Study for the enhanced energy storage properties of α-MoO3 microstructures in lithium ion batteries

Orthorhombic alpha-MoO3 is one thermodynamically multifunctional material and presents significant performance in lithium-ion batteries. It is interesting to prepare alpha-MoO3 structures through a facile method that can deliver a high reversible capacity and excellent capacity retention. In this study, two alpha-MoO3 samples with sheet-like structure and strip-like structure were prepared and utilized as anodes of Li-ion batteries. The Li+ insertion-extraction process and storage performance were studied. After 400 cycles, the reversible capacity of the sheet-like alpha-MoO3 microstructure and strip-like alpha-MoO3 microstructure was maintained at 1064.7 and 1143.4 mA h g(-1) at a current density of 0.5 A g(-1). Furthermore, the strip-like alpha-MoO3 microstructure can deliver a stable specific capacity of 554.4 mA h g(-1) at a current density of 5.0 A g(-1). The excellent reversible capacity and cycling capability suggest that strip-like alpha-MoO3 microstructures present promising applications in lithium ion batteries.
