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.
