Patents Assigned to RAIN CARBON BVBA
  • Publication number: 20250051647
    Abstract: The present invention is directed to coating material for coating primary particles, said coating material comprising a petroleum-derived pitch product, characterized in that said pitch product has a melt viscosity index log10 (visc)*100/SPM between 1.2 and 3.0 at 220° C. and between 1.0 and 2.5 at 240° C., wherein visc=melt viscosity (mPa·s) and SPM=Mettler softening point ° C. The present invention is directed as well to the use of said coating material to coat the primary particles of electrode materials in the manufacturing of battery electrodes, more specifically Li-Ion batteries. Further, the present invention is directed to a battery electrode comprising a coating made of said coating material, as well as directed to a battery comprising an electrode having a coating made of said coating material.

  • Publication number: 20240182789
    Abstract: A pitch product having a petroleum-derived distillation residue and a coal tar-derived distillation residue, said pitch product characterized by a concentration of at least 84% asphaltenes (SARA). Further, the present invention is directed to a pitch binder including said pitch product useable in manufacturing of graphite electrodes for electric arc furnaces, and carbon anodes and Soederberg paste for aluminum production. The present invention is further directed also to a graphite electrode having said pitch binder, as well as to a carbon anode comprising said pitch binder. The present invention also provides a process for producing a pitch product including a petroleum-derived distillation residue and a coal tar-derived distillation residue, said process including a petroleum vacuum distillation process step for obtaining said petroleum-derived distillation residue, and a process for manufacturing a graphite electrode or a carbon anode including said process for producing a pitch product.
