LiCoO2进行共研磨与PVC使用行星球trill形成钴和锂氯化物的产品机械化学。随后，将研磨的产物分散在水中以提取氯化物。随着研磨的进行，研磨促进了机械化学（MC）反应，并且Co和Li的萃取产率提高。30分钟的研磨使我们能够达到超过90%的钴和近100%的锂。因此，PVC样品中约90%的氯已转化为无机氯化物。这将是一种有效的方法，回收钴和锂的锂离子二次电池（LIS）废物。(C)2004 Elsevier B.V.保留所有权利。
LiCoO2 was subjected to co-grinding with PVC using a planetary ball trill to form Co- and Li-chlorides mechanochemically in the product. Subsequently, the ground product was dispersed in water to extract the chlorides. The grinding facilitate, mechanochemical (MC) reaction, and the extraction yields of both Co and Li are improved as the grinding progresses. The 30-min grinding enables us to reach over 90% for Co and nearly 100% for Li. Accordingly, about 90% of chlorine in the PVC sample has been transformed into the inorganic chlorides by the time. This would be an effective method for recovering Co and Li from lithium-ion secondary (LIS) battery wastes. (C) 2004 Elsevier B.V. All rights reserved.
