recycle Lithium ion battery machine

With the popularity of new energy vehicles and electronic devices, the number of waste lithium batteries has increased dramatically. If not handled properly, heavy metals (such as cobalt, nickel, lithium) and electrolytes in them may pollute soil and water sources. Scientific recycling can not only reduce environmental damage, but also extract high-value metals and alleviate resource shortages. Lithium battery recycling equipment is the core technology to achieve this goal.

Current status of waste battery recycling

Millions of tons of waste lithium batteries are produced worldwide every year, but the recycling rate is still less than 20%. The main reasons include:

Imperfect recycling system: Some countries lack standardized recycling channels, and batteries flow to informal dismantling companies.

High technical threshold: Lithium batteries have complex structures, and positive electrode materials, electrolytes, diaphragms, etc. need to be finely processed.

Economic limitations: Metal price fluctuations affect recycling profits, and efficient recycling technology relies on expensive equipment.

Recycling line equipment configuration

A complete lithium battery recycling production line mainly includes:

Discharge and disassembly equipment: Safety is ensured by salt water immersion or low-temperature discharge, and the robotic arm automatically disassembles the shell.

Crushing and sorting system: Use hammer crusher, airflow separator and magnetic separator to separate metals, plastics and diaphragms.

Leaching and extraction equipment: Use acid leaching or bioleaching technology to extract metals such as cobalt, nickel, lithium, etc., and solvent extraction and purification.

Electrolysis and crystallization device: Obtain high-purity metals through electrolysis, or prepare battery-grade raw materials such as lithium carbonate.

Recycling process

Pretreatment: Disassemble the battery pack after discharge and separate the battery cells.

Crushing and sorting: Crush the battery cells to sort out copper foil, aluminum foil, black powder (positive electrode material) and plastic.

Metallurgical purification: Black powder is dissolved in acid, filtered, extracted and other steps to obtain cobalt sulfate, nickel sulfate and lithium salt.

Material regeneration: The purified metal can be reused to make new batteries or other industrial uses.

Final products and economic benefits

Metal materials: Cobalt, nickel, lithium, etc. are the core raw materials of power batteries and have high market value (such as the price of lithium carbonate exceeds 100,000 yuan/ton).

Graphite and electrolyte: can be recycled after purification, reducing the production cost of new batteries.

Plastic and aluminum shells: recycled to make new battery shells or other industrial products.

Taking the production line that processes 10,000 tons of waste batteries per year as an example, the metal recovery rate can reach more than 95%, and the annual output value can reach hundreds of millions of yuan. With the improvement of battery recycling policies (such as the mandatory recycling ratio of the EU's "New Battery Regulation"), the industry will usher in explosive growth.

Lithium battery recycling equipment not only solves environmental pollution problems, but also promotes resource recycling, with both environmental protection and economic benefits. In the future, with the advancement of automation and green metallurgical technology, lithium battery recycling will become a key link in the new energy industry chain.
