Abstract:
Sodium ion batteries (SIBs) have recently received significant attention as battery alternative to lithium ion batteries (LIBs), Sodium ions batteries are promising for large-scale storage applications because the abundance and very low cost of sodium-containing precursors used to make the components as compared to lithium- and the similar chemistry between the two elements. NaMnCoO4 has been prepared by novel polymeric citrate-urea route with different calcinations temperatures and evaluated as a positive electrode for sodium-ion batteries in term capacity, energy density and cycle life. Electrochemical properties measured by cyclic voltametric (CV) with 1M of NaClO4 dissolved in propylene carbonates:ethylene carbonates (1w:1w) as electrolytes and pure sodium metal as anode. structural properties were performed by scan electron microscopy (SEM), X-ray diffraction (XRD), Energy Dispersion X-ray Analysis (EDXA), Thermal Gravimetric analysis (TGA), Raman spectroscopy. The results indicates by selective controlling of the electrochemical reactions (Na ions diffusion, high Na ions interpolation) leads to improving the performance of cathode SIB.
