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.

Implication

An investigation shows enhanced structural stability and ion kinetics in sodium-ion battery cathodes, suggesting new methods for better battery performance.

Abstract

O3-type layered transition metal oxides represent promising cathode materials for sodium-ion batteries (SIBs) due to their high energy density and low cost, yet their practical deployment is limited by sluggish...
