The present disclosure relates to novel carbon black materials characterized by a good retention of their structure in the compressed state, as shown, e.g., by a relatively high ratio of compressed OAN/OAN. The materials may inter alia be characterized by a low viscosity in dispersions and by exhibiting low electrical resistivity. Such materials can be advantageously used in various applications, for example in the manufacture of electrochemical cells such as lithium ion batteries or as conductive additive in polymer composite materials. The disclosure also describes a procedure for making such a material as well as well as downstream uses and products comprising said carbon black material.

High-conductive carbon black with low viscosity

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.
