摘要

MoO _(3) is one of the most promising electrodes for high energy density supercapacitors due to its layered structure, which facilitates the insertion/removal of small ions. However, the commercial recognition of MoO _(3) -based electrodes has been hampered by their low electronic conductivity, poor structural stability and narrow working potential window. A MoO _(3) /C composite (MCs) has been synthesized by a polymerization method followed by calcination of the obtained hydrogel. The obtained MCs electrode exhibits remarkable electrochemical performance in both aqueous (432.5 F g ~(?1) at a current density of 0.5 A g ~(?1) , 100% capacity retention after 10?000 cycles) and all-solid (220.5 F g ~(?1) at 0.5 A g ~(?1) ) systems with porous C as the positive electrode, demonstrating its potential in commercial utilization.
