The research aims to improve the sodium storage capacity and performance of TiO2 in sodium-ion batteries.
Constructed a sulfur-doped amorphous surface layer on TiO2
Analyzed conductivity and ion diffusion properties
Compared performance of sulfur-modified and unmodified TiO2
The sulfur-doped TiO2 showed improved conductivity
Ion diffusion rates increased significantly
Enhanced sodium storage capacity was observed in the modified TiO2
Abstract
The poor conductivity and slow ion diffusion of anatase TiO2 hinder its application in sodium-ion batteries. To overcome this, we construct a sulfur-doped amorphous surface layer (~1 nm) on TiO2...
