Lithium-Ion batteries –
Recycle and reuse
Primobius enables its customers to recover key materials from lithium-ion batteries in an environmentally friendly and sustainable manner. The goal is to obtain valuable metals for reuse in manufacturing battery cathodes. Lithium-ion batteries consist of an anode, cathode, separator, electrolyte, and current collectors, all enclosed within a casing. These batteries come in various formats and chemistries, each requiring tailored recycling approaches.
Primobius provides advanced solutions that facilitate the efficient recovery of these materials, reducing reliance on mining and primary material production.
Stage 1: Shredding and beneficiation
The shredding and beneficiation stage focuses on separating and recovering materials with precision and efficiency. The patented wet shredding process ensures safe handling by minimizing dust and heat generation, while enabling the clean separation of components for further processing.
Materials recovered through shredding and beneficiation:
Plastic (PE, PP)
The microporous plastic separator materials are commonly made from polyethylene (PE) and polypropylene (PP), which are readily recycled. These plastics are recovered and supplied to plastics recycling companies.

Steel
The high-value steel casing materials that maintain the structural integrity of the batteries and afford chemical resistance and corrosion protection are recovered and supplied to metals recycling companies.

Copper and aluminium foil
The anode current collectors have a substrate of copper and aluminium foil are also recovered and supplied to metals recycling companies.

Black mass
The black mass contains the active materials for the operation of batteries. During a following processes, it is possible to extract from these active materials lithium, nickel and cobalt in a suitable form for reuse in making battery cathode materials.

Stage 2: Hydrometallurgical refining
The Primobius hydrometallurgical plant builds on the results of the first stage by refining black mass to recover high-value metals such as lithium, cobalt, and nickel. This method achieves excellent recovery rates while maintaining energy efficiency, ensuring that the extracted materials can be reused in critical applications like battery manufacturing.
Primobius processes lithium-ion batteries with cathode chemistries such as lithium cobalt oxide (LCO), lithium nickel cobalt manganese oxide (NCM), and lithium nickel cobalt aluminium oxide (NCA). Recovered metals are supplied as high-purity crystalline chemicals back into the LIB supply chain. Additionally, valuable sulphate products such as manganese sulphate, copper sulphate, and ammonium sulphate are obtained, which are suitable for industrial and agricultural applications.
Materials recovered through hydrometallurgical processing:
Cobalt sulphate – battery grade
It is suitable as a raw material for precursor cathode active materials used in the manufacture of lithium-ion batteries.

Nickel sulphate – battery grade
Is a high purity crystalline nickel sulphate hexahydrate with very low levels of impurities.

Ammonium sulphate
Ammonium sulphate is commonly used as a fertilizer or in blends where it contributes the key nutrients, nitrogen and sulphur.

Manganese sulphate solution
Manganese sulphate is used as a fertilizer and as a livestock supplement where soils are manganese deficient.

Lithium sulphate solution
Lithium sulphate solution is a precursor material for lithium hydroxide monohydrate, a raw material used in the manufacture of lithium-ion-batteries.

Copper sulphate
Copper sulphate is commonly used as a fungicide, algicide and herbicide.

Graphite
The graphite anodes are recovered in the form of a graphitic residue that can be further processed to yield high quality graphite and potentially reused in lithium-ion battery anodes.
