Electromagnetic Separation

What is the best way to remove metal contaminations from battery raw materials?

Electromagnetic Separator

As a certified global distributor of Nippon Magnetics Inc., a global leader in manufacturing magnetic separators, we bring extensive experience to the international delivery of this equipment. Our expertise primarily lies in cathode and anode active material production for lithium-ion batteries, providing us with insights into the latest trends in battery raw material production. The machine featured here is primarily utilized for active material production and is not commonly employed in battery recycling (yet!).

Clients who have installed or are considering the installation of this machine in their main production lines understand the critical importance of eliminating metal contaminations from battery raw materials. We have observed that customers who neglect the removal of metal contaminations often find themselves at a disadvantage in the highly competitive battery material market.

Of course, the necessity depends on the type of battery material being produced. However, if your production line lacks processes for removing metal contaminations, now might be the opportune moment to consider acquiring and enhancing your raw material quality.

Metal contaminations can detrimentally impact battery performance and efficiency. Metallic impurities can disrupt chemical reactions within the battery, resulting in reduced capacity, diminished energy output, and a shorter lifespan.

Furthermore, metal contaminations pose significant safety risks. Metallic impurities can induce internal short circuits, leading to thermal runaway, overheating, and potentially causing battery fires or explosions, as witnessed in accidents over the past few years. The removal of these contaminants minimizes the likelihood of such hazardous incidents, thereby enhancing the safety of battery operation.

Electromagnectic Features:

  • - Able to remove stainless steel particles.
  • - From R&D scale to mass production scale available.
  • - Several types of magnetic screens available depending on customer requirement.
  • - Magnetic force up to 19,000 GAUSS.

Due to the significantly high magnetic force, we can even eliminate stainless steel particles from your raw materials,
potentially arising from the abrasion of other equipment.
We also understand materials prohibited for battery material application and we have a specific design for it.

Our experiences

  • - Cathode active materials: NCM, NCA, LFP, LCO etc.
    - Anode active materials: Silicon based anode, graphites (synthetic/natural), carbon based anode etc.
    - Precursors, raw materials (lithiums)
  • - Carbon additives
  • - Slurry of active materials

We strongly recommend implementing a process to eliminate metal contaminations in your production line.
We usually offer a test in Japan where customers can assess the processing of their raw materials and observe the removal of metal contaminations by a test machine.
