Materials in the Na-rich antiperovskite family are promising candidates as solid electrolytes (SEs) for all-solid-state Na-ion batteries (NIBs). In this work, we carry out ab-initio calculations to study various properties of Na3OClNa3OCl, namely the formation energies of various neutral defect pairs, the defect hopping barriers, the solution energies of high valence alkali earth metal substitutes to the Na atoms, and the effect of such substitution to the Na migration. While the introduction of alkali earth metal ions increases the Na vacancy concentration, the activation energy of Na transport also increases. Furthermore, we identify Ca as the most promising alkali earth metal to be doped into Na3OClNa3OCl due to its low binding energy and relatively small impact on the migration barrier. Our work provides a theoretical framework for further improving the Na conductivity of materials in the antiperovskite family for all-solid-state NIBs.

This article presents a facile and effective approach to activate the bifunctionality of calcium-manganese perovskites towards oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). We substituted Nb into the Mn site of CaMnO3 (CMO) and treated the material with H2. The as-obtained CaMn0.75Nb0.25O3-δ (H2-CMNO) displays the same structure as CMO and, compared to CMO, H2-CMNO exhibits significantly improved OER performance, including a lower overpotential, a reduced Tafel slope, a higher specific activity, and enhanced stability. In addition, the ORR performance of H2-CMNO is also greatly enhanced, relative to CMO, with a higher ORR activity and a more efficient electron-transfer pathway. H2-CMNO shows even higher activity-per-catalyst-cost and superior stability than state-of-the-art materials such as IrO2 and Pt/C. This great enhancement in ORR and OER activity of H2-CMNO is attributed to several factors including phase stabilization, optimized eg filling, better OH- adsorption, and improved electrical conductivity.

The development of non-precious metal-based oxygen evolution reaction (OER) electrocatalysts is one of the keys to lower the cost of various renewable energy technologies including fuel cells, water electrolyzers, and metal-air batteries. Perovskite oxides are among the best catalysts for OER in alkaline solutions. In the perovskite family, La0.8Sr0.2CoO3-δ (LSC) has been reported to have OER catalytic properties dependent on the characteristics of its surface, but where its activity and stability are still not high enough for applications. In order to improve the surface catalysis of LSC, we have subjected it to multiple H2O2 treatments. After 4 treatments, lasting 6 hours each, the current density of LSC at 1.70 V (vs RHE) increased by a factor of 6.6 and concomitantly, the Tafel slope decreased from 105.5 to 76.6 mVdec−1 compared to untreated materials. The long-term stability also improved dramatically after treatment. All these improvements are likely linked to the formation of an amorphous layer of hydrous oxide on the LSC particles during treatment.
