Abstract
- Herein, porous NiMoO 4 @C nanowire is purposefully synthesized using oleic acid as carbon source, and further evaluated as high performance anode material for Li-ion batteries (LIBs). Compared with the pure NiMoO 4 , porous NiMoO 4 @C nanowire exhibits high reversible charge/discharge specific capacity, excellent cycle stability and preeminent rate capability. A stable reversible lithium storage capacity of 975 mAh g−1 can still be maintained after 100 cycles at 200 mA g−1. When the current density decreases back from 3000 mA g−1 to 100 mA g−1, a high discharge specific capacity of 884 mAh g−1 is recovered. The porous structure and carbon layers can enhance the electronic transmission and structural stability, shorten the path lengths for ion and electron transport, and provide a mechanical buffer space to accommodate the volume expansion/contraction during the repeated Li+ insertion/extraction processes. All the results highlight that the porous NiMoO 4 @C nanowire composite would be a promising candidate for high performance anode material of LIBs owing to its excellent electrochemical properties.
