Li + Intercalation into TiO 2 ‐B nanowires is reported up to a composition of Li 0.91 TiO 2 ‐B (specific charge capacity: 305 mA h g –1 ) and with a superior rate capability to nanoparticulate anatase and bulk TiO 2 ‐B (see Figure). The combination of high capacity for Li + intercalation, high rate capability, and a potential of ∼1.6 V, renders the intercalated nanowires interesting as anodes for rechargeable lithium batteries and negative electrodes for supercapacitors.
