Description	Phase-pure TiO2(B) with microfibrous morphology was prepared via a newly developed method from amorphous TiO2. Cyclic voltammetry evidences that Li-insertion into TiO2(B) is governed by a pseudocapacitive faradaic process, whose rate is not limited by solid-state diffusion of Li+ in a broad interval of scan rates. This unusual behavior was discussed in terms of the crystal structure of the TiO2(B) host, having freely accessible parallel channels for Li+-transport perpendicular to the (010) face. The characteristic Li-insertion electrochemistry of TiO2(B) allows re-interpretation of several previous reports, which did not consider explicitly this relation or the presence of TiO2(B) in various TiO2 materials of different origin.

(en) Byl vyvinut nový syntézní postup pro přípravu fázově čistého TiO2(B) s vláknitou morfologií. Cyklická voltametrie ukázala, že inserce lithia do uvedeného materiálu probíhá jako pseudokapacitní faradaický process, jehož rychlost není limitována difúzí Li dovnitř tuhé fáze pro široký interval rychlostí skenu.
