Abstract

NaHPO-MnO-PbO-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 NaHPO-MnO-PbO-Pb materials were investigated through measurements of cyclic voltammetry. Analysis of the results indicates that doping with a suitable content of MnO and NaHPO removes hydrogen evolution reactions and produces a partial desulphatization of the anodic and cathodic plates of the spent lead acid battery.

摘要

采用红外（IR）、紫外可见（UV - Vis）和电子顺磁共振（EPR）光谱对NaHPO - MnO - PbO - Pb微晶玻璃进行了研究，以了解其结构改性情况，作为电极材料的潜在候选物。通过循环伏安法测量研究了NaHPO - MnO - PbO - Pb材料的电化学性能。结果分析表明，掺杂适量的MnO和NaHPO可消除析氢反应，并使废铅酸电池的阳极和阴极板发生部分脱硫。
