Fabrication of Fe-Metal Organic Framework-derived Fe2O3 Nanoparticle Li-ion Battery

We, for the first time, fabricated an additive-free battery electrode composed of Fe-zeolitic imidazolate frameworks-derived Fe2O3 nanoparticles (NPs) incorporated in carbon shells (Fe2O3@C) through electrophoretic deposition (EPD). High specific capacity of Fe2O3@C without additives comparable to that of the theoretical capacity (1007 mAh/g) suggests that the electrochemical conversion reactions accompanied by lithiation and delithiation process are not significantly limited by the absence of the conductive agents and binders. The additive-free system paves the way for an efficient experimental probe to investigate the intrinsic electrochemical properties of the metal-organic framework-derived nanostructures.
