Copper is a crucial component in lithium-ion batteries, mainly used as a material for the anode current collector. Copper is used for the anode current collector foils in batteries due to its excellent electrical conductivity, which enables efficient electron transfer, thus improving overall efficiency.
In addition, copper offers good mechanical strength, maintaining the integrity of the foils during charge and discharge cycles. Its electrochemical compatibility with anodic materials such as graphite prevents unwanted reactions, contributing to battery stability and safety.
Black mass is a term used in the context of lithium battery recycling to refer to the residual material that remains after the battery's external components, such as the casing and current collectors (typically made of copper and aluminium), have been removed. This material is a fine, powdery mixture of various chemical compounds and metals. The composition of black mass can vary depending on the type of battery and its state of wear, but it generally contains: Lithium, Cobalt, Nickel, Manganese, Graphite.
Aluminium is an important component in lithium-ion batteries, mainly used for cathode current collector foils in batteries due to its light weight, corrosion resistance and adequate electrical conductivity, despite being inferior to copper. These characteristics contribute to the battery's durability, stability and overall weight reduction, which are essential for applications such as electric vehicles and portable devices.
Plastics are used in batteries as an insulating material to prevent short circuits, as a porous separator between anode and cathode to prevent direct contact, and as a coating to protect against external agents. It is also used to create modular structures that hold cells in place and for connectors and auxiliary components, contributing to the safety and integrity of the battery.
Stokkermill's lithium battery recycling line makes it possible to recover materials of high commercial value such as aluminium, copper, plastic and black mass from spent lithium batteries.
Our system is equipped with advanced technologies for the efficient and safe separation of these components, minimising environmental and operator risks. All operations take place in isolated environments, connected to filtration systems, to prevent the dispersion of potentially hazardous substances.
The line is capable of processing up to 1,000 kg/h of lithium batteries, ensuring a safe and efficient recycling process.
