Patent ID: 7182887

Claim:
Conducting composite material composed of a kneaded and compressed mix, the mix comprising a flake graphite powder, conducting fibres and an organic binder, the mix comprising: from 40 to 90% by volume of a flake graphite powder comprising a first flake graphite type formed from lamellas with a size grading of between 10 and 100 μm, and a second flake graphite type formed by agglomerating graphite particles such that the graphite particles are bonded to each other and superposed such that their principal planes are parallel to each other, these agglomerates having a planar anisotropy with side dimensions between 10 μm and 1 mm and between 5 and 50 μm thick, from 0 to 25% by volume of conducting fibres, and from 10 to 40% by volume of an organic binder.
