Lithium-sulfur batteries have drawn interest as the battery technology beyond the lithium-ion batteries. Sulfur is an attractive cathode material in theory –its high specific capacity of 1,672mAh g-1can be used to develop batteries with a five-fold increase in energy density over the present day lithium-ion batteries (2,600 Wh kg-1 vs. 387 Wh kg-1). The abundance and low toxicity of S also impart to Li-S batteries cost benefits and environmental responsibility. However, the implementation of Li-S batteries is challenged by the dissolution of sulfur (as polysulfides)during battery operation; which results in severe capacity fading due to loss of the active material (sulfur).

I will examine the current sulfur encapsulation technologies to solve polysulfide dissolution and design the redox flow system targeting at the low electron conductivity for the Li-Sulfur battery.
