p ‐Phenylenediamine is used to successively generate two aryl radicals that are required to link silicon nanoparticles to graphite flakes by a phenyl bridge and form new silicon/graphite nanocomposites (see image). Such a covalent grafting technique enhances the cycling ability and the gravimetric capacity of the nano composite‐based electrode in a lithium‐ion battery.
