Black powder, also called black mass, is one of the most important outputs in lithium battery recycling. It is the powder-rich fraction formed from positive and negative electrode materials after crushing, скрынінг, and separation.

Аднак, a mechanical battery recycling line typically concentrates these materials into black powder rather than producing refined metal salts directly. Further chemical or metallurgical treatment is usually needed if customers want to recover higher-purity lithium, кобальт, нікель, or manganese compounds.

Copper mainly comes from current collector materials and related conductive structures inside lithium batteries. After suitable crushing and separation, it can appear as copper granules or copper-rich fractions.

Copper has a well-established recycled metal market, which means it can support the commercial value of a waste lithium battery recycling project. If copper is mixed too heavily with aluminum, plastics, or powder residues, its selling value and downstream handling may be affected. Таму, physical separation accuracy remains important.

Aluminum is another significant material among the materials from recycled batteries. It may come from battery components such as aluminum foil or shell-related fractions, depending on the battery type.

Recovered aluminum granules can enter recycled metal channels after suitable classification. Although many investors focus first on black mass, stable aluminum separation also helps improve overall resource utilization and reduces the amount of low-value mixed residue.

Iron strips or ferrous fractions are usually not the main profit source, but they remain recyclable. Separating them reduces contamination in other material streams and supports a cleaner overall output structure.

For a practical lithium battery recycling plant, the more clearly each material stream is separated, the easier it becomes to organize storage, sale, or further treatment.
