High economic value of recycling lithium batteries

In recent years, my country's lithium battery industry has developed rapidly, and the risk of overcapacity in the industry has begun to emerge. At the same time, the application field of lithium batteries in my country has also undergone great changes. Lithium batteries have developed from the field of electronic communication products such as mobile phones, digital cameras, and computers to new energy fields such as electricity and transportation, and have become an indispensable and important product in people's daily life. The lithium battery industry has become one of the emerging high-tech industries. The treatment of waste lithium batteries is very important, otherwise it will cause secondary pollution. The waste lithium battery treatment and recycling equipment solves this problem well, and has achieved obvious economic benefits.

Lithium batteries are electronic consumables. If the discarded lithium batteries are improperly disposed of, the lithium hexafluorophosphate, carbonate organic compounds, cobalt, copper and other heavy metals will inevitably pose a potential pollution threat to the environment. On the other hand, in waste lithium-ion batteries, cobalt and lithium present on the positive electrode are very valuable for recycling due to their high price and scarce resources. In addition, aluminum foil and copper foil as positive and negative current collectors are also valuable metals for recycling. Therefore, scientific and effective treatment and disposal of waste lithium batteries not only has significant environmental benefits, but also has good economic benefits.

Lithium battery is mainly composed of shell, positive electrode, negative electrode, electrolyte and separator. The positive electrode is formed by coating lithium cobalt oxide powder on both sides of the aluminum foil current collector through PVDF that acts as a bond; 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. Lithium battery processing equipment is a process equipment for crushing and processing lithium batteries, which simplifies the traditional recycling process of positive and negative materials in waste lithium batteries. It does not need to add any chemicals, and does not need to consider the problem of new pollutants. The process equipment flow line realizes the sustainable development of waste lithium batteries, so the utilization of positive and negative sheet metals in the separation and recovery of waste lithium batteries is promising.
