Facile and Eco-Friendly Synthesis of Finger-Like Co?O? Nanorods for Electrochemical Energy Storage.

ABSTRACT: Co?O? nanorods were prepared by a facile hydrothermal method. Eco-friendly deionized water rather than organic solvent was used as the hydrothermal media. The as-prepared Co?O? nanorods are composed of many nanoparticles of 30-50 nm in diameter, forming a finger-like morphology. The Co?O? electrode shows a specific capacitance of 265 F g-1 at 2 mV s-1 in a supercapacitor and delivers an initial specific discharge capacity as high as 1171 mAh g-1 at a current density of 50 mA g-1 in a lithium ion battery. Excellent cycling stability and electrochemical reversibility of the Co?O? electrode were also obtained.
