Porous Mo2N nanobelts as a new anode material for sodium-ion batteries

Abstract The limited dynamics and poor cycling stabilities of the current reported anode materials have become the bottleneck for the practical applications and development of sodium-ion batteries (NIBs). It is very urgent to explore new anode materials for NIBs. Herein, we reported a new anode material for NIBs, molybdenum nitride (Mo 2 N). The synthesized Mo 2 N with porous nanobelt shape showed a “single-crystal-like” form of simple cubic crystal, and highly porous structure. Moreover, the Mo 2 N nanobelts exhibit an excellent capacity retention ratio of more than 85% after 200 cycles and fine rate performance. We believe that such porous Mo 2 N nanobelt will be a new promising electrode active material for NIBs.
