Abstract

We developed a consistent model to describe the effect of the electrochemical double-layer on the exchange reaction occurring at the interface of an electrode and a concentrated electrolyte. This model includes electrosorption, i.e. an accumulation of surface charges, and the screening of these charges within the electrochemical double-layer. We determine charges of the double-layer only from fundamental thermodynamic and electrostatic considerations, without assuming any specific structural properties of the electrolyte-electrode interface. This mathematical description is integrated in a thermodynamic consistent reaction-transport model for lithium-ion batteries (6).
