Comparative Geochemistry of Metals ... - Wiley Online Library

The organic-rich (50% organic carbon) kolm of the Upper Cambrian shale is more enriched in uranium (0.5%), radiogenic-lead (200 ppm), yttrium (800 ppm) and heavy rare earth elements (HREE, e.g. ytterbium 45 ppm), but depleted in other elements (molybdenum, vanadium, nickel). This allows the classical VRFB to keep up to approximately 1.8mol/L vanadium in solution and thus achieve maximum energy density of up to approximately 38Wh/L. Vanadium is a relatively frequently occurring metal that is enriched as a by-product during the combustion of fossil fuels. Its main application is as an alloying metal for steel production.
