Deeper insights into electrolytes’ ionic conductivity

How do solvent molecules and anions organize themselves around the lithium in the electrolyte of a lithium-ion battery? Researchers from INAC and Liten used DFT, a computational quantum mechanical modelling method, and molecular dynamics to find answers. Their results were confirmed by vibrational spectroscopy images from the United States.

The research provided crucial insights into the influence of anions on the overall structure of the cation-solvent-anion structure and a rational explanation for the loss of ionic conductivity of electrolyte solutions at high concentrations. This new information could be used to enhance electrolyte formulations for better conductivity.
