Advanced characterization techniques for understanding solid/cathode electrolyte interphase (SEI/CEI) in Li/Na ion batteries
Solid electrolyte interphase (SEI)/cathode electrolyte interphase (CEI) formed on electrode surfaces from decomposition products of liquid/solid electrolytes or reaction with liquid/solid electrolytes. The SEI/CEI allows alkaline ions transport and blocks electrons in order to prevent further electrolyte decomposition and ensure continued electrochemical reactions. This charge-transfer reactions are the foundation of current rechargeable batteries. However, the SEI/CEI has not been well understood and completely analyzed even today, which is mainly due to three reasons: (1) Uncritical trust in the obtained analysis data, without having in mind the complexity of the formed composite films and their sensitiveness to react with moisture and air and to be penetrated by the electrolyte. (2) Overemphasis of the protective properties of the SEI/CEI. (3) SEI/CEI is not fixed in chemistry and properties during cycling. This creates a need for a better understanding of the SEI/CEI formation and evolution in Li/Na ion batteries. Our collection aims to bring together a diverse range of contributions with variety advanced characterization techniques to investigate SEI/CEI. This Topical Collection will invite researchers, academics, and industry professionals to contribute their expertise, fostering a collaborative environment that drives progress and innovation to better understanding SEI/CEI. Join us delving deep into the future of electrochemical science, contributing to a more sustainable tomorrow.
