Low-order, explicit models of lithium ion cells are critical for real-time battery management system (BMS) applications. This paper presents a seventh-order, electrolyte enhanced single particle model (ESPM) with electrolyte diffusion and temperature dependent parameters (ESPM-T). The impedance transfer function coefficients are explicit in terms of the model parameters, simplifying the implementation of temperature dependence. The ESPM-T model is compared with a commercially available finite volume based model and results show accurate matching of pulse responses over a wide range of temperature (T) and C-rates (I). The voltage response to 30 s pulse charge–discharge current inputs is within 5% of the commercial code for 25 °C<T<50 °C at I≤12.5C and -10 °C<T<50°C at I≤1C for a graphite/nickel cobalt manganese (NCM) lithium ion cell.

Molecular Radius

The dielectric relaxation time of rigid polar molecules in dilute solutions is shown to depend exponentially on an effective molecular radius which is independent of the solvent. This relation contains a temperature-dependent structure parameter, the coefficients of which are used to calculate the activation energy and -entropy of the rate process. The resulting entropies are now more satisfying due to a new formulation of the scattering factor.Similarly the viscosity of the solvent and its structure parameters are related by an exponential law. A characteristical length in this relation is a measure of the "hole distance" of the rate process. From both exponential laws follows that the dielectric relaxation time raised to the power of the ratio of effective molecular radius to hole distance is proportional to the viscosity of the solvent
