3D hierarchical integrated carbon/red phosphorus/graphene aerogel composite is fabricated via an advanced vapor-redistribution technique. The red P nanoparticles (10–20 nm) in the composite uniformly distribute in the carbon covered graphene aerogel matrix (C@GA), which integrated into a 3D porous structure. The as-prepared C@P/GA electrode delivers a capacity of 1095.5 mA h g−1 after 200 cycles at 1 C (1 C = 2600 mA g−1).
