Electrochemical properties of anodically grown TiO2
MetadataShow full item record
Nanostructured amorphous and anatase TiO2 are both considered as high rate Liinsertion/extraction electrode materials. Here we present the preparation of titania on titanium substrate by the anodic oxidation method. The anodization was conducted using a two-electrode configuration under a constant voltage. Highly viscous fluoride containing glycerol electrolyte was used to anodically grow amorphous TiO2 on titanium substrate. The crystal structure was characterized by X-ray diffraction. After thermal treatment at 400 °C amorphous TiO2 crystallizes to anatase phase. The surface morphology was observed by scanning electron microscopy. Electrochemical properties of the as-prepared substrates directly used as anode in lithium-ion cell were examined through galvanostatic discharge/charge tests.
