STRUCTURAL AND MORPHOLOGICAL INVESTIGATIONS OF SULFUR BASED CATHODE FOR LITHIUM SULFUR BATTERIES

Abstract

The Lithium–sulfur battery (Li–S battery) is a type of rechargeable battery, notable for its high energy density. Lithium–sulfur batteries may succeed lithium-ion cells because of their higher energy density and reduced cost from the use of sulfur. Lithium sulfur batteries with a higher theoretical capacity of 1672 mAhg-1
than commercial LIB systems can meet these requirements. A simple and facile synthesis route for S/PvdF/TiO2 composite via solid state reaction. The composite material has been characterized by XRD, FTIR and RAMAN Analysis. The SEM was carried out in detail to study the surface morphology and it  reveals that the sulfur is uniformly dispersed in the TiO2 matrix. From the above investigation, the composite is a favourable cathode material for lithium sulfur batteries.
