Beschreibung
Zusammenfassung:	Provided is a method for recovering lithium, which recovers lithium from a lithium ion secondary battery, and which comprises: a heat treatment step for obtaining a heat-treated product by heat-treating a lithium ion secondary battery that remains a voltage of 80% or more with respect to a rated voltage; a crushing step for crushing the heat-treated product to obtain a crushed product; and a lithium recovery step for recovering lithium from the crushed product. 提供一种锂的回收方法，其为从锂离子二次电池回收锂的锂的回收方法，其包括：热处理工序，通过对相对于额定电压残留80％以上的电压的锂离子二次电池进行热处理，得到热处理物；破碎工序，通过将前述热处理物破碎，得到破碎物；和锂回收工序，从前述破碎物回收锂。
