Sulfur Cathode Design for Practical Lithium–Sulfur Batteries

Lithium–sulfur (Li–S) batteries are promising candidates for energy storage owing to their high theoretical energy density and low cost. However, challenges remain due to inherent issues such as sluggish redox kinetics and the severe polysulfide shuttle effect of the sulfur catho...

In Situ Sodiation of CoSe 2 Modulating Charge Transfer in Sodium−Selenium Batteries

ABSTRACT Selenized polyacrylonitrile (SePAN), characterized by the unique C−Se covalent bonds, can suppress the formation of polyselenides and their associated shuttle effect in sodium−selenium (Na−Se) batteries. However, its polymeric structure and distinct conversion mechanism...
