In the last years of research on new anode materials for advanced Lithium-Ion Batteries, niobium-based oxides are raising growing attention due to high theoretical capacities, fast rate capabilities and safety reasons. In this paper, the complex structural and electrochemical features of FeNb_11 O_29 are unravelled with multiple techniques: the symmetrisation of the octahedral framework that occurs after the reduction of Nb5+ cations, detected for the first time, seemsto be the key of the electrochemistry of FeNb_11 O_29 .
