The commercially available and widely used LP30 electrolyte was characterized via different methods to investigate thermodynamic and transport phenomena related to the salt concentration. Relevant electrolyte properties such as viscosity, conductivity, transference numbers, and diffusion coefficients of lithium ions were determined for different concentrations of conducting salt. The obtained parameters were used to set up an electrochemical model. The results show good reliability with highest ionic conductivity at 1 mol/l LiPF6 concentration. The proposed electrochemical model was simplified so that only transference numbers and conductivity are necessary for the parametrization of this electrolyte in the measured concentration range up to 2 mol/l LiPF6.
