Preparation of Sodium-Ion Cathode Materials with Excellent Performance Using a Co3O4-Modified Conformation Strategy

Using Co 3 O 4 modification of O3-NaNi 0.4 Fe 0.2 Mn 0.4 O 2 to design a sodium-ion layered oxide cathode. The reinforced transition metal layer creates larger space for sodium-ion accommodation and slows the phase transition process.
