Abstract

Powders of La2O3 were mixed with mechanical ball-milling technique (MA) adding TiO2, to improve the electrochemical performance as a storage material. Microstructures, morphologies and electrochemical results were investigated using TEM, X-ray diffraction (XRD), Cyclic Voltammetry and Potentiodynamic studies. Results showed that, the samples with TiO2 content affected the capacity of response. The alloys exhibit a superior capacity and stability adding TiO2. The milling ball to powder weight ratio was kept 5 to 1 for all experimental runs. Milling intervals were 0, 2 and 4 hrs; using alternate cycles of 30 minutes milling and 30 min resting. The nanostructure TiO2 powder, improves the samples to design a better electrode. TiO2 has significant influence on electrochemical performance of electrodes. Electrochemical experiments were performed on ACM Instruments Gill AC and a typical three electrode setup was constructed to measure the electrochemical properties of the working electrode. Here, platinum was used as the counter electrode and calomel was used as the reference electrode. Structures of the samples were analyzed by digital image tools.
