Lithium‐Sulfur Batteries: An Organodiselenide Comediator to Facilitate Sulfur Redox Kinetics in Lithium–Sulfur Batteries (Adv. Mater. 13/2021)

Redox co-mediation provides an effective approach to promote the reaction kinetics of polysulfides in lithium–sulfur batteries. In article number 2007298, Jia-Qi Huang and co-workers propose an organodiselenide as a redox co-mediator to accelerate the sulfur redox kinetics. The organodiselenide co-mediator endows lithium–sulfur batteries with superb electrochemical performance with high actual energy density of 301 Wh kg−1. This work inspires further exploration in mediating Li–S kinetics for practical high-energy-density batteries.
