Abstract
A layered composite material which is suitable, in particular, for use in a redox flow battery, contains at least one layer of a textile fabric and at least one graphite-containing molded body which is obtained by a method in which graphite particles are mixed with at least one solid organic additive to form a mixture and the thus obtained mixed is then compressed.

A layered composite material, comprising:
- at least one layer of textile fabric;
- and
- at least one graphite-containing molded body, said graphite-containing molded body having graphite particles mixed with at least one solid organic additive to form a mixture and the mixture obtained then being compressed.
A redox flow battery, comprising:
- a layered composite material containing at least one layer of textile fabric and at least one graphite-containing molded body, said graphite-containing molded body having graphite particles mixed with at least one solid organic additive to form a mixture and the mixture obtained then being compressed;
- an electrolyte;
- and
- a membrane.
A bipolar plate for use in a redox flow battery, the bipolar plate comprising:
- at least one solid organic additive;
- and
- graphite particles mixed with said at least one solid organic additive forming a mixture and said mixture being compressed, said mixture to be compressed containing 0.5 to 50 wt. % of said solid organic additive and a remainder being said graphite particles being particles of expanded graphite.
A production method, which comprises the steps of:
- providing a layered composite material containing at least one layer of textile fabric and at least one graphite-containing molded body, the graphite-containing molded body having graphite particles mixed with at least one solid organic additive to form a mixture and the mixture obtained being compressed;
- and
- producing a redox flow battery or a stack of several adjacent redox flow cells from the layered composite material.
