AI Article Synopsis
- MoS quantum dots (QDs) are used as electrolyte additives in lithium-sulfur batteries to stabilize soluble polysulfides through chemisorption.
- They enhance the conversion of sulfur compounds by facilitating electrocatalysis, improving the battery's performance.
- Batteries with MoS QDs demonstrate significantly higher retained capacity and better high-rate capability compared to those without them.
Article Abstract
Herein, MoS quantum dots (QDs) are constructed to serve as electrolyte additives for lithium-sulfur batteries, which can 'solidify' soluble polysulfides by chemisorption and promote sulfur conversion chemistry by electrocatalysis. The Li-S cell with MoS QDs shows high retained capacity and high-rate capability, much better than the counterpart without MoS QDs.
