Lead-acid batteries are a reliable and cost-effective uninterrupted power supply for cars, wheelchairs, and others. Recycling the spent lead-acid batteries has increased cost and could be a serious pollution issue after extensive use. It is important to exploit new-generation application to increase their value. In this article, we used a simple method for recycling spent lead-acid batteries for a useful lead iodide resource with a high purity of over 99% and a recycling yield of 93.1% and then fabricated multifunctional FAPbI3 perovskite diodes using recycled lead iodide (PbI2). The cost of recycled PbI2 based on lab-grade chemicals is estimated to be only 13.6% that of lab-grade PbI2, which undoubtedly greatly reduces the preparation cost of devices in the lab. The external quantum efficiencies of our perovskite diodes prepared with commercial and recycled PbI2 are 19.0 and 18.7%, respectively, which shows that the performance of the device prepared from recycled PbI2 is comparable to that of commercial lab-grade PbI2. Based on the expense of industrial-grade chemicals, the cost of recycled PbI2 is extrapolated to be 70.2% that of industrial-grade PbI2. Therefore, it can not only offer an approach to recycle hazardous solid waste but also save manufacturing cost of new-generation photoelectric devices, leading to earning additional value for lead waste.

回收废铅酸电池成卤化铅资源净化和多功能钙钛矿二极管
铅酸电池是一种可靠且具有成本效益的不间断电源，适用于汽车、轮椅等。回收废铅酸电池会增加成本，并且在大量使用后可能会造成严重的污染问题。开发新一代应用程序以增加其价值很重要。在本文中，我们使用一种简单的方法回收废铅酸电池，将其作为有用的碘化铅资源，纯度超过 99%，回收率达 93.1%，然后使用回收的碘化铅制造多功能 FAPbI 3钙钛矿二极管（ PbI 2 )。基于实验室级化学品的回收 PbI 2的成本估计仅为实验室级 PbI 2 的13.6%，无疑大大降低了实验室器件的制备成本。我们用商业和回收 PbI 2制备的钙钛矿二极管的外量子效率分别为 19.0% 和 18.7%，这表明由回收 PbI 2制备的器件的性能与商业实验室级 PbI 2相当。根据工业级化学品的费用，回收 PbI 2的成本推断为工业级 PbI 2 的70.2% 。因此，它不仅可以提供一种回收有害固体废物的方法，还可以节省新一代光电器件的制造成本，从而为铅废物创造附加价值。
