. It can be easily determined with the aid of a measuring tape and simple calculations. This is advantageous because then with a few attachment points large area
- Battery modules can be protected continuously throughout. This also simplifies assembly and increases manufacturing efficiency.
- the area can be calculated from a 3D scan of the laminate material. The area which is occupied by any openings of the layered composite material is included in the area of the layered composite material.
- Openings extend from one side to the other side of the laminate material and serve to secure the laminate material
- a particularly preferred layered composite material comprises a further
- Fiber layer on the other side of the graphite foil layer At a
- the graphite foil layer is arranged between two fiber layers.
- the thickness would therefore be measured here from a surface of the one fiber layer facing away from the graphite foil layer to a surface of the other fiber layer facing away from the graphite foil layer.

- the graphite foil layer has a plurality of openings.
- the arrangement of the apertures preferably defines a repeating pattern of apertures and inter-apertured graphite foil layer portions.

- the ratio of the area occupied by the openings to the base area of the graphite foil layer is preferably in the range of 0.01 to 0.98, more preferably in the range of 0.05 to 0.90; very particularly preferably in the range from 0.10 to 0.85.
- the base area of the graphite foil layer is understood to be the area occupied in the repetitive pattern by the openings and the intervening graphite foil layer sections as a whole. It thus corresponds to the area of one side of the graphite foil layer before the openings are introduced.
- the ratio of the area occupied by the openings to the base area of the graphite foil layer should be small if a high thermal conductivity in the graphite foil layer is desired.
- the basis weight of the composite material can be reduced. In particular, when the ratio of the area occupied by the openings to

- the openings can have any shape. They can, for example, be triangular, quadrangular, pentagonal, hexagonal, round or oval. In preferred embodiments, the openings are round. Round openings are particularly easy to stan- zen, which promotes a particularly efficient production of the composite layer.
- the area of each individual opening can be, for example, in the range from 0.1 mm 2 to 400 mm 2 , preferably in the range from 0.2 mm 2 to 100 mm 2 .
- a layer composite material according to the invention at least part of the openings is at least partially filled with resin.

- the fiber layer is directly connected to the optional further fiber layer.
- the carbon fibers used can contain different numbers of individual filaments. For example, from 1000 (1 k fibers) to 320 000 individual filaments (320 k fibers). Preferably, the carbon fibers have 1000 (1k fibers) to 10,0000 single filaments (10k fibers), e.g. about 3,000 individual filaments (3k fibers).
- the composite material serves to protect an energy store which heats up during charging and / or discharging.
