Abstract

The front cover illustration depicts the electrochemical behavior of various stainless-steel (SUS) grades in coin cells using electrolyte formulations containing lithium hexafluorophosphate (LiPF6) and lithium bis(fluorosulfonyl)imide (LiFSI) salts. The presence of chlorine ions (Cl-) as impurities in the LiFSI salt promotes localized corrosion, leading to pitting and dissolution of SUS when the cell voltage approaches 4.2 V. Such dissolution behavior is influenced by multiple factors, with the specific SUS grade and the presence of surface coatings playing critical roles in determining corrosion resistance. More details can be found in the Research Article by Marian Cristian Stan, Isidora Cekic-Laskovic, and co-workers (DOI:10.1002/celc.202400632.

期刊介绍： ChemElectroChem is aimed to become a top-ranking electrochemistry journal for primary research papers and critical secondary information from authors across the world. The journal covers the entire scope of pure and applied electrochemistry, the latter encompassing (among others) energy applications, electrochemistry at interfaces (including surfaces), photoelectrochemistry and bioelectrochemistry.
