      abstract     = {Composites consisting of graphite and silicon have been
                      considered as potential high-capacity anode materials for
                      the next-generation Li-ion batteries (LIBs). The synthesis
                      method is critical for determining the microstructure, which
                      is directly related to the material performance and the
                      cost-efficiency for making commercial electrode materials.
                      Herein, we report the fabrication of silicon-on-graphite
                      (Si@Gr) composites by fluidized bed granulation (FBG) for
                      the first time. The FBG process is shown to produce
                      composite powders comprising a uniform layer of nano-sized
                      Si particles lodged onto the surface of micron-sized
                      graphite particles to possess a core-shell microstructure.
                      Adopting a suitable binder during the FBG process enables a
                      firm adhesion of the Si nanoparticles on graphite surface
                      during subsequent carbon-coating, where the composite
                      particles are coated with pitch and then carbonised to form
                      a highly electronically conductive and mechanical
                      stabilizing layer of amorphous carbon. These carbon-coated
                      composites exhibit a high capacity reaching over 600 mAh
                      g−1, high rate capability and illustrates the potential of
                      long-cycle stability in Si@Gr || Li metal cells, showing
                      more than $70\%$ capacity retention after 400
                      charge-discharge cycles even without electrolyte
                      optimization. Furthermore, a significantly improved cycling
                      stability is found for the carbon-coated Si@Gr materials in
                      LiNi0.6Co0.2Mn0.2O2 (NCM-622) || Si@Gr full-cells.},
