Synthesis of nitrided MoO2 and its application as anode materials for lithium-ion batteries
چکیده انگلیسی

Nitrided MoO2 has been synthesized by hydrothermal processing followed by post-nitridation with NH3 and investigated as alternative anode materials for rechargeable lithium batteries. Characterization data reveal the presence of molybdenum nitride (γ-Mo2N and δ-MoN) and molybdenum oxynitride (MoOxNy). The nitrided MoO2 exhibits a capacity of >420 mAh/g after 100 cycles and good rate capability. The improved electrochemical performance of the nitrided MoO2 compared to that of molybdenum oxide (MoO2) is attributed to high electrical conductivity provided by nitrogen doping/or substitution in the oxygen octahedral site of MoO2 structure.


► Synthesis of nitrided molybdenum oxide by nitridation.
► Superior cyclability for nitrided molybdenum oxide anodes.
► Electrochemical reaction behavior of nitrided molybdenum oxide with lithium.
