Impact of the composition on the electrochemical performance of KyVxTi8-xO16 (0 ¿ x ¿ 2)
This proposal focuses on the determination of the crystal structure and composition of 7 hollandite-type compositions with the general formula KyVxTi8-xO16 (0 ¿ x ¿ 2), which might be employed as electrode materials in rechargeable K-ion batteries. The main goal of this work is to accurately determine the position and occupancy of oxygen and potassium atoms as well as the likely presence of water molecules or other species in the structural tunnels. Furthermore, this neutron diffraction experiment would aid in determining the samples' relative titanium and vanadium contents (by difference) or any possible V-Ti ordering. For these tasks we ask for 1 days at D2B diffractometer
