Waste lithium battery processes quite troubles, throwing a lot of damage to the environment. At present, the battery is configured for electric vehicles mainly includes traditional lead-acid batteries and emerging lithium batteries, and the recycling of lithium batteries is completely different. At present, domestic lithium battery recovery is not systematic, recycled, and the technology is behind.
The endanger of the waste lithium battery is scrapped. If the treatment is improperly disposed, the hexafluorols, carbonate organics, and cobalt, copper, etc., which are contained therein, will inevitably constitute a potential pollution threat to the environment.
On the other hand, cobalt, lithium, copper and plastics in waste lithium batteries are valuable resources, with extremely high recovery value. Therefore, scientific effective treatment for waste lithium batteries, not only has significant environmental benefits, but also has good economic benefits. When the waste lithium pool is discarded, after entering nature, the heavy metals cannot be degraded by biodegradation, causing serious pollution to the environment.
According to statistics, a waste of the old battery can make the 1 square meter soil permanently lose value, and the button buckle battery can pollute 600,000 water. The hazards of the waste batter are mainly concentrated on a small amount of heavy metals contained therein, such as lead, mercury, cadmium, etc. These toxic substances enter the human body through various means, long-term accumulation is difficult to exclude, impair nervous system, hematopoietic function and bones, and even cancer.
1. Mercury (HG) has obvious neurotoxicity, and there is also a negative impact on endocrine systems, immune systems, etc., which will cause pulse, muscle fibrillation, oral and digestive system lesions; 2.
Cadmium (CD) elements enter into a variety of routes In the human body, long-term accumulation is difficult to exclude, damage the nervous system, hematopoietic function and bones, and can even cause cancer; 3. Lead (PB) can cause neurasthenia, hand and foot numbness, indigestion, abdominal colic, blood poisoning and other lesions; manganese Will hazard the nervous system. The recycling of waste lithium batteries and the booming of new energy vehicles, as well as policies and marketing, making our country a world's most important lithium-ion battery production and consumer.
A large number of lithium-ion batteries enters the market, and the problem of waste lithium-ion battery recycling and re-use has also become a major challenge in the industry. With the growth of the use time, all aspects of the capacity, discharge efficiency, and safety of lithium batteries will have a significant decline. For lithium batteries that have not been able to meet the current application requirements, the recycling can effectively exert its "remaining value".
At this stage, my country's waste lithium battery recycling system is still uncomfortable, and the recycling technology and business model have not reached a mature standard. At present, the use of technology is not mature, the acquisition network is not perfect, the management measures are not perfect, support policy is not in place, etc., the problem is still plaguing my country's lithium battery recycling industry, business model and profit model still to explore.
The system of the ladder is not perfect, still being the biggest problem facing the old battery recycling field. What extent can be reached in the battery capacity to enter the next step, how to achieve a ladder utilization and need to enter the recovery process, there is no clear criteria. At present, there is only a very small number of high-quality phosphate batteries that can be applied to the ladder, and the remaining battery includes the use of value.
After using a period of time, the ternary battery is difficult to ensure electrochemical performance of electrochemical properties in the battery, which is used for safe risks of the ladder. Grouping batteries will significantly increase costs, only if they do not disassemble battery packs. How does the waste lithium battery recycled? First, study the standardization of the battery and implement the traceability system.
Strengthen the standardization of the structural design, connection method, process technology, integrated installation of the power lithium battery, and make the power battery coding forced standards, and hook the traceability system and the new energy vehicle product announcement to ensure the full life cycle information record. , Improve the convenience and accuracy of detection evaluation. The second is to increase battery recycling key technologies.
Increased key technologies such as dismantling, reorganization, test and life prediction of waste lithium battery, improve the safety of its technical maturity and production process. At the same time, improve the automation level and recovery efficiency of battery dismantling, reorganization and recovery technology, so that power-based battery recovery is economically feasible and safe. The third is to formulate and implement power battery recovery rewards and punishment measures.
Develop a dynamic lithium battery recovery and re-use incentive implementation rules, establish a random and penalty mechanism. For example, for the punishment of companies that fail to perform responsibility obligations in the recycling policy, the battery recycling enterprises and battery reuse companies are subsidized according to the battery sets, capacity, etc., and implement tax concessions, ensuring the economics of recycling companies; for consumers The deposit and rewarding system can be used to cultivate a consciousness of consumer power battery recovery.
The fourth is to encourage business model innovation pilots and promotion applications. Actively innovate business models, reach a circular economy development model with promotion value after accumulation. Implementing the construction of powerful lithium battery recycling system, and use subsidies mechanisms and preferential policies to improve the enthusiasm of enterprises and consumers, but avoid some speculative enterprises to enter this industry in order to subsidize, form fair and benign competition mechanisms to facilitate the industry healthy growth.
Waste lithium battery environmental treatment process: coarse crusher - particulate pulverizer - micron grading machine - cyclone separator - pulse dust collector - high pressure fan, lithium battery crusher's entire recovery process all achieved industrial automation, high recovery efficiency, strong processing ability The amount of processing per hour is 500 kilograms, the annual processing volume reaches 5,000 tons, and the price of waste lithium battery is more than 90%. If the abandoned lithium battery is not systematically processed, it will seriously waste resource pollution environment and endanger human health. If the waste lithium battery can be fully recovered, 240 tons of cobalt can be recovered each year, only more than 40 million worth more than 40 million.
The development of electronic technology has brought out explosive development to the lithium battery industry. The recovery treatment of waste lithium batteries is also more and more attention. Improper waste lithium battery in our lives will bring pollution to the environment, don't be free.
