摘要：

Porous nickel oxide nanospindles have been successfully synthesized by calcining a coordination complex precursor in air. The electrochemical test shows that the porous nickel oxide nanospindle electrode with an excellent specific capacitance reached a surprisingly high 1609 F g(-1), and remained more than 83.3% after 3000 cycles at 10 A g(-1). The excellent performance of the porous nickel oxide nanospindles suggests its promising application in supercapacitors.
