To enable the use of raw laboratory data in studies requiring the assessment of local electrolyte properties, the density and viscosity measurements were subjected to polynomial fitting using multivariable regression techniques. Below, regressions for the density, ρ j , and viscosity, ν j , of both electrolytes, j = {+, -}, are presented and discussed. The regressions are conveniently expressed as Taylor series centered around the reference values c V,0 = 0.915 M, c S,0 = 2.20 M, T 0 = 10 • C, and SoC = 0 facilitating the isolation of the effects of various parameters in distinct terms. During the derivation of the polynomial fits, terms with coefficients significantly smaller than others were neglected.
