  • Publication number: 20210171353
    Abstract: The present disclosure relates to compositions comprising at least two different carbonaceous components, at least one being a surface-modified carbonaceous particulate material typically having a relatively high spring-back, and at least one other component being a carbonaceous particulate material (such as graphite) generally having a lower spring-back and/or a higher BET specific surface area than the surface-modified carbonaceous material component. Such compositions are particularly useful for making negative electrodes for lithium-ion batteries and the like in view of their beneficial electrochemical properties, particularly in automotive and energy storage applications.

  • Publication number: 20200227747
    Abstract: The present disclosure relates to a novel process for preparing isotropic carbonaceous composite particles with favorable crystallographic, morphological & mechanical properties, wherein relatively fine carbonaceous primary particles are coated with a carbonaceous binder precursor material, agglomerated and finally heat-treated at temperatures between about 1850 and 3500° C. to convert the binder precursor material to non-graphitic or graphitic carbon, thereby resulting in stable highly isotropic carbonaceous composite materials wherein the primary particles of the aggregate are held together by the carbonized/graphitized binder. The present disclosure also relates to the isotropic carbonaceous composite particles obtainable by the process described herein.

  • Patent number: 10707487
    Abstract: 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.
