中文摘要	hierarchical porous nickel cobaltite (nico2o4) nanomaterials were synthesized via a hard-templating route. the obtained materials consist of nanostructured cubic nico2o4 spinels and a spot of cubic nio nanoparticles, and the materials display a typical hierarchical porous structure. the nico2o4 electrode displays quasireversible dynamics characteristics, mainly faradaic capacitance behavior and capacitance relaxation feature. the nico2o4 electrode exhibits an excellent long cycling behavior with no capacitance decays during 5,000 cycles at a current density of 2 a g(-1) in 1 m koh electrolytes, and the nico2o4 electrode exhibits both high power and energy performances even after 5,000 cycles with respective value of 1,758 w kg(-1) and 8.3 w h kg(-1) in 1 m koh electrolytes, indicating that the nico2o4 nanomaterials are promising candidates for electrochemical capacitors.
