Nickel oxide film with open macropores fabricated by surfactant-assisted anodic deposition for high capacitance supercapacitors

Abstract

Nickel oxide film with open macropores prepared by anodic deposition in the presence of surfactant shows a very high capacitance of 1110 F g⁻¹ at a scan rate of 10 mV s⁻¹, and the capacitance value reduces to 950 F g⁻¹ at a high scan rate of 200 mV s⁻¹.
