Cover Feature: Na0.67Mn(1-x)FexO2 Compounds as High-Capacity Cathode Materials for Rechargeable Sodium-Ion Batteries (ChemElectroChem 3/2021)

The Cover Feature illustrates the use of an iron-substituted Na0.67MnO2 layered transition metal oxide as a high-capacity, low-cost cathode material for next-generation sodium-ion batteries. The excellent cathode performance is correlated with an initial electrochemical activation process. More information can be found in the Article by D. P. Siriwardena et al.
