Fe2O3 Microcubes Derived from Metal–Organic Frameworks for Lithium-Ion Storage with Excellent Performance

Transition metal oxides are regarded as a potential electrode material for lithium-ion storage due to it features high theoretical capacity and low cost. In this study, the possibility of Fe2O3 microcubes an was investigated, where anode were created through Prussian blue (PB) metal–organic frameworks (MOFs) followed by calcination process at temperature. The results showed that obtained 500 °C exhibited superior electrochemical performances than 700 °C. increase in temperature will lead further sintering reaction between particles formation cracks voids crystals eventually breakup microcube so lower stable structure electrode. excellent/stable lithium performance thus is promising LIBs.
