[en] Rechargeable oxide batteries (ROB) comprise a regenerative solid oxide cell (rSOC) and a storage medium for oxygen ions. A sealed ROB avoids pumping loss, heat loss, and gas purity
expenses in comparison with conventional rSOC. However, the iron oxide base storage medium degrades during charging– discharging cycles. In comparison, CaFe3O5 has improved
cyclability and a high reversible oxygen storage capacity of 22.3 mol%. In this study, we analyzed the redox mechanism of this compound. After a solid-state synthesis of CaFe3O5, we
verified the phase composition and studied the redox reaction by means of X-ray diffraction, Mossbauer spectrometry, and scanning electron microscopy. Results show a great potential
to operate the battery with this storage material during multiple charging–discharging cycles.
