Abstract

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+).
