Zusammenfassung:	The present disclosure relates to a novel surface-modified carbonaceous particulate material having a hydrophilic non-graphitic carbon coating. The material can for example be produced by CVD-coating of a carbonaceous particulate material such as graphite followed by an oxidation treatment under defined conditions. The resulting material exhibits a more hydrophilic surface compared to an unmodified CVD-coated carbon material, which is desirable in many applications, such as when used as an active material in the negative electrode of lithium ion batteries or in a polymer composite material.
