摘要: Abstract A facile, environmentally friendly and low-cost synthesis strategy is demonstrated to fabricate a MoO 2 /N-doped graphene (MoO /N-GNS) hybrid, in which nanoparticles (NPs) are uniformly dispersed on N-GNS sheets by Mo–N chemical bond formed between N-GNS. As an anode material lithium ion batteries, the /N-GNS hybrid possesses superior rate capability, excellent cycling performance as well high reversible capacity. capacity of 1138.5 mA h g −1 maintained after 60 cycles at current density 100 mA g , even 1000 mA g specific 873.7 mA h g can be obtained cycles. The electrochemical attributed synergistic effects nitrogen-doping, flexible conductive GNS, NPs.
