Interfacial modulation engineering for sodium layered oxide cathode: air stability, ion-transfer kinetics, and phase evolution

https://www.eurekalert.org/news-releases/1089306

"sodium-ion battery cathode: high capacity, straightforward/ efficient fabrication, but poor air stability, sluggish interfacial kinetics, detrimental phase transitions resulting in unsatisfactory cycling stability/ inferior rate capability... overcome using organic/ inorganic coating, interfacial-coating-doping, heterogeneous phase design, enabling residual alkali in-situ conversion and/ or enhanced interfacial stability, improved electrochemical reaction kinetics, mitigated phase evolutions, layered-tunnel heterostructure building"
