Abstract
A Co3O4/N-doped reduced graphene oxide (N-doped GN) nanocomposite was successfully synthesized by a facile freeze-drying method and heat-treated subsequently. When used as an anode material for lithium ion batteries (LIBs), the composite showed superb cycling stability and rate performance. More remarkably, the Co3O4/N-doped GN composite achieved an ultrahigh reversible capacity of 950 mA h g−1 exceeds the theoretical capacity (890 mA h g−1) of Co3O4 after 100 cycles at a current density of 0.2 A g−1, which made it a promising anode material for LIBs. Therefore, the nanocomposite can be deemed to be potential candidates as anode materials for further investigation.
