Recycling lithium-ion batteries

Recycling materials from batteries and accumulators

Fossil fuels are being increasingly replaced by other energy sources. Accumulators and batteries are increasingly being produced to store renewable energy. As a result, the need for low-cost recycling methods is also growing. BHS-Sonthofen has developed an efficient and reliable process for recycling accumulators and batteries in a safe and environmentally friendly manner. Using this process, it is also possible to extract raw materials such as copper, lithium, nickel and cobalt for reuse.

Benefits at a glance:

  • High process reliability
  • Maximum yield of raw materials
  • Gas-tight design
  • Models in different sizes available (modular design)

New method of recycling

The shredded batteries are heated in AVA dryers of type HTC-T or HTK-T

New method of recycling

Once the batteries have been discharged, they are shredded using the BHS rotary shear (VR) or universal shredder (NGU). In order to prevent sparks, a customized shredder that has been made gas tight and that operates in a protective atmosphere is used.

Once the feed material has reached the desired target size, the parts fall through appropriately designed grid segments. The shredded batteries are heated in batches in AVA dryers of type HTC-T or HTK-T located directly downstream to evaporate the electrolyte components for subsequent recovery in a condensation unit. Dry mechanical processing is used to render the solid components completely free of electrolytes. Black mass can be recovered as soon as initial screening has been performed. Light and heavy materials are then sifted and separated. The remaining composites are sent for a second phase of shredding and are then fed into a dry mechanical sorting system.

Raw material recycling according to your requirements


Raw material recycling according to your requirements

Our shredding machines are available in different sizes to meet your individual requirements. Our systems allow you to process any type of cell and module. The end products are aluminum, high-grade copper concentrates and pure black mass, which contains lithium salts, manganese, cobalt or nickel depending on the type of battery. All three fractions are immediately ready for remarketing.
