We investigate the fabrication of an alternative electrode for lithium-ion batteries. The active material consists of self-organized TiO(2) nanotube layers prepared by a simple anodization process. The performances of this type of nanostructured electrode are studied by the combination of structural techniques (Scanning electron microscopy and X-ray diffraction) and electrochemical tests. The discharge/charge properties and cycling performance characteristics are studied for both amorphous and crystalline titania nanotubes. With a maximum areal capacity of 77 mu A h cm(-2), a good capacity retention up to 90% over 50 cycles, nanotubular TiO(2) is a promising electrode for rechargeable Li-ion microbatteries.
