Policies and ethics Crushing is a substantial process step for the following separation, as it transfers the battery cells or modules to a storable and conveyable bulk material. Crushing also leads to the opening of the battery cells and release of valuable materials.
Previous studies have been conducted using shredders or hammer crushers to crush waste lithium batteries, but it was found that the use of mechanical crushing would lead to low efficiency of the subsequent separation and extraction of metals and high energy consumption.
In the case of crushing, the tools cause an external or internal short due to electrically conductive materials or contact of the electrodes. Discharging and short circuiting of the battery systems before disassembly and short circuiting of every module before crushing eliminates the stored energy and avoids joule heating.
Discharging and short circuiting of the battery systems before disassembly and short circuiting of every module before crushing eliminates the stored energy and avoids joule heating. The interaction of joule heating and chemical reactions can be observed in the crushing product.
Crushing of such battery cells with a capacity of 25 Ah leads to higher concentrations of the organic solvents in the atmosphere of the inner space of a technical scale crusher (Fig. 7.5). For the used crusher and battery type, the lower explosion limit of DMC is reached for a cell mass of three kilograms.
