Enhanced charge transfer kinetics at the electrode/electrolyte interface in acetonitrile solvent for lithium-ion battery cathodes

Abstract

Acetonitrile is a low-viscosity solvent that can enhance charge transfer kinetics at the electrode/electrolyte interface, although its cathodic instability limits its demonstration. This study employed a dual-compartment cell separated by a solid electrolyte to demonstrate that an acetonitrile-based electrolyte enhanced the interfacial charge transfer kinetics compared to those of carbonate-based electrolytes.
