RESEARCH INTEREST |
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.
