"Modelling Lithium Battery Electrolytes and Solid Electrolytes Interphases"
Tailoring electrolyte electrochemical properties is critical for stabilizing the electrode – electrolyte interfaces and enabling novel electrochemical couples in lithium batteries. The rational design of an electrolyte requires not only the knowledge of the limits of electrolyte electrochemical stability and electrolyte decomposition reactions that might or might not occur at the surface of the electrode but also understanding of the structure and transport properties of the passivation film formed at the anode and/or cathode surfaces. I will discuss application of the molecular modelling methodologies to predict electrolyte electrochemical stability, decomposition reactions at electrodes, initial stages of the passivation layer formation and its properties.
When combined with accurate predictions of the electrolyte structure, such calculations provide tremendous insight into the mechanism of the in-situ formation of a highly beneficial passivation layer on electrodes that enable a wide range of electrode couples from lithium metal to conversion cathodes in non-aqueous electrolytes. Molecular modelling of the electrolyte structure and SEI formation mechanism enabling high energy density electrode couples in electrolytes will be discussed.
