Lithium-sulfur (Li-S) batteries has been considered as one of the key technologies for the future applications such as portable electronics and EV. However, there are a few barriers to commercialize Li-S batteries. The intermediate reaction product between lithium and sulfur generates soluble polysulfide, which can be directly reduced on lithium anode to consume active material or induce “shuttling effect” between electrodes. Additionally, intrinsic insulating characteristic of sulfur decreases the utilization of sulfur and impacts on the cell performance. To resolve such problem, many researches have been focused on the modification of the cathode, electrolyte, separator, and anode that can stop or slow down the lithium polysulfide dissolution effect. polysulfide dissolution effect. In this work, we investigate the effect of polyimide-based composite binder on the PS dissolution behavior and electrochemical characteristics of Li-S batteries. |
