SYNTHESIS AND CHARACTERIZATION OF ANTIMONY BASED NANOSTRUCTURED COMPOSITE AS ANODE MATERIAL FOR LI-ION BATTERIES

Abstract

Lithium-ion batteries have an outstanding combination of good power density and high energy, which ultimately makes it the technology of choice for portable electronics, power tools, and hybrid/full electric vehicles. There are exciting developments in new negative electrode (Anode) materials which are based on antimony(Sb) based nanostructured composite for use in the lithium-ion batteries (LIBs) over the past decade. In this study, preparation of antimony (Sb) based nanostructured composite(Sb/TiO2/C) is done by Ball milling method. The influences on the sample are investigated by X-ray diffraction (XRD), Scanning electron microscope (SEM). X-Ray Diffraction technique result shows the proper thermodynamically stable phase formation of Sb/TiO2/C composite. The Scanning electron microscopy (SEM) shows the regular shape & distribution of fine particles along with their dense and smooth surface. Electrochemical performances for this antimony(Sb) based nanostructured composite are further analyzed
