摘要：

Hierarchical mesoporous nickel hydroxide (alpha-Ni(OH)(2)) nanoparticles have been prepared by an inexpensive, simple, and green co-precipitation technique. The alpha-Ni(OH)(2)-activated carbon (AC) composite films have been fabricated onto a stainless steel substrate by the doctor blade method through the incorporation of AC into alpha-Ni(OH)(2) nanoparticles. The electrochemical performance of the composite electrode material is evaluated by varying the concentration of AC in the composite. As compared to pure alpha-Ni(OH)(2), the alpha-Ni(OH)(2)-AC composite exhibits a more specific capacitance of 436 Fg(-1) and noteworthy long-term capacitance retention of 81% after 1500 cycles. The alpha-Ni(OH)(2)-AC composite electrode materials will be the potential candidates for fabrication of next generation electrochemical supercapacitors.
