摘要

Long-term cycle performance is a key factor for the supercapacitors that used pseudocapacitivematerials. It is known to all that the morphology structures have direct influences on theelectrochemical performance of the supercapacitors. In this work, shape-controlled Co 3 O 4 electrodematerials are successfully prepared and used as electrode materials for the supercapacitors. Thedifferent morphologies are Co 3 O 4 nano-spheres and Co 3 O 4 nano-rods, respectively. Among these twoCo 3 O 4 electrode materials, the Co 3 O 4 nano-spheres shows more excellent electrochemicalperformance, with 96% capacity retention after 5000 cycles at the high current density of 5 A g -1 .
