The Electrochemical and Structural Changes of Phosphorus-Doped TiO₂ through In Situ Raman and In Situ X-Ray Diffraction Analysis.

ABSTRACT: Doping is a widely employed technique to enhance the functionality of lithium-ion battery materials, tailoring their performance for specific applications. In our study, we employed in situ Raman and in situ X-ray diffraction (XRD) spectroscopic techniques to examine the structural alterations and electrochemical behavior of phosphorus-doped titanium dioxide (TiO₂) nanoparticles. This investigation revealed several notable changes: an increase in structural defects, enhanced ionic and electronic conductivity, and a reduction in crystallite size. These alterations facilitated higher lithiation rates and led to the first observed appearance of LiTiO₂ in the Raman spectra due to anatase lithiation, resulting in a reversible double-phase transition during the charging and
