Abstract

In article number 2302486, Martin Winter, Masoud Baghernejad, and co-workers investigate the complementary effect of fluoroethylene carbonate (FEC) and ethoxy(pentafluoro) cyclotriphosphazene as additive compounds in an aprotic organic electrolyte in NCM523 II SiOx/C pouch cells. The authors discuss a novel property of FEC, here called molecular-cling-effect (MCE) and verified it with multiple analysis techniques. Also they thoroughly discuss the electrochemical impact of the additives on the cell performance and the relevant underlying reaction mechanisms.
