Steric-Electronic Engineering of Ester Carbonyls Enables Thermodynamic-Kinetic Regulation of Electron Transfer for High-Voltage and High-Rate Lithium Metal Batteries.
Ester-based electrolytes, widely used in lithium-ion batteries (LIBs), suffer from the intrinsically unstable carbonyl groups that trigger uncontrollable reductive decomposition, along with the narrow operating temperature window, limiting their application in high-energy lithium metal batteries (LMBs). In this study,...
