Synergistic Bulk and Interface Modification via Lanthanization Enhances Structural Stability and Ion Kinetics in O3-NaNi1/3Fe1/3Mn1/3O2 Cathodes

Key Points

• The aim is to improve the structural stability and ion kinetics of O3-type NaNi1/3Fe1/3Mn1/3O2 cathodes using lanthanization.
• Applied lanthanization to modify the bulk and interface of the cathode material.
• Analyzed structural changes and ionic transport properties post-modification.
• Conducted performance tests comparing modified and unmodified cathodes.
• The lanthanization process significantly enhanced the structural integrity of the cathodes.
• Improved ion kinetics were observed, leading to better battery performance.
• Modified cathodes showed enhanced energy density compared to their unmodified counterparts.
