As of the end of last year, my country's new energy car ownership has reached 1.8 million, and some new energy vehicles entering the market have entered the scrap recycling stage. Data show, expectation to 2020, my country's powered lithium-ion battery accumulated drain will reach 120,000 to 170,000 tons.
The value of recovery market created by recovery of cobalt, nickel, manganese, lithium, iron and aluminum and aluminum in waste dynamic lithium-ion batteries will exceed 5.3 billion yuan in 2018. More than 10 billion yuan will be more than 10 billion yuan in 2020.
The size of the battery market will reach 25 billion yuan. Under this premise, the problem of the recycling of the power lithium-ion battery also floats the surface. At present, the dynamic lithium-ion battery recycling is chaotic, and the emergence of these chaos is not just the problem of retaining a single link, but the entire industrial chain.
Based on this, the newspaper has planned a series of "Power Lithium Ion Battery Recovery Recycling", from the multi-angle investigation, understand the true state of the dynamic lithium-ion battery scrap recovery. Previously, in order to protect the recycling of the power lithium-ion battery, the Mid-Automobile Technology Service Center announced the "Notice on the opening of the automobile power battery coding filing system", hoping to pass the "Automotive Battery Coding Record System" to achieve chasing trace. The Ministry of Industry and Information Technology, the Ministry of Science and Technology, and the Ministry of Environmental Protection, etc.
, the "Interim Method for Recycling Management" (hereinafter referred to as "Interim Method") announced in January 26 (hereinafter referred to as "Interim Method"), also emphasizes the battery to identify As a round of recycling to form closed loop management. However, this system is also recognized by the industry, and many people think that it is difficult to achieve the ideal state during execution. During the national two sessions, Zhang Tianshi, the Chairman of the National People's Congress and the Chairman of Tianneng Group, pointed out that the scanning code system to be implemented will not be able to scan code once battery deformation or encoding is arbitrarily altered.
At the same time, if the scan code is used in the whole process of sales, collection, transfer, disposal, a large amount of manpower and material will be consumed. In this regard, Zhang Tianshi has calculated a bill, for example, a regeneration company with a disposal ability is 300,000 tons, a year, according to 10 months, and dispose of 1,000-ton electric vehicle battery, which is about 220,000 per day, and Scan code can only scan 3,500 per day, more than 80 people. Therefore, this scanning code is operative.
The execution of the universal key coding system really allows the closed-loop management to form, and is effective in recovering the power lithium-ion battery? In this regard, Zhang Ying, Secretary General of my country's Recycling Resource Recycling Association, said: "The originality of the loss of dynamic lithium-ion battery is multifaceted, the coding system can be controlled from the source, through the traceability to build new energy vehicle power battery products source Observe, go to the chasing, node controllable full life cycle traceability management system, this is also the "interim method" purpose. "The establishment of the coding system, to a certain extent, supply a refined implementation according to the downstream company, battery factory and government regulatory authorities, undoubtedly let the original chaos have no chaos, and the healthy development of the industry has Positive significance, and far-reaching effects on environmental protection. That lithium research chief breakdown Mo Ca also believes that under the current technical and management conditions, the code is the most suitable way to ensure the full life cycle of the power lithium-ion battery.
However, Zhang Ying also emphasized that due to the complexity and variability of the dynamic lithium-ion battery recovery, such as tax, market supervision, etc. Mutual cooperation. Cui Dongshu, secretary-general of the National Passenger Market Information Conference, also said that once the power lithium-ion battery enters the recovery link, especially the ladder utilization or scrapping, the encoding is difficult to effectively control.
According to the current management measures, the battery cells (battery cells), modules, and battery packs must be encoded, and this manner also has a vehicle power lithium-ion battery group at three levels while forming a regulatory closed-loop industry chain. The problem of encoding, even in the ladder utilization link is very likely to have a second coding problem. "Once the power lithium-ion battery is retired as a car battery, enter the scrap recovery process, such as the ladder utilization link, there will be a problem that the battery pack reorganization and re-coding.
Secondary encoding or new management difficulty. "Cui Dongshu explained. Behind the scan code system is more than the battery deformation or coding of Zhang Tianshi or coding cannot perform scanning code and a large number of scan code work will have an additional cost.
Many industry insiders deeply recognize. In fact, currently, the encoding has run through all of our lives, Zhang Tian reluctant to see the question in our daily lives. Supermarket checkout scan code, can't be scanned due to corrosted wrinkles or unclear, etc.
Workload . Once the power lithium ion battery enters the scan code, these problems seem to be unable. "Taking 18650 lithium-ion batteries as an example, the battery plant processing monomer, PACK (battery pack) plant will combine multiple monomers, gradually form a module, and multiple modules are set as a Pack for vehicle factory.
Use, finally enter the consumer hands. In the decommissioning and ladder utilization link, the entire powered lithium-ion battery starts in reverse change, a Pack wants to be a single module, and each module may be disassembled into a single string, and the monopoly can be re-established. New Module, no use value will be disassembled, restored to the initial state, and then completely dismantled into materials.
Therefore, from the perspective of morphological changes, the coding system of the power lithium-ion battery is much more complicated than our common products. "Zhang Ying told the" my country Automobile News "reporter, the code system brings the most straightforward problem to the company that the cost of information entry is added, the amount of data encoded is too large, and the encoding of the monomer does not necessarily continue to continue. How to encode this question is to consider carefully, it is necessary to have enough useful information, but also add too much cost, do not leave a vulnerability.
There will be many difficulties in the actual operation in front of such a huge data. It should be noted that the use of an electric car is approximately approximately 5 to 10 years, and will be scrapped, that is, the power lithium-ion battery code should be followed by electric vehicles 5 to 10 years later, enter the ladder or Scrapped recycling link. During this period, the chance of encoding is not complete, and once there is a new technology or model, the current coding can be successfully scanned after 5 to 10 years, as if it is not known.
At the same time, due to the different battery models, plus the manufacturers, the code is inevitable, and the database management behind the power lithium-ion battery is also a major test. The implementation of the encoding system is to enhance supervision efficiency, however, who will supervise? What is going to regulate? Taking the drug electronic supervision code as an example, the government regulatory has a technical unprofessional and data-seeking problem; if the third party supervision can serve the public, the credibility is also what is also a problem. How to solve the code puzzle? Zhang Ying believes that accompanied by the establishment and improvement of the power lithium-ion battery recovery system, it can process the cost problem and the problem behind the coding system from a certain extent.
For example, with the improvement of the recycling system, an old battery is recovered, as long as the body is scanned, do not enter the monomer number one by one, so that a car can scan the code once or several times. Trace source. "Battery coding seems to be car frame number or engine number, the frame number of registration is convenient for managing the circulation of the car, the battery coding is also.
Of course, it is not possible to eliminate a very small number of altered coding behavior, but I think it is not enough to affect market regulations. "Zhang Ying said that the coding system can indeed help closed-loop management to promote the effective management of the dynamic lithium-ion battery from processing to the scrapped recycling, but it is not unfair to bring a series of problems. To handle related issues, improve the relevant issues.
Management efficiency. In an interview with "my country Motor News" Problem, and how these problems can be better to handle, and continue to explore in development. "We are not paying attention to some management issues brought by scanning code, which ensures that the monitoring use of the dynamic lithium-ion battery life cycle is more important.
"Mo Ca said," For example, the dynamic lithium-ion battery market, some vehicles reported that the system of the Industry and Information Technology is 30 ¡ã C, but the actual installation is 28 ¡ã C, which also damages the benefits of consumers while being repaid. At present, we have to deal with like this, this is a matter of contradictory, after this, other issues are discussed again. "Zhang Ying also believes:" In actual operation, the code category has added the workload during the processing of the dynamic lithium-ion battery, but the processing of data storage is only invested, and it will not become a large bottleneck.
Start grading from the basics, there is also a small management of the company's own management. Of course, it is also called on countries to give certain subsidies or policy dividends to alleviate the company's upgrade pressure. "In addition, Zhang Yingti, the power lithium-ion battery achieves closed-loop management, in addition to the coding system, there can be more attempts.
Such as specification of battery processing standards, build battery recycling systems, apply for national policies support, popularize national recovery, enhance market behavior supervision, etc. "These can have prompted battery legally compliant processing, use and recycling, and then use. We can also take measures while implementing the coding system.
Zhang Ying said.
