The eminent global energy crisis and growing ecological concerns in the past two
decades have led to intensive development in the fields of green transportation such as electric and hybrid
electric vehicles (HEV), as well as clean energy sources such as wind and solar power. These technologies
demand low cost, safe, and environmentally friendly energy storage systems. Therefore, development
of novel economically feasible and ecologically friendly high performance batteries is crucial. Lithium/
sulfur (Li/S) batteries have the highest energy density (2600 Wh/kg) and theoretical capacity (1672
mAh/g) among all known systems [1,2]
