A fundamental study of deep eutectic solvents and their application to green battery recycling processes

该项目的目的是开发一种更安全和更便宜的替代方法，以取代目前用于回收铅酸电池的火法冶金处理方法。这将通过开发基于溶剂的低温工艺来完成。该工艺将使用低成本、可持续和可生物降解的溶剂来溶解废电池流中发现的各种铅化合物。溶解的铅可以通过化学或电化学的方法以铅的氧化物或金属的形式回收，这两种物质都是制造新电池的有用材料。这项技术可以很好地取代非正规电池回收商使用的简易熔炉，这些熔炉在发展中国家构成严重的污染危害。

The aim of this project is to develop a safer and cheaper alternative to the current pyrometallurgical processing method applied to the recycling of lead acid batteries. This will be done by developing a solvent based, low temperature process. The process will use low cost, sustainable and biodegradable solvents to dissolve a variety of lead compounds found in waste battery streams. Dissolved lead can then be recovered chemically or electrochemically as lead oxide or metal, both of which are useful materials for the manufacture of new batteries. This technology could be well positioned to replace the improvised furnaces used by informal battery recyclers that pose a significant pollution hazard in developing countries.
