Metal recyclability from secondary sources is vital in the context of circular economy. Vanadium (V) is one such critical metal due to its increasing demand in various industries. Herein, a series of NO 3 – intercalated Lanthanum (La)-doped Mg–Al layered double hydroxides (LDHs) were synthesized to remove V oxyanions from alkaline solution.

While all batteries experience electrolyte degradation, flow batteries in particular suffer from a relatively faster form of degradation called "crossover." The membrane is designed to allow small supporting ions to pass through and block the larger active species, but in reality, it isn''t perfectly selective.
