Probe Growth and Degradation of SEI at Multivalent Battery Systems

Solid Electrolyte Interface (SEI) has not been widely reported for multivalent battery systems. Question such as whether there’s a SEI growth at the interface of the metal anode and the multivalent electrolytes is unclear. How the SEI is formed and its evolution with the electrochemical process is not known. Our lab has spent a great deal of efforts of understanding the role of SEI, its composition and evolution for multivalent electrolyte systems, and this work aims to give an overview of the recent research efforts with the use of the operando electroanalytical methods that reveal the SEI evolution for multivalent battery designs.
