  abstract = {A method based on a selectivity coefficient and the
Nernst-Planck
	equation is proposed to determine diffusion coefficients of vanadium
	ions across a cation exchange membrane in VO<sup>2+</sup>/H<sup>+</sup>
	and VO<sub>2</sub> <sup>+</sup>/H<sup>+</sup> systems. This simplified
	method can be applied to high concentrations of vanadium ions. Three
	cation exchange membranes were studied. The logarithmic value of
	the selectivity coefficient was linearly dependent on the molar
fraction
	of vanadium ions in solution. The diffusion coefficient of vanadium
	ions decreased with decreasing water content. The membrane with the
	lowest diffusion coefficient was selected as a battery separator
	and showed the lowest capacity loss of the studied membranes.},
