Abstract

Efforts were taken to fabricate a cathode material having Sulfur as the active material. First step is composed of identifying potential ways of fabricating a stable and efficient platform for cathode using Reduced Graphene Oxide and activated Multiwall Carbon Nanotubes. The characteristics of those materials are not subjected to detailed discussions, but their synthesis processes are described and results are shown. Some of the previously attempted works on fabricating a Sulfur cathode material are also reattempted in the lab and their results are also shown. Here, a chemical approach is taken rather than physical approach to develop a Sulfur cathode material. A new approach is attempted to fabricate a Sulfur cathode material using Organo Sulfur compounds. Fabricated Sulfur cathodes were tested with respect to Lithium anode and Discharging/Charging curves, Cyclic Voltammetry and voltage variation upon charging/discharging are analyzed.
