Embodiment Construction

[0082] figure 1 Shown is an electrically conductive sheet 1 comprising a matrix 2 comprising fibers, at least some of which have carbon fibers. Channels 3 are formed in the base body 2 .

[0083] All fibers are carbonized.

[0084] Channel 3 is triangular in cross section.

[0085] Sheet 1 exhibited channel diameters in the range of 1-500 μm. In this sheet 1 the channels 3 have a diameter of 250 μm.

[0086] The base body 2 also comprises a first front side 4 and a second front side 5 , wherein the channel 3 forms an acute angle with the front sides 4 , 5 . In this particular embodiment the angle is less than 10°.

[0087] Furthermore, the pane 1 has a pleat-like structure, wherein the pleat edges 6 are at least partially connected to each other. The gather edges 6 are connected on one side only.

[0088] The gather edges 6 are connected to each other at least on one side of the basic body 2 by braiding, weaving and / or reinforcement. The gather edges 6 are interconnect...

Abstract

The invention relates to an electrically conductive sheet material (1, 1', 1'') which comprises a base body (2) containing fibers (9), at least part of the fibers (9) having carbon fibers. The aim of the invention is to devise an electrically conductive and flexible sheet material which has a low electrical resistance and which can be produced on a large scale in the most simple, cost-effective and reproducible manner possible. For this purpose, channels (3) extend through the base body (2).

Description

technical field [0001] The invention relates to an electrically conductive sheet according to the preamble of claim 1 . The invention also relates to a method of forming said conductive sheet. Background technique [0002] Conductive sheets, such as conductive textile sheets, are advantageous for many applications. Conductive sheets are mainly used in energy storage media, specifically for storing renewable energy (such as water conservancy, wind energy, solar radiation, geothermal) and for storing energy generated from renewable raw materials. [0003] Different types of batteries are commonly used for energy storage. These accumulators are used as primary or secondary batteries in electroplating, NaCl-electrolysis and electrolytic synthesis of inorganic materials. A primary battery refers to a battery that cannot be recharged. In view of the scarcity of fossil raw materials and the use of renewable energy, secondary batteries developed to store excess electrical energy...
