文章摘要：PbO₂和PbSO₂的混合物在用碳酸盐脱硫后，在密闭容器中140 ^oC甲醇中处理可以得到PbO·PbCO₃和 PbCO₃。后者经450 ^oC灼烧可以得到高活性的PbO。其电化学性能超过现有工业上用金属铅制备的含铅氧化铅，可用于生产铅酸电池。

论文的英文摘要如下：

We have developed a novel route to make new batteries from spent ones, in which we obtain and regenerate the active materials of positive electrode and negative electrode respectively. For the spent lead acid batteries, the positive electrode active materials contain both PbSO₄ and PbO₂. To make full use of them, we have to investigate the treatment of the mixtures rather than only PbO₂, which we have reported previously. Here we report our investigation on three mixtures of PbSO₄ and PbO₂ in different mole ratios, as well as the electrode materials directly from the spent batteries. The mixtures are firstly desulphated, and then solvothermally processed in methanol at 140 °C for 24 h. The as-obtained solids contain both PbO·PbCO₃ and PbCO₃, which have been calcined to form α-PbO. The α-PbO powders are similar irregular particles and highly electrochemically active, which discharge  around 170 mAh g⁻¹ at 5 mA g⁻¹, 80 mAh g⁻¹ at 200 mA g⁻¹ and 60 mAh g⁻¹ at 400 mA g⁻¹ with excellent cyclic stability in 50 cycles.
