Abstract	本发明公开了一种回收废旧三元锂离子电池中有价金属的方法。所述方法，包括以下步骤：混合过氧酸与正极废料，经浸出反应，得到浸出液；回收浸出液中的有价金属；所述过氧酸为含有过氧基(‑O‑O)和羧基(‑COOH)的过氧酸。所述方法仅利用过氧酸一种试剂即可实现正极废料中多种有价金属的同时回收，并且提取效率高，浸出时间短。
Other Abstract	The invention discloses a method for recycling valuable metals in waste ternary lithium ion batteries. The method comprises the following steps: mixing peroxy acid and positive electrode waste, and carrying out a leaching reaction to obtain a leaching solution; valuable metals in the leachate are recovered; the peroxy acid is a peroxy acid containing a peroxy group (-O-O) and a carboxyl group (-COOH). According to the method, multiple valuable metals in the positive electrode waste can be recovered at the same time only by using one reagent of peroxy acid, the extraction efficiency is high, and the leaching time is short.
