The value of lithium batteries

From the current technology perspective, if the usability of used lithium batteries is very low, there is no specialized technology that can bring greater benefits; Due to the presence of heavy metals and chemical components inside discarded lithium batteries, special treatment is necessary to prevent environmental pollution. Currently, the technology is not very mature.

For the use of waste lithium batteries, we know that cobalt, lithium, copper, and plastics in waste lithium batteries are valuable resources with extremely high recycling value. Therefore, scientific and effective treatment and disposal of waste lithium batteries not only have significant environmental benefits, but also have good economic benefits. To alleviate the increasingly serious resource shortage and environmental pollution caused by rapid economic development, achieving full component recycling of waste lithium batteries has become a global consensus.

Waste lithium batteries mainly consist of a casing, positive electrode, negative electrode, electrolyte, and separator. The positive electrode is composed of lithium cobalt oxide powder coated on both sides of the aluminum foil collector through PVDF that acts as a bonding agent; The negative electrode structure is similar to the positive electrode, consisting of carbon powder bonded to both sides of the copper foil current collector. The commonly used methods for recycling waste lithium batteries include hydrometallurgy, pyrometallurgy, and mechanical physical methods. Compared to wet and pyrometallurgical methods, lithium battery crushers use mechanical and physical methods without the need for chemical reagents, and have lower energy consumption, making them an environmentally friendly and efficient method.

At present, about 100 million mobile phone batteries are scrapped each year, with an average weight of about 20g per battery. The cobalt content is about 3g or more, and the current price of metallic cobalt is 400000 yuan/ton. Each ton of discarded batteries can recover more than 160 kilograms of metal, worth 64000 yuan. The recycling value of cobalt alone in the country can reach hundreds of millions of yuan. Aluminum, copper, and organic electrolytes can also be recovered from discarded lithium-ion secondary batteries, all of which have high value. The cost of resource recycling mainly includes the electricity consumption, labor costs, raw materials, transportation costs, and enterprise management fees for the operation of mechanical equipment, as well as the cost of recycling waste batteries. Supported by an effective system for recycling discarded mobile phone batteries, the expected annual processing capacity is 100 tons, with an annual sales revenue of at least 22.5 million yuan and a profit and tax of 4.5 million yuan. Recycling discarded lithium-ion batteries can achieve material recycling, which has significant social significance.

The production line for the treatment of waste lithium battery positive and negative electrode plates abandons traditional high energy consumption and high pollution recycling technologies such as pyrometallurgy and hydrometallurgy. It mainly adopts physical recycling methods, supplemented by "three wastes" disposal measures. It has the characteristics of green and low-carbon, energy conservation and environmental protection, no secondary pollution, and takes into account economic and environmental benefits. It not only realizes the utilization of valuable components, but also harmless treatment of harmful components. The entire recycling process has achieved industrial automation, with high recycling efficiency and strong processing capacity. The hourly processing capacity is 500 kilograms, and the annual processing capacity reaches 5000 tons. The valuable component recycling rate of waste lithium batteries is over 90%. With the increasingly widespread application of lithium-ion batteries, recycling valuable metals from lithium-ion batteries, reducing environmental pollution, and alleviating resource scarcity have important social and economic significance.

Through research on the recycling and utilization of waste lithium-ion batteries, it can be found that the recycling methods mainly focus on the recycling and utilization of positive electrode active substances in the battery. In summary, according to the different key technologies and principles of recycling, the recycling and treatment technology of waste lithium batteries can be divided into three treatment methods: physical method, chemical method, and mechanical method. The lithium battery crusher equipment produced by Yingtong uses a coarse crusher to crush the raw materials to 10mm or less, then enters a particle crusher for stripping and crushing, and finally enters a micro powder classifier for separation and treatment. The tail ash is collected by a cyclone separator and a pulse dust collector in the rear channel. The waste lithium battery positive and negative electrode plate processing equipment is based on the material characteristics of copper and carbon powder, which are the positive and negative electrode structures of lithium batteries. It uses a combination process of hammer vibration crushing, vibration screening, and airflow sorting to separate and recover the negative electrode composition materials of waste lithium batteries. The complete set of equipment operates in a negative pressure state, without dust leakage, and the separation efficiency can reach over 98%.

Yingtong Machinery is a professional manufacturer of waste lithium battery treatment equipment. Its lithium battery crusher equipment is mainly used by lithium-ion battery manufacturers to separate and treat aluminum, copper, and positive and negative electrode materials in scrapped positive and negative electrode plates for the purpose of recycling. The entire production line operates under negative pressure, and there is no dust leakage during the production process. The production environment is cleaner and more environmentally friendly, and the dust emission concentration meets environmental requirements. This crushing equipment scientifically and effectively treats and disposes of waste lithium batteries, which not only has significant environmental benefits, but also has good economic benefits. Our factory welcomes customers from all over the world to come and inspect, conduct on-site testing, and purchase genuine lithium battery recycling and processing equipment upon arrival.
