Abstract
A vacuum cracking method and a cracking apparatus for a power battery are disclosed. The vacuum cracking method includes the following steps that: waste power batteries are fed from a feed hopper and then enter a rolling unit for rolling treatment to obtain a crushed material; the crushed material is transported to a cracking unit for preheating, then heated and cracked under an inert atmosphere or vacuum to obtain cracked gas, solid cracked products and non-crackable products; and the solid cracked products and the non-crackable products are transported to a pyrolysis unit for pyrolysis at an aerobic atmosphere to obtain pyrolysis gas and non-pyrolysis products.
