Heterojunction TiO2@TiOF2 nanosheets as superior anode materials for sodium-ion batteries

Shoujie Guan et al.

Summary: Anatase TiO2 is a promising anode material for sodium-ion batteries, but its shortcomings in semiconductor properties and sluggish Na+ diffusion kinetics hinder further development. A heterojunction TiO2@TiOF2 structure constructed with two-dimensional nanosheets shows stable cycling performance for up to 10,000 cycles at high current densities, attributed to its unique structure and the in situ formation of a NaF protective layer. Density functional theory calculations indicate that the heterostructure TiO2@TiOF2 nanosheets exhibit improved electrical conductivity and lower formation energies of Na+ ions compared to the separated TiO2 and TiOF2.
