3D red phosphorus/sheared CNT sponge for high performance lithium-ion battery anodes

A 3D sheared carbon nanotube sponge confined red P (P-SCNT) composite is prepared via vaporization condensation technique, showing high capacity and long cyclability as anodes for LIBs. The as-prepared P-SCNT electrode delivers ultrahigh capacities of 1600 mAh g−1 at 100 mA g−1 and stable cycle performance, which owes to the robust bracing SCNT frameworks and stable chemical bonds between even-distributed red P and SCNT.463
