Polyvinyl alcohol-assisted synthesis of porous MoO2/C microrods as anodes for lithium-ion batteries

In this study, porous MoO2/C hybrid microrods were successfully fabricated through a simple sol-gel method. To this end, poly (vinyl alcohol) was used as a carbon source to commendably increase the conductivity and stability. The morphology and structure characterizations illustrated the porous MoO2/C microrods, which MoO2 nanoparticles were encapsulated in amorphous carbon. This special structure might be useful for facilitating Li-ions transportation. The electrochemical tests showed MoO2/C anode to possess high initial discharge specific capacity (610 mAh g−1, 0.05 A g−1) and fascinating rate capability (314 mAh g−1, 2 A g−1). Furthermore, MoO2/C electrode exhibited 81% capacity retention after 500 cycles at 1 A g−1. Overall, the porous MoO2/C hybrid microrods are prospective candidates for LIBs anode materials.Graphical abstract
