Decoding Cathode-Electrolyte Interface Issues in Conventional Ethers Electrolytes-Based Magnesium Rechargeable Batteries
Abstract
Magnesium rechargeable batteries (MRBs), as a promising candidate for next-generation high-energy batteries, offer inherent advantages in terms of resource availability and safety. To identify the key factors for achieving high-voltage MRBs, this study ether-based weakly coordinating anion (WCA) electrolytes—Mg[B(OCH(CF3)2)4]2 (BHFIP) and Mg[Al(OCH(CF3)2)4]2 (AlHFIP)— are investigated under varying water content to elucidate their electrochemical behavior on carbon-coated Al current collectors and MnO2 cathodes. The two electrolytes are found to exhibit different characteristics in moisture, but as a common conclusion, trace water can promote electrolyte decomposition and CEI formation. Ultimately,….
