Abstract:
This research aims to prepare nanostructral lead oxides used as active materials in HEVs, with a green hydrometallurgy recovery method from spent batteries via a homemade low-temperature. The nanostructral products were prepared by lead citrate precursor, which was synthesized through leaching of spent lead acid battery paste in citrate salt aqueous system. The nanostructral products were characterized by X-ray diffraction, scanning electron microscopy and thermo gravimetric-differential thermal analysis. The results show that the product comprise orthorhombic phase B-PbO, metallic Pb and elemental C in N2 atmosphere, while B-PbO with a small part of -PbO and Pb in air atmosphere. The PbO/Pb ratio of product can be controlled by modifying temperature, calcination time and air amount. And the battery testing results show that initial capacity of novel lead oxide is better than traditional oxides, and nanostructural lead oxides could be used as active materials in HEVs.
