Abstrakt: A novel 4 × 4 Wadsley-Roth block phase, Nb 9 Ti 1.5 W 1.5 O 30 , 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 .
