Lithium Battery Recycling Production Line Scrap Battery Recycling Equipment
Product Description:
Lithium Battery Recycling Production Line is designed to process spent lithium-ion batteries from various applications, including electric vehicles, consumer electronics, and energy storage systems. It can handle different LIB chemistries such as lithium cobalt oxide (LCO), lithium nickel manganese cobalt oxide (NMC), lithium iron phosphate (LFP), and lithium nickel cobalt aluminum oxide (NCA). The system consists of a pretreatment unit for disassembly, shredding, and size reduction of the battery components to a 5-50 mm particle size range.
Features:
1. Comprehensive recycling: Lithium battery recycling equipment comprehensively recovers valuable metals and materials from used lithium batteries, including cobalt, nickel, lithium, copper, aluminum and steel, etc., to maximize the utilization of resources.
2. Harmless treatment: Through processes such as heat treatment, physical separation and chemical leaching, toxic and harmful substances such as heavy metals and electrolytes in lithium batteries are safely separated and harmlessly treated to avoid secondary pollution.
3. Automated control: Lithium battery recycling equipment is equipped with PLC control system, human-machine interface, etc., to achieve fully automated operation, improve production efficiency and stability, and reduce manual operations.
4. Environmental protection and emission standards: The lithium battery recycling equipment system strictly implements environmental protection to ensure that exhaust gas, waste water and solid waste meet relevant emission standards and achieve clean production.
5. Energy saving and environmental protection: The use of advanced technology and efficient equipment is conducive to saving energy and reducing carbon emissions, embodying the concept of environmental friendliness.
Lithium Battery Recycling Production Line Working Principle:
1. Preprocessing
First, the collected waste lithium batteries are sorted, disassembled and crushed. The battery is disassembled into components such as the casing, positive electrode material, negative electrode material, separator and electrolyte, and broken into appropriate particle sizes in preparation for subsequent extraction.
2. Heat treatment
There are two main ways to heat-treat pretreated battery materials in a high-temperature environment:
a) Roasting - Roasting in an oxidizing atmosphere at 500-800°C to burn and decompose organic matter (such as separators, electrolytes, etc.), and at the same time separate the positive active material from the aluminum/copper foil.
b) Thermal cracking - thermal cracking in an inert atmosphere (such as nitrogen) at 300-600°C to decompose the negative electrode graphite into a variety of carbon species while removing other impurities in the active material.
3. Physical separation
The valuable metals in the heat treatment product are separated through physical methods such as magnetic separation, air separation, and gravity separation:
a) Magnetic separation - uses a magnetic field to separate ferrous metals (such as steel shells).
b) Air separation - uses air flow to separate light particles (such as carbon and some alumina) from heavy particles.
c) Gravity separation - Use the density difference of the medium to separate valuable metals (such as Cu/Al) from other components.
4. Hydrometallurgy
The enriched metals are subjected to hydrometallurgical extraction and purification processes. Includes the following main steps:
a) Leaching - Dissolving target metals (such as cobalt, nickel, lithium, etc.) into acid or alkali solutions.
b) Purification - remove impurity ions through solvent extraction, ion exchange and other methods.
c) Electrodeposition - Using the principle of electrolysis, the target metal ions are reduced and precipitated to obtain high-purity metal products.
5. Exhaust gas treatment
The entire recycling process will produce some exhaust gas and dust, and dust collectors, scrubbers and other equipment need to be used to purify the exhaust gas to ensure that emissions meet standards.
Finally, valuable metals and materials such as cobalt, nickel, lithium, aluminum, and copper can be recovered from used lithium batteries to achieve resource reuse. The process runs through the physical and chemical separation and extraction principles, and pays attention to environmental protection and safety.
