How about lithium battery crushing recycling equipment

Time:2021-02-24 10:34 Author:Suny Group

Lithium battery crushing and recycling equipment mainly uses physical recycling methods, supplemented by "three wastes" disposal measures. It has the characteristics of green, low-carbon, energy-saving and environmental protection, and no secondary pollution. It also takes into account economic and environmental benefits, and realizes the use of valuable components. It can also harmlessly treat harmful components. The entire recycling process has realized industrial automation, with high recycling efficiency and strong processing capacity, with an hourly processing capacity of 500 kilograms, an annual processing capacity of 5,000 tons, and a recycling rate of more than 90% of valuable components of waste lithium batteries.

Lithium Battery Recycling Machine

Cobalt, lithium, copper and plastics in waste lithium batteries are precious resources and have high recycling value. Therefore, scientific and effective treatment of waste lithium batteries not only has significant environmental benefits, but also has good economic benefits. Lithium batteries are mainly composed of a shell, a positive electrode, a negative electrode, an electrolyte, and a separator. The positive electrode is formed by coating lithium cobalt oxide powder on both sides of the aluminum foil current collector through PVDF which plays a role of binding; the negative electrode structure is similar to the positive electrode, and is composed of carbon powder bonded to both sides of the copper foil current collector.

At present, the research on the recycling of waste lithium batteries is mainly focused on the recovery of valuable cathode precious metals cobalt and lithium, and there are few reports on the separation and recovery of anode materials. In order to alleviate the increasingly serious resource shortage and environmental pollution problems caused by the rapid economic development, it has become a global consensus to realize full-component recycling of waste materials. The copper in the negative electrode of waste lithium batteries (with a content of about 35%) is a widely used important production raw material, and the carbon powder adhered to it can be used as an additive for plastics, rubber, etc. Therefore, the effective separation of the negative electrode constituent materials of the waste lithium battery has a driving effect on the limited realization of the recycling of the waste lithium battery and the elimination of its corresponding environmental impact. Commonly used waste lithium battery recycling methods include hydrometallurgy, pyrometallurgy and mechanical physical method.

Compared with the wet method and the fire method, the mechanical physical method does not require the use of chemical reagents and has lower energy consumption. It is an environmentally friendly and efficient method.

Advantages of lithium battery crushing and recycling equipment:

1. Pure physical sorting, no pollution, no environmental protection pressure;

2. Simple operation, labor-saving and high-efficiency, low operating cost, good effect of one-time sorting;

3. Special equipment with larger output can be customized according to customer needs.
