Surface-modified, low surface area synthetic graphite may have a BET surface from 1.0 to 4.0 m/g and a crystallite size Lto crystallite size Lratio of greater than 1. Processes for modifying the surface of low surface area synthetic graphite may result in surface-modified, low surface area synthetic graphite have a BET surface from 1.0 to 4.0 m/g and a crystallite size Lto crystallite size Lratio of greater than 1. Such synthetic graphite may have many uses, including for example, as a negative electrode material in lithium-ion batteries.

The present disclosure relates to surface-modified carbon hybrid particles in agglomerated form, methods for making such surface-modified carbon hybrid particles and their use, for example as conductive additives. The surface-modified carbon hybrid particles are characterized by a high surface area and a high mesopore content. The disclosure also pertains to methods for making dispersions of such compounds in a liquid medium in the presence of a surfactant and their use as conductive coatings. Polymer compounds filled with the surface-modified carbon hybrid particles are also disclosed. A further disclosure relates to the use of surface-modified carbon hybrid particles as carbon supports.
