Description
Technical Field

China is a large country for producing and consuming lithium ion batteries, the service life of the lithium ion batteries is about 2-3 years, and the lithium ion batteries are huge in recycling market. In the aspect of composition, various heavy metal elements and organic compounds exist in the lithium ion battery, and if the lithium ion battery is not recycled, the lithium ion battery can pollute the environment and influence the human health. In terms of recycling value, the ternary lithium battery contains various valuable metals, such as nickel, cobalt, manganese, lithium and the like, and the content of the valuable metals is even higher than that of natural ores, so that the ternary lithium battery has extremely high recycling value. Therefore, the method has great significance for harmless recycling of the lithium ion battery.
At present, the recovery method of the lithium ion battery mainly comprises pyrometallurgy, hydrometallurgy and biological metallurgy. Pyrometallurgy requires high-temperature calcination of waste batteries, has high energy consumption, and can generate a large amount of harmful waste gas to cause environmental pollution. Hydrometallurgy needs to use a large amount of strong acid and alkali solution, can generate a large amount of waste water, pollutes the environment, simultaneously relates to operations such as leaching, extraction, precipitation and the like, and has complex working procedures. The biological metallurgy dissolves and leaches the metal ions on the anode of the lithium ion battery by utilizing the metabolism of microorganisms, but the culture period of the microorganisms is longer, and the requirement on the growth environment is high.
When the waste batteries are recycled, the waste batteries need to be disassembled and sorted, the waste lithium ion batteries are rich in residual energy, and direct disassembly can cause fire and explosion, so that the waste batteries need to be discharged. The commonly used discharge methods are physical discharge, chemical discharge and mechanical puncture discharge. Physical discharge utilizes an external circuit to release residual electricity, but the discharge speed is slow, and the efficiency is low. Chemical discharge is soaked by salt solution to generate chemical reaction and release electric energy, but electrolyte leakage is easily caused, and organic wastewater is generated. The mechanical puncture is easy to cause fire and explosion, threatens the safety of operators and damages equipment. These discharging methods have their own defects and cannot utilize the remaining energy in the battery, resulting in waste of energy.
At present, in the process of crushing, sorting and recycling lithium ion batteries, the residual energy of the batteries possibly causes fire and explosion, and meanwhile, the residual energy cannot be utilized to cause waste, so that the problems need to be solved urgently. The conventional discharge methods all have serious defects, which limit the application of the discharge methods in production.
