Structure and electrochemical behaviour of composite Pb-nano ZnO in sulfuric acid solution for different temperature

Lead is one of the important materials used as an electrode for batter application. With a good performance at the lowest price possible, using lead as an active material for lead-acid battery still high even though the fact that lead waste is very dangerous for the environment. Lead must be optimized to reduce lead waste with adding new material to the lead for the electrode. For this research lead and nano zinc oxide became a composite Pb-Nano ZnO and this composite tested into sulfuric acid solution with various solution temperature 10°C, 25°C, and 40°C. The structure and electrochemical behaviour were analysed with X-Ray Diffraction (XRD) and Potentiostat (LSV and CV) respectively. Detected phase from the spectrum shows lead phase with cubic FCC crystal structure. Linear Sweep Voltammetry and Cyclic Voltammetry test used to see is the composite can be used as an electrode for a battery and is the performance different than lead electrode. The result shows that the composite is electrochemically reversible and corrosion rate decrease when nano ZnO added with lowest corrosion rate 0.011852 mm/year in ZnO 20% wt composition on temperature variation 10°C.
