Abstract
Cobalt oxide based electrode materials are now widely used in rechargeable batteries. In this research work, Al incorporated Co(3)O(4)compositionswere chemically synthesized to study the effect of Al incorporation content on electrochemical performance of host Co3O4. Structural analysis was carried out by X-ray diffraction to observe the crystal structure and phase stability. Lattice constant, lattice strain, crystallite size, and cell volume were precisely calculated. Morphology and elemental compositions were extracted using field emission scanning electron microscopy and energy dispersive X-ray spectroscopy, respectively. Fourier transform infrared spectroscopy exhibit the O-Al-O and O-Co-O and Al-O bonding and with increasing the concentration of Al, the vibrational peaks of Co-O become sharper. Enhanced electrochemical performance as evident by cyclic voltametry was obtained in compositions with higher Al content.
