CoO/NiSi(x) core-shell nanowire arrays as lithium-ion anodes with high rate capabilities

Abstract:
This paper describes a facile chemical vapor deposition (CVD) and subsequent radio-frequency (RF)-sputtering approach for the synthesis of CoO/NiSi(x) core-shell nanowire (NW) arrays on Ni foams. The metallic core (i.e., NiSi(x)) with high conductivity acts as a nanostructured current collector. The as-synthesized CoO/NiSi(x) core-shell NW arrays have been applied as anode materials for lithium-ion batteries, which deliver high cycle life and enhanced power performance compared to planar CoO electrodes on Ni foams. The high surface-to-volume ratio and improved electronic/ionic conductivity of the nanostructured electrodes may be responsible for the improved performance.

Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...
