Mixed‐Valence Li/Fe‐Based Metal–Organic Frameworks with Both Reversible Redox and Sorption Properties

There's more to LiFe: When used as an electrode in a lithium half cell, the metal–organic framework LixFeIIxFeIII1−x (OH) 0. 8F0. 2L (L=O2CC6H4CO2) shows a reversible redox process around 3. 0 V versus Li+/Li0 with interesting capacity retention and rate capability (see voltage profile for a LixFe (OH) 0. 8F0. 2L half cell; inset: representation of lithium insertion upon oxidation to Li+).
