Abstract

Porous α-Ni(OH)(2) microflowers are successfully synthesized via a one-step aqueous-phase reaction assisted by block copolymers under mild conditions. The electrochemical measurement demonstrates that the α-Ni(OH)(2) microflowers calcined at 200 °C are capable to deliver a specific capacity of 1551 F g(-1) in 6 M KOH solution, suggesting their high potential as a novel electrochemical pseudocapacitor.

摘要

多孔α-Ni(OH)(2)微花是通过在温和条件下，一步水相反应并借助嵌段共聚物成功合成的。电化学测量表明，在 200°C 下煅烧的 α-Ni(OH)(2)微花在 6 M KOH 溶液中具有 1551 F g(-1)的比容量，这表明其作为新型电化学赝电容器具有很大的潜力。
