Peapod-like [email protected]₂O₃ (CNT = carbon nanotube) with small V₂O₃ nanoparticles (13 nm) and a good electronic conductive network (the CNTs) was constructed through a reflux and annealing process. As anode materials, [email protected]₂O₃ shows admirable capacity (652.4 mA h g^–1 at 500 mA g^–1 for 200 cycles), a long lifespan, and good rate performance. Compared with V₂O₃, the peapod-like [email protected]₂O₃ composites have superior electrochemical performance due to the porous structure, the V₂O₃ particles, and peapod-like architecture, which reduce the transmission distance of lithium ion, enlarge the superficial area, and enhance structural stability. As a result, the unique composite material with a peapod-like structure is an ideal anode material.
