Exploring the potential of combining over- and under-stoichiometric MIEC materials for Oxygen-Ion Batteries
The increasing demand for energy storage solutions has spurred intensive
research into next-generation battery technologies. Oxygen-ion batteries
(OIBs), which leverage mixed ionic-electronic conducting (MIEC) oxides, have
emerged as promising candidates due to their solid, non-flammable nature and
potential for high power densities. This study investigates the use of
over-stoichiometric La2NiO4+delta (L2NO4) as a cathode material for OIBs,
exploring its capacity for electrochemical energy storage. Half-cell
measurements reveal that L2NO4 with a closed-pore microstructure can store
oxygen, achieving a volumetric charge of 63 mA.h.cm-3 at 400 {\deg}C with a
current density of 3.6 uA.cm-2 and potentials up to 0.75 V vs. 1 bar O2.
Additionally, a functional full cell combining over-stoichiometric L2NO4 and
under-stoichiometric La0.5Sr0.5Cr0.2Mn0.8O3-delta (LSCrMn) has been
successfully developed, demonstrating excellent cyclability and coulomb
efficiency. The full cell reaches a maximum volumetric charge of 90 mA.h.cm-3
at 400 {\deg}C, 17.8 uA.cm-2, and a cut-off voltage of 1.8 V. This proof of
concept underscores the viability of combining over- and under-stoichiometric
MIEC materials in OIBs and provides critical insights into optimizing electrode
materials and tuning oxygen content for improved performance. This research
lays the groundwork for future advancements in OIB technology, aiming to
develop materials with lower resistance and higher efficiency.
