Performance Of Lithium Battery Recycling Equipment

Cobalt, lithium, copper and plastic in waste lithium batteries are valuable resources with high recycling value. Therefore, the scientific and effective treatment and disposal of waste lithium batteries - lithium battery recycling equipment, not only has significant environmental benefits, but also has good economic benefits. Lithium battery is mainly composed of shell, positive pole, negative pole, electrolyte and diaphragm, PVDF lithium cobalt oxide powder coated on both sides of the aluminum foil collector; negative pole structure and positive pole is similar to the positive pole through the role of bonding by the carbon powder bonded to both sides of the copper foil collector composition.

At present, the realization of recycling of waste batteries mainly focuses on the recovery of high-value cobalt and lithium, the precious metals of the positive electrode. In order to alleviate the increasingly serious resource shortage and environmental pollution problems caused by rapid economic development, it has become a global consensus to realize whole-component recycling of waste materials.

Waste lithium battery negative electrode in the copper (content of 35% or so) is a widely used important raw materials for the production of carbon powder adhered to the above, can be used as plastics, rubber and other additives. Therefore, effective separation of waste lithium battery negative electrode constituent materials can maximize the resourcefulness of waste lithium batteries and eliminate the negative impact of waste batteries on the environment. Commonly used methods of waste lithium battery resources include hydrometallurgy, pyrometallurgy and mechanophysical methods. Compared with wet and fire methods, mechanophysical method is an environmentally friendly and efficient method, which does not require the use of chemical reagents and consumes less energy. Based on the structural characteristics of lithium battery negative electrode, we adopt a combination of crushing, screening and airflow sorting process to separate and enrich it, in order to realize the efficient separation and recovery of copper, aluminum and carbon powder from waste lithium battery negative electrode.

The lithium battery recycling equipment has a wide range of applications and can handle many types and different specifications of waste lithium batteries, which is an efficient recycling equipment.
