Machine de recyclage Batteries Lithium

Battery experts and environmentalists give a long list of reasons to recycle Li-ion batteries. The recovered materials could be used to make new batteries, reducing manufacturing costs. In many types of Li-ion batteries, the concentrations of metals, as well as lithium and manganese, exceed the concentrations in natural ores, making the spent batteries resemble highly enriched ore. Currently, research into recycling lithium battery waste focuses primarily on recovering the high-value positive precious metals, cobalt and lithium.

Lithium-ion battery composition

According to the analysis of the material composition of lithium-ion battery, it contains a lot of precious metals. Take the cell phone battery as an example, which contains 15% cobalt, 14% copper, 4.7% aluminum, 25% iron and 0.1% lithium. In 2006, the prices of cobalt, nickel, copper and aluminum reached 315,000, 312,600, 66,888 and 219.64 million yuan/ton respectively. The recycling of lithium-ion battery waste will bring considerable economic benefits.

 

Lithium-ion battery composition

The lithium battery is mainly composed of a casing, a positive electrode, a negative electrode, an electrolyte and a diaphragm.

• The anode is formed by coating lithium cobaltate powder on both sides of an aluminum foil current collector through PVDF which plays a bonding role;
• The structure of the negative electrode is similar to that of the positive electrode, and the carbon powder is bonded to both sides of the current collector of the copper foil.
• Based on the structural characteristics of lithium batteries, our company adopts environmental protection physical separation process to realize efficient separation and recovery of lithium battery waste.

Scrap Lithium-ion Battery Recycling Production line

Brief introduction of equipment functions: At present, the research on recycling of waste lithium batteries mainly focuses on the recovery of high-value anode precious metals cobalt and lithium. The copper in the negative electrode of waste lithium batteries (content of up to 35%) is a widely used important production raw material. Based on the structural characteristics of lithium batteries, our company adopts an environmentally friendly physical separation process to realize efficient separation and recovery of waste lithium batteries. The pretreatment process of scrapped lithium batteries is mainly to recycle waste batteries. After discharge, mechanical equipment is used for breaking, magnetic separation, air separation, crushing, gravity separation, screening and other processes, so that the powder on the anode and cathode can be effectively separated from the copper and aluminum foil. Raw Material Iphone Battery Li Ion Battery Recycling Equipment is used for dismantling and recycling software battery pack, mobile phone battery, shell battery, cylindrical battery, etc. Different types of lithium batteries have different recycling procedures. TECHNOLOGY PROCESS: Crusher — Hammer Crusher — Grinding Machine — Separating Machine — Pulse Dust Collector — Screen Classification — Magnetic Machine — Gravity Separator — High Pressure Fan Working Principle of the Machine:

• Conveyor:

Transport batteries to the shredder, crusher or grinder.

• Hammer crusher:

Crush the batteries into small pieces and separate the battery cover, cathode and anode material in the meantime.

• Crusher:

Shred completely discharged batteries.

• Conveyor:

Transport the material to the next machine after crushing.

• High magnetic separator:

After crushing the battery, the magnetic separator will remove the ferrous metal inside the material.

• Vibrating screen classifier:

Separate the material according to the size. Will get several kinds of materials according to the size.

• Separating machine:

Separate the material according to its weight. Separate the lighter material (powder) from the heavier material (metal).

• Pulse dust removal system:

Collect dust and plastic material after crushing during operation, purify the air and provide a good working environment.

• Induced draft fan:

The airflow is generated by the rotation of the turbine to collect and discharge dust or materials in the operation of the equipment.

• Moulin:

Through the high-speed operation of the broken material or the anode and cathode plate for a hit, so that the anode plate and the active material separate.

• Air flow separator:

According to the density of the materials, the mixed materials of metal particles and powder separated by the vibrating screen classifier are sorted. The weight of copper metal is greater than that of aluminum metal to realize the separation of copper and aluminum.
