Abstract: This disclosure belongs to the field of battery recycling technologies, and specifically, to a battery recycling method. An example battery recycling method is disclosed including: performing split processing on a battery to obtain a metal shell and an electrode assembly, where the electrode assembly includes a roll core or a lamination; and recycling the metal shell. According to the recycling method in various embodiments of this disclosure, the battery is not wholly crushed, but the battery is split to obtain the metal shell and the electrode assembly. In other words, the metal shell obtained through recycling by using the recycling method in this disclosure is not crushed, thereby ensuring reusability of the metal shell.
