Inorganic lithium permselective ion exchange membranes were prepared on a microporous alumina substrate by dip-coating solution containing Si(OC2H5)(4), LiOC2H5, Mn(OC2H5)(2) and C2H5OH. The membranes showed ion-selectivity for cation over anion and permselectivity for Li+ over Na+. The static transport number for cation [K+] is 0.75 and the permselectivity for Na+ over Li+ is 0.29, comparing 2.57 for ordinary organic ion exchange membrane.
