In this manuscript is reported an investigation on lithium-ion battery composite anodes based on nanotube titanium oxide active material obtained from electrochemical oxidation of titanium metal substrates. Nanotube TiO2 showed a good nominal capacity, particularly taking into account that no electronic conductive additive as well as no binder was incorporated into the TiO2 material. The performance of nanotube titanium oxide anode tapes was compared with that of electrodes based on TiO2 both commercially available and obtained from laser pyrolysis. Cycling tests have indicated that the anodes based on electrosynthesized nanotube TiO2 exhibit the best performance in terms of capacity values and rate capability in combination with very good capacity retention and coulombic efficiency leveling 100% even at high rates. © 2013 Elsevier B.V.
