Preparation And Properties Of High Performance Molybdenum Oxide Emulsion Materials

There has been great attention to the high-performance electrode materials of Lithium-ion batteries due to their important roles in making better batteries. In this article, we successfully synthetized high-capacity molybdenum dioxide nanoparticles/graphene complex, high-capacity molybdenum trioxide nanobelts/graphene complex and mixed-valenced MoOx nanoparticles/RGO complex with much better performance. Further research indicated that even graphene-free mixed-valenced MoOx nanoparticles has excellent electrochemical performance:high capacity (more than 800 mAh·g-1); long life (more than 100 cycles) and good rate performance (about 600 mAh·g-1 at a current density of 2 A·g-1). In order to prove that the special valence is the key factor of the MoOx’s great performance, the bulk mixed-valenced molybdenum oxide has also been synthetized by reduction method. The bulk MoOx also acts well as anode materials for lithium-ion batteries. What’s more, the one-pot reduction method costs little and can be easily extended to large-scale production. The present mixed-valenced molybdenum oxide not only provides us a high-performance, low-cost, environment-friendly anode materials for lithium-ion batteries, but also show us a new method and strategy to synthetize more high-performance transition metal oxide as electrode materials for lithium-ion batteries.
