Abstract

NaH₂PO₄-MnO₂-PbO₂-Pb vitroceramics were studied usinginfrared (IR), ultraviolet-visible (UV-Vis) and electron paramagnetic resonance (EPR) spectroscopies to understand the structural modifications as potential candidates for electrode materials. The electrochemical performances of the NaH₂PO₄-MnO₂-PbO₂-Pb materials were investigated through measurements of cyclic voltammetry. Analysis of the results indicates that doping with a suitable content of MnO₂ and NaH₂PO₄ removes hydrogen evolution reactions and produces a partial desulphatization of the anodic and cathodic plates of the spent lead acid battery.

Keywords: NaH2PO4-MnO2-PbO2-Pb vitroceramics; car battery; electrode; recycling; structure.
