合成5种孔径大小分布的NiO样品，测定各NiO电极在3mol/L KOH或其添加K3[Fe(CN)6]的电解液中的电化学电容性能.结果表明，NiO电极孔径分布在15nm左右，可有效减慢铁氰酸根离子向液相的扩散，从而提高N4 (NiO)电极的充放电效率.

In this paper, five kinds of NiO samples with different pore size distributions were synthesized .The electrochemical capacitance of the samples were characterized in 3 mol/L KOH solution with and without hexacyanoferrate addition. Electrochemical test results indicated the NiO sample with an optimum pore size of about 15 nm shows high Coulombic efficiency of the N4(NiO) electrode as the redox reaction of hexacyanoferrate ions would be limited in the pore, thus prevent ion diffusion into the bulk electrolyte solution .
