The client is a company specializing in battery recycling and processing systems. When the used batteries arrive, they are first tested and deeply discharged, then disassembled to the size of battery modules, ground into granular form, dried, and the electrolyte removed. After screening, the valuable lithium, nickel, manganese, cobalt and graphite are extracted for further processing by magnetic separators to sort the materials. The non-magnetic materials are separated, and all the materials are classified into three categories: “black powder”, copper and aluminum, and plastic. The “black powder” will be separated into raw materials and used for the production of new batteries.
