Overview:​For the use of waste lithium batteries, we know that cobalt, lithium, copper and plastics in waste lithium batteries are precious resources and have very high recycling value. Therefore, scientific and effective disposal of waste lithium batteries not only has significant environmental benefits, but also has good economic benefits. In order to alleviate the growing shortage of resources and environmental pollution caused by rapid economic development, it has become a global consensus to recycle all components of waste lithium batteries.

Waste lithium batteries are mainly composed of shell, positive electrode, negative electrode, electrolyte and diaphragm. The cathode is composed of lithium cobalt powder coated on both sides of the aluminum foil collector by PVDF, which acts as a bonding agent. The structure of the cathode is similar to that of the cathode and consists of carbon powder bonded on both sides of the copper foil collector. For the recovery and utilization of waste lithium batteries, the commonly used methods of reclamation of waste lithium batteries include hydrometallurgy, pyrometallurgy and mechanical physics. Compared with the wet and pyrometallurgical methods, lithium battery crusher is an environmentally friendly and efficient method, which does not need chemical reagents and consumes less energy.

At present, about 100 million mobile phone batteries are discarded every year, and the average weight of each battery is about 20g. The cobalt content is about 3G. At present, the price of cobalt metal is 400,000 yuan/ton. The metal can be recovered more than 160 kilograms per ton of used batteries, which is worth 64,000 yuan. The recovery value of cobalt alone in China can reach hundreds of millions of yuan. Aluminum, copper and organic electrolytes can also be recovered from waste lithium ion secondary batteries, which are of high value. The cost of recycling is mainly the power consumption, labor costs, raw materials, transportation costs and enterprise management costs of the operation of machinery and equipment, and the cost of recycling used batteries. Supported by an effective recycling system for waste mobile phone batteries, it is expected that the annual disposal capacity will be 100 tons, the annual sales revenue will reach at least 22.5 million yuan, and the profit and tax will reach 4.5 million yuan. The recycling of waste lithium-ion batteries can realize the recycling of materials, which is of great social significance.


The waste lithium battery positive and negative plate treatment production line has abandoned the traditional pyrometallurgy and wet process and other high energy consumption and high pollution recycling technology. It mainly adopts physical recycling method, supplemented by "three wastes" disposal measures. It has the characteristics of green, low carbon, energy saving and environmental protection, no secondary pollution, and takes into account the economic and environmental benefits. The use of valence components can also make harmless treatment of harmful components. The whole recovery process has realized industrial automation, high recovery efficiency and strong processing capacity, with an hourly capacity of 500 kg, an annual capacity of 5000 tons, and a recovery utilization rate of valuable components of waste lithium batteries of more than 90%. With the increasing application of lithium-ion batteries, it is of great social and economic significance to recover valuable metals from lithium-ion batteries, reduce environmental pollution and alleviate resource shortage.


Through the research on the recycling of waste lithium-ion batteries, it can be found that the recycling methods of waste lithium-ion batteries are mostly concentrated on the recycling of positive active substances in batteries. In summary, according to the main key technologies and principles of recovery, waste lithium battery recovery and treatment technology can be divided into physical, chemical and mechanical methods. Lithium battery crusher equipment produced by Yingtong crusher crushes raw materials to less than 10 mm, then enters the particle crusher for peeling and crushing, and then enters the micro-grinding classifier for separation and treatment. The tail ash is collected by the back-channel cyclone separator and pulse dust collector. Based on the structure of positive and negative poles of lithium batteries and the material characteristics of copper and carbon powders, the equipment adopts the combined process of hammering crushing, vibration screening and air separation to separate and recover the negative poles of waste lithium batteries. The equipment operates under negative pressure and has no dust leakage. The separation efficiency can reach over 98%.
