When recycling lithium-ion batteries, the drying phase is crucial for removing the electrolyte from the crushed battery. The electrolyte is then condensed and cleaned. Which vacuum pumps are suitable for these process steps?

When recycling lithium-ion batteries, the drying phase often follows the discharging and shredding. This is crucial for removing the electrolyte. During vacuum drying, the boiling point of volatile components is lowered so that they can evaporate at lower temperatures. The achievable base pressure of a vacuum system is generally limited by the pumping principle of the technology used. In order to achieve a higher vacuum level—especially for removing solvents with low vapor pressure—different vacuum technologies often have to be combined, as individual vacuum pumps usually lose suction power near their final pressure. Depending on which pump types are used, there are various advantages and disadvantages.
