N‐doped mesoporous carbon‐capped MoO 2 nanobelts (designated as MoO 2 @NC) were synthesized and applied to lithium‐ion storage. Owing to the stable core–shell structural framework and conductive mesoporous carbon matrix, the as‐prepared MoO 2 @NC shows a high specific capacity of around 700 mA h g −1 at a current of 0.5 A g −1 , excellent cycling stability up to 100 cycles, and superior rate performance. The N‐doped mesoporous carbon can greatly improve the conductivity and provide uninhibited conducting pathways for fast charge transfer and transport. Moreover, the core–shell structure improved the structural integrity, leading to a high stability during the cycling process. All of these merits make the MoO 2 @NC to be a suitable and promising material for lithium ion battery.
