Nickel Foam-Supported NiO/Ag Porous Spheres Prepared by Electrodeposition as Anode for Lithium-Ion Batteries

Abstract:

Article Preview

Nickel foam-supported NiO spheres were prepared by an electrodeposition technique using nickel foam as the substrate, and then the Ag nanoparticles were loaded on the NiO spheres. SEM images showed that these NiO/Ag spheres are porous with a size of about 2 µm. As an anode for lithium-ion batteries, the nickel foam-supported NiO/Ag spheres exhibit higher coulombic efficiency, weaker polarization, and better cycling performance as compared to the NiO spheres. The improvements of these electrochemical properties are attributed to the Ag nanoparticles, which enhanced the electrical conduction of the electrode.
