How to separate and purify waste lithium battery recycling copper, aluminum and carbon powder?

The negative electrode of waste lithium battery is composed of copper foil and graphite, and the positive electrode is composed of aluminum foil and lithium cobalt oxide powder. For the recycling of waste lithium battery, our factory produces a complete set of lithium battery crusher equipment, which adopts hammer crushing and vibration screening. Separation and purification of waste lithium batteries by combined process with air separation.

Waste lithium-ion batteries usually contain 5% to 15% of cobalt, 2% to 7% of lithium, and 0.5% to 2% of nickel, and their recycling value is relatively high. Lithium-ion batteries also contain toxic substances such as lithium hexafluorophosphate, which will cause serious pollution to the environment and ecosystems. Heavy metals such as cobalt, manganese, and copper will also harm humans themselves through the biological chain through accumulation, which is extremely harmful. With the wider application of lithium-ion batteries, it is of great social and economic significance to recover valuable metals in lithium-ion batteries, reduce environmental pollution, and alleviate resource scarcity.

The waste lithium battery recycling and processing equipment is similar to the physical method. When the mechanical method is used to recover the lithium battery, the lithium battery will be destroyed and selected as a whole at first, and the electrode material powder of the lithium battery will be initially obtained, and then the electrode material powder will be correlated. Heat treatment to remove organic binders on the battery, and then recover the metal ions in the battery by flotation separation.
