Restraining O–O Dimerization for Highly Reversible Oxygen Redox in a Sodium-Ion Layered-Oxide Cathode

Kai Zhang, Zhenming Xu, Zhenhua Chen, Fei Wang et al.

Short summary

A novel sodium-ion layered-oxide cathode (Na0.67Fe0.3Sc0.1Mn0.6O2) achieves highly reversible oxygen redox by inhibiting O–O dimerization via a π-type conjugated ring structure, delivering 192.3 mAh g–1 capacity with 80.5% retention after 200 cycles.
