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...
