Abstract:
The high cost and scarcity of lithium are driving research to develop alternatives to lithium-ion batteries (LIBs); the sodium ion battery (SIB) presents a promising candidate for an alternative battery, due to the abundance and the low cost of Na. Different types of Co3O4 nanostructures were prepared by co-precipitation at different temperatures. Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), Energy dispersive X-ray Analysis (EDAX), and Raman Spectroscopy were used to characterize the obtained nanoparticles. These structures were used as anodes to improve the electrochemical performance of SIBs in terms of energy density and capacity by selectively controlling oxidation and reduction reactions. Cyclic voltammetry (CV) was used to determine the electrochemical properties of each material as anodes in SIBs.
