Abstract

A novel 4 × 4 Wadsley-Roth block phase, Nb₉Ti_1.5W_1.5O₃₀, has been prepared and its structure determined through Neutron and X-ray diffraction studies. Electrochemical testing indicated excellent high rate performance, with a returned delithiation capacity of 184 (4) mA h g^-1 at a current of 2 A g^-1.
