Abstract

Mesoporous nickel oxide has been synthesized by calcining metal-organic coordination precursor.Transmission electron microscopy and BET test showed that the prepared NiO had a regular morphology and displayed a narrow size distribution.Electrochemical tests revealed that such mesoporous NiO had a specific capacity of 72 F·g-1 at the current of 2.0 A·g-1.Futhermore,the material showed excellent cycle-life stability.There was no degradation of capacitance after 1000 cycles.
