Description

Abstract
The lead acid batteries are ones of the oldest and the most widely used type of battery technologies in the world. They are still used in the automotive industries and energy storage systems. The recycling of spent electrodes of the car battery is of major concern due to the importance of minimizing the negative effect on the environment and the secondary resources obtained from the battery components. The aim of the research proposed in this paper is the preparation of new materials from the spent plates of a decommissioned automotive battery and its doping with copper oxide and antimony trioxide powder. In this paper the structural, optical and electrochemical properties of copper – antimony vitreous materials obtained by melt quenching method using as raw materials spent active mass of lead acid battery, CuO and Sb2O3 powders. The simultaneous adding of Sb2O3 and CuO enhance the mechanical and conductive properties of the recycled material. The characterization of the obtained materials was performed by X - ray diffraction (XRD) and infrared (IR), UV-Vis, photoluminescence (PL) and electron paramagnetic resonance (EPR) spectroscopies. The electrochemical performances of the recycled materials were characterized by cyclic voltammetry (CV) and linear sweep voltammetry (LSV).
