One step synthesis of Ni/Ni(OH)2 nano sheets (NSs) and their application in asymmetric supercapacitors

Ni/Ni(OH)₂ NSs were prepared by a facile hydrothermal method using EtOH as reducing agent. Asymmetric device is fabricated using AC and Ni/Ni(OH)₂ NSs as electrodes, with optimized specific capacitance of 62 F g⁻¹ and a maximum energy density of 23.45 W h kg⁻¹.
