摘要：本文在现有的废铅酸电池的柠橡酸-柠橡酸钠湿法浸取回收错工艺的基础上开发出草酸-草酸钠浸取工艺，比较两种浸取工艺回收制得铬粉的电化学性能。结果表明：利用草酸一草酸钠漫取工艺回收的铅粉制作的电池首次放电容量较柠檬酸-柠檬酸钠工艺提高了10%左右；循环性能明显改善，50次循环后的容量保持率仍能达到85%以上。

Abstract: The paper developed a new oxalate-sodium oxalate wet leaching process on the basic of current citrate-sodium citrate wet leaching process for recovering lead from used lead-acid batteries and compared the electrochemical performances of prepared leady oxide from the two processes. The results showed that compared to the leady oxide from citrate-sodium citrate wet leaching process, the discharge capacity of the lead-acid battery prepared with leady oxide recovered from oxalate-sodium oxalate wet leaching process was increased by 1o %, and its capacity retention rate was maintained above 85%after 50 cycles.
Key words: used lead-acid battery; oxalate-sodium oxalate; citrate-sodium citrate; wet leaching: hydrometallurgy; lead recovery; leady oxide; cycle performance

我国每年大约有五六百万只废铅酸电池产生，含铅金属量约为三四十万吨。预计2013～2014年我国金属铅消耗量可达500万吨，而其中大部分将用于铅酸电池的生产，如此巨大的消耗会使铅
