A novel anode comprised of C&N co-doped Co3O4 hollow nanofibres with excellent performance for lithium-ion batteries

C&N co-doped Co3O4 hollow nanofibres are prepared by combining the electrospinning technique and the hydrothermal method, which show a high reversible capacity and excellent cycling stability as anode materials for Li-ion batteries. DFT calculations give a good explanation for the experimentally enhanced conductivity in C&N co-doped Co3O4 hollow nanofibres.
