However, it's important to mention that prior to subjecting batteries to crushing and other mechanical processes, they must first be deactivated and discharged, as performed in the disassembly and pyrometallurgical phases. Incorrect execution of this step poses a risk of battery explosions or fires. Should the thermal deactivation phase be omitted, pulverization can be conducted under cryogenic conditions or in an inert atmosphere to prevent metal oxidation and combustion. However, this method is considerably costlier .
