Oxygen-free closed environment: Vacuum evacuation removes internal air and oxygen, completely cutting off combustion and explosion conditions for flammable battery materials.
Low-temperature impurity separation: Vacuum reduces the boiling point of electrolytes and organic solvents, enabling efficient volatile removal at low temperatures without damaging metal material properties.
Zero-discharge gas recovery: Closed vacuum pipeline collection realizes centralized recovery of electrolytes and VOCs, turning waste into reusable resources.
High-precision purification: Continuous negative pressure degassing and drying eliminate micro-impurities, greatly improving the grade and market value of recycled battery materials.
Vacuum inertization technology evacuates all air inside the sealed shredding chamber first, then fills the cavity with high-purity nitrogen. The entire shredding process is completed in an oxygen-free vacuum inert environment. It completely avoids thermal runaway and deflagration risks, realizing intrinsically safe battery crushing operations. This technology is the mandatory safety process for large-scale automatic battery recycling lines.
Vacuum thermal desorption works under negative low-pressure conditions to vaporize organic solvents and lithium hexafluorophosphate electrolytes at low temperature. The vacuum system extracts all volatile gas, which is condensed and recovered through a professional condenser. This process not only eliminates toxic gas pollution but also realizes electrolyte resource recycling, creating additional economic benefits for factories.
After preliminary screening and crushing, vacuum purification equipment removes residual moisture, trace electrolytes, and organic impurities in black mass. Compared with atmospheric purification, vacuum-processed black mass has higher density, more stable chemical properties, and can be directly used for the production of high-grade new battery cathode materials, greatly improving product added value.

Q1: Why is vacuum inert shredding mandatory for spent battery processing?
A1: Vacuum evacuation removes oxygen in the crushing chamber, forming an inert environment to completely avoid thermal runaway and explosion caused by contact between residual battery active materials and air, realizing safe industrial crushing.
Q2: Can vacuum technology recover waste battery electrolytes?
A2: Yes. Vacuum low-temperature thermal desorption vaporizes residual electrolytes, which are condensed and recycled through vacuum systems, realizing resource reuse and reducing environmental pollution.
Q3: How much can vacuum systems improve battery material recovery rate?
A3: Compared with traditional processes, vacuum closed-loop recycling increases the comprehensive recovery rate of lithium, cobalt, nickel and other precious metals from 75% to more than 90%, greatly reducing resource waste.
Q4: Do battery recycling vacuum pumps need explosion-proof certification?
A4: Absolutely. Battery recycling involves flammable organic volatile gases. All vacuum equipment must pass professional explosion-proof certification to avoid electrical spark-induced safety accidents.
