Tailoring the Chemical/Electrochemical Response in a Quasi−Solid Polymer Electrolyte Enables the Simultaneous In Situ Construction of Superior Cathodic and Anodic Interfaces (Adv. Energy Mater. 22/2024)

Smart Electrolytes In article number 2304532, Yun Lu, Yuefeng Su, Lai Chen, and co-workers report on a quasi−solid polymer electrolyte that enables the operation of high−voltage lithium metal batteries under critical conditions by addressing the nasty interface issues. The proposed chemical/electrochemical response triggered by 18-crown-6 and LiNO3 is critical for battery performance improvement and could potentially contribute to more knowledge−driven engineering of smart electrolytes.
