AB Previous studies have demonstrated the potential long-term cyclability and stability of TNOs as electrodes in LIBs. However, the wide variety of stoichiometries of TNOs has complicated the study of the physicochemical properties of this material, which can change greatly between different phases, compositions and structures. In this study, two TNO compositions (TiNb2O7 and Ti2Nb10O29) have been synthesized via solid-state and hydrothermal synthesis. A detailed electrochemical characterization as electrodes for LIBs has been performed. Acapacity of 257.3 mA h g 1 has been obtained with losses <6 % after 300 cycles at 1C for the hydrothermal route of the Ti2Nb10O29 composition. Additionally, a complete recovery of capacity was observed after cycling at higher velocities (5C, 10C).
