Delia Niculina Piscoiu, Simona Rada, Horatiu Vermesan
TL;DR
This paper explores recycling materials from old car batteries to create new materials with improved electrochemical properties.
Contribution
A novel recycling method using melt quenching to enhance electrochemical performance of vitreous materials from spent batteries.
Findings
Samples with 8 and 10% Fe showed the best electrochemical performance.
The sample with 8% Fe had lower resistance and higher electrical conductivity.
Iron doping reduced sulfate units and introduced Fe3+ ions with varied coordination geometries.
Abstract
This paper presents a novel approach for the recycling of spent anodic plates from lead-acid batteries through the melt quenching method using iron and calcium oxides and iron powder. The resulting recycled samples, with a 3CaO·5Fe2O3·xFe·(92 − x)Pb composition, where x = 0, 1, 3, 5, 8, 10, 15, and 25% mol Fe, were characterized and analyzed in terms of their electrochemical performance. X-ray diffractograms show vitroceramic structures with varied crystalline phases. Analysis of the IR (infrared spectra) data shows a decrease of sulphate units due to doping with iron content. The ultraviolet–visible (UV-Vis) and electron spin resonance (ESR) data reveal the presence of Fe3+ ions with varied coordination geometries. Cyclic and linear sweep voltammograms demonstrate that the samples with 8 and 10% Fe exhibit superior electrochemical performance compared to other vitroceramics. The…
