"Doping with W<sup>6+</sup> ions enhances the performance of TiNb2O7 as" by Yu Sheng Hsiao, Cai Wan Chang-Jian et al.
Monoclinic TiNb2O7 (TNO) has recently been reported as a promising anode candidate for next-generation high-energy–density lithium-ion batteries (LIBs). Unfortunately, poor electronic and ionic conductivities have limited its practical application. In this study, we prepared selectively W6+-doped TNO to overcome these drawbacks. We demonstrate herein the effect of site-selective substitution on the electrochemical performance of TNO after selectively doping its Ti4+ and Nb5+ sites with W6+ ions. The W6+ ions were incorporated into the TNO lattice without dramatically altering the lattice par...
