Role of solvent-anion charge transfer in oxidative degradation of battery electrolytes

Based on computations, the authors show that voltage stability of battery electrolytes is determined not by a single component but by formation of charge transfer complexes between salt anions and solvent molecules. A physical model is proposed and validated on several common electrolyte composition...
