Recycling rate of waste lithium ion battery, harm of waste lithium ion batteries. The demand for power lithium batteries is constantly increasing, predicted that the waste volume of the waste lithium-ion battery in my country will reach 120,000 T to 200,000. In terms of the actual situation, there are few companies that recycle waste lithium-ion batteries.

People do not understand the recycling method of lithium-ion batteries, so that the recovered lithium-ion battery cannot be effectively applied. Waste lithium ion battery recovery rate my country's lithium-ion battery is added in a new state of incrementing, and it is expected to continue to rise. As is well known, the life of the lithium-ion battery is generally 2 to 3 years.

What should I deal with when so many lithium ion batteries reach the upper limit? Due to technical and economic, the current recovery rate of lithium-ion batteries is very low, and a large number of waste lithium-ion batteries are abandoned, which causes huge threats and pollution to the environment. At the same time, it is also a waste of resources. Therefore, how to control "battery pollution "At the same time, realize the comprehensive cycle recycling of waste batteries, especially cobalt, has become a hot problem for social concern.

Since my country's recycling of the incomplete and recovery of the lithium-ion battery industry chain is not in place, the waste lithium ion battery recovery rate is less than 2% of its scrap volume. Therefore, resource, harmless treatment and pollution control of waste lithium ion batteries have become a task. The valuable material in the lithium battery cell is maximized, with the copper aluminum metal recovery rate of 98%, and the recovery rate of the lithium-ion battery positive electrode material exceeds 90%.

Lithium-ion battery separation recovery equipment is an important use of physical recovery methods, supplemented with "three waste" disposal measures, with green low-carbon, energy-saving and environmental protection, no secondary pollution, and taking into account economic and environmental benefits, lithium-ion battery separation recycling equipment is only realized The utilization of value components can be harmless to harmful components. The entire recycling process has achieved industrial automation, high recovery efficiency, strong processing capacity, and lithium-ion battery separation recovery equipment to process waste lithium ion battery price components of recovery rate of more than 99%. The harm of waste lithium ion batteries contain a variety of toxic substances, with strong corrosive and pollution.

In addition, the waste lithium-ion battery electrolyte contains very poisonous, flammable and explosive, corrosive electrolyte and organic solvent. The electrolyte is important to include LIPF6, LiBF4, Liclo4, LiASF6, etc., etc.

, produce HF, PF5 and other toxic substances, and fluorofluorocystosis and arsenic pollution. Waste dynamic lithium-ion battery dismantling will cause pollution such as exhaust gas, waste liquid and waste, which may cause hazardous hazards of ecological environment, even endanger health, not recycling and dealing with resources. Increase key technical research on disassembly, recombination, test and life prediction of waste, reorganization, test and life prediction, improve technical maturity and production process, and automation level and recovery efficiency, so that the power lithium-ion battery recovery is economically feasible Sexuality and safety.

In addition, there will be a series of contaminants during crushing, high-temperature thermal extracts, such as the decomposition of the electrolyte, the thermal solution of the electrolyte, the pyrolysis of the plastic film, the dust, waste residue, etc., these pollutants are not only For the atmosphere, the water body causes serious pollution and has serious corrosive equipment. Summary: The large-scale dynamic lithium-ion battery market will be associated with lithium-ion battery recycling and downstream tradder utilization industry opportunities, developing lithium-ion battery recycling and ladder use in preventing resource waste and environmental pollution, will also have considerable economic benefits and Investment Opportunities.

Therefore, research significance for the recovery technology of waste lithium ion battery. .
