Films of sintered anatase nanoparticles are promising electrode materials for solar cells, electrochromics, and lithium batteries. For the last application, the anatase phase is essential, since the Li{sup +} insertion into other TiO{sub 2} polymorphs (rutile, brookite) is mostly considered to be negligible. Ten different nanotextured TiO{sub 2} films were prepared from six commercial and four laboratory synthesized precursors. Krypton adsorption isotherms on the films and apparent powders indicate the effect of sintering and agglomeration. Electrochemical characterization of the films was aimed at double-layer charging and Li{sup +} insertion. The relations between the film`s morphology, adsorption properties, and electrochemical behavior in the accumulation regime are discussed.
