α-MoO3 nanobelts and PEO surfactant MoO3 nanobelts were synthesized using simple hydrothermal method. The PEO surfactant MoO3 nanobelts have high specific capacity at the nineth cycle (64.2%) compared to pure MoO3 nanobelts (58.9%). The 12.5 wt% PEO surfactant MoO3 nanobelts show better stabilized specific capacity (218 mAhg-1) at the 25th cycle which is more than the pure MoO3 nanobelts (198 mAhg-1). α-MoO3 nanobelts and PVP surfactant...
