Original Abstract

Lithium-Sulfur (Li-S) rechargeable batteries have gained a lot of attention since they have the potential to deliver high energy at low cost. However, before they can be deployed in commercial production, several problems associated with the use of a combination of sulfur and lithium metal still need to be resolved. The most significant problems include low conductivity of sulfur and its reaction products, lithium dendrite growth, sulfur electrode volume changes, and the shuttle effect. The combination of weak electronic and ionic conductivity of sulfur and its charge/discharge products with its poor electrochemical reversibility cause a relatively low-rate capability of Li-S cell. To improve the weak electrical conductivity, conductive additives, most often carbon, are added to the positive electrode material, thus reducing the sulphur content in the positive electrode volume at the expense of the conductive element. In this work, the impact of the C/S ratios on the performance of a Li-S cell is investigated.
