Abstract
The present disclosure relates to novel particulate composite materials comprising a graphitic core particle associated with SiOx nanoparticles (0.2≤X≤1.8), and coated by a layer of non-graphitic carbon, e.g., pyrolytic carbon deposited by chemical vapor deposition (CVD). Also included are processes for making such particles as well as uses and downstream products for the novel composite material, in particular as an active material in negative electrodes in Li-ion batteries.
