Coated graphite particulate material

Abstract

The present invention relates to novel coated graphite particulate materials comprising graphite particles coated with a layer of amorphous carbon, wherein the coated graphite particulate materials are characterized by a particle size distribution (PSD) with a D50 of at least about 20 μm, a BET specific surface area (BET SSA) of less than about 3.0 m2/g and a crystallographic Lc value of at least about 210 nm. The present invention also provides methods for making the coated graphite particulate material, as well as polymer composite compositions comprising said coated graphite particulate materials. The invention further relates to bipolar plates and downstream products such as fuel cells including the bipolar plates which comprise said coated graphite particulate materials.
