چکیده
The reversibility of oxygen anion redox is remarkably improved for partially Ti-substituted Na 4/7 [? 1/7 Ti Mn 5/7 ] and operates at a higher potential ( vs. Na/Na + ) compared with the parent material 6/7 ].

متن کاملDissolution and ionization of sodium superoxide in sodium–oxygen batteries
With the demand for high-energy-storage devices, the rechargeable metal-oxygen battery has attracted attention recently. Sodium-oxygen batteries have been regarded as the most promising candidates because of their lower-charge overpotential compared with that of lithium-oxygen system. However, conflicting observations with different discharge products have inhibited the understanding of precise...

DOI: 10.1002/aenm.201500174 The continuous pulverization of alloy anodes during repeated sodiation/desodiation cycles is the major reason for the faster capacity decay. However, if these elements can form a compound (such as Sn 4 P 3 ) after each Na extraction, the pulverization of these elements can be partially repaired and the accumulation of pulverization can be terminated. Therefore, we ca...
