Coaxial three-dimensional CoMoO4 nanowire arrays with conductive coating on carbon cloth for high-performance lithium ion battery anode
Nanostructured transition metal oxides have attracted considerable attentions for both high-capacity and high-rate, but great challenges remain to utilize them. In order to overcome these challenges, hierarchical three-dimensional CoMoO4/polypyrrole core-shell nanowire (NW) arrays on flexible and conductive carbon cloth (CC) have been successfully constructed through a facile two-step solutionbased approach. The hybrid NWs electrode as a binder-free lithium ion batteries (LIBs) anode material exhibits a reversible capacity of around 1400-1450 mAh g(-1) at a low current density of 100 mA g(-1). The specific capacity retains at 753 mAh g(-1) while featuring an excellent cycling properties with a capacity of 764 mAh g(-1) after 1000 cycles under the current rate of 1200 mA g. Furthermore, full batteries have been fabricated and demonstrated characteristics of outstanding electrical stability and superior power output characteristics, which represents an efficient way for practical implementation.
