Dynamic lithium-ion battery recycling technology is lacking

Recently, "The Decomposition Specification for Car Power Lithium Ion Battery Recycling" (hereinafter referred to as "Decomposition Specification") and "The Equipment Test of Car Power Lithium Ion Battery Recycling" (hereinafter referred to as "Residual Test") National Standard Conference is officially held. With the advancement of the publicity, the problem of dynamic lithium-ion battery recovery is expected to be partially treated. After my country's 2013, new energy vehicles entered the rapid development period.

According to estimate, by 2020, the battery scrap will usher in the peak, and the accumulated scrap will reach 120,000 to 170,000 tons, but currently in the power lithium-ion battery recycling is the category, no matter Is the pattern, or the technical and regulations are extremely lacking. A sales personnel of the Beijing sold new energy vehicle 4S shop said to reporters that at present, the manufacturer does not have relevant policies for battery recovery, so the scrapped battery is generally solved by 4S shop. Not only the problem of recycling channels, the power lithium-ion battery reuse technology is not mature, but the process is too complicated, the cost is too high, which also causes great resistance to the power lithium-ion battery recovery.

One dynamic lithium-ion battery industry insiders said that if it does not launch the relevant preparation, the future of the dynamic lithium-ion battery will be due to serious environmental issues. The main body of the recycling is clearly enforced, "dismantling standard" will be officially implemented on December 1, this year, and "余能 测试" is also expected to officially announce the implementation next year, which will have a blank power for the current standard. Ion battery recycling market has improved to a certain degree of improvement.

"At present, battery recycling market is more messy. "Wang Xiaojian, the technical management department of SAIC Group Co., Ltd.

, said to the reporter that there is no compassion on the recycling of the scrap dynamic lithium-ion battery, the country is currently not enforced, the main plant, the battery factory, and the dismantling plant have not found appropriate operation mode. In the Ningde Times, insiders told reporters that the current life of the power lithium-ion battery is 7 ~ 8 years. The reporter visited Beijing's new energy 4S store.

At present, the new energy car uses the dynamic lithium-ion battery warranty year. The consumer needs to pay for the battery after 8 years. In fact, last year, the National Development and Reform Commission, the Ministry of Industry and Information Technology, etc.

And the steps of the battery processing company should bear the important responsibility of the driving battery recycling and utilization of each processing, and the scrapped car recycling dismantling company should be responsible for recycling the power battery on the scrapped car. According to this regulation, theoretically, the main plant should bear the responsibility of recycling the waste battery from the 4S shop, and the scrapped battery detached from the scrapped car shall be carried out by the battery factory and other companies, and finally the scrapped factory is scrapped. However, the insiders in Ningde Times told reporters that this provision only clarified the responsible subject, and did not require enforcement, so, the power lithium-ion battery recovery did not excellent according to the above requirements.

One of BYD also confirmed the statement to the reporter. It said, because the current regulations have no mandatory requirements for the recycling of power lithium ion batteries, BYD, such as a vehicle enterprise involving battery services, and does not involve the new energy vehicle enterprise of the battery business, most of which have not been a clear requirement for recycling. Cultural high-class integrated reuse costs are not only recycled, but there are many problems in the battery after recovery.

According to the plan, the retardation should be carried out after recovery from the scrap battery dismantled by the car, but the internal person of the Ningde Times told reporters that due to the formation of scale, the current battery dismantling is basically in the loss. The research report of the hundred people in my country's electric car shows that a company with mechanical law and wet recovery of iron-free phosphate ion batteries, recycling 1 ton of waste phosphate dynamic lithium-ion battery costs of 8540 yuan, while regeneration materials Only 8110 yuan, loss of 430 yuan. Wang Xiajian told reporters that in addition to cost, process complexity is also another problem with the recycling of dynamic lithium-ion batteries.

It is understood that, at present, the type of power lithium-ion battery in the market is complicated. There are different manufacturing and design of different types of batteries, and the form is different in series, the service and use time are different, and the use of models and use conditions is different. The process of sexually reused reuse is extremely complex.

Because there are many problems, my country's powered lithium-ion battery recycling is currently in the exploration stage, which also leads to partial powered lithium-ion batteries that have not been recovered and resolved but is discarded. It is understood that although most of the power lithium-ion battery is a lithium-ion battery, if it is random discard, it will pollute the environment. Wang Xiaojian said that the organic matter in the dynamic lithium-ion battery belongs to toxic substances, with strong cancer, and will discard serious consequences.

my country's new energy vehicles enter sales rapid rising period after 2013. At present, most of the dynamic lithium-ion batteries on the market have not yet entered the scrap period, but it can be calculated that by 2020, the dynamic lithium-ion battery scrap will gradually appear. my country's electric car hundreds of people will show content show that before and after 2020, my country's powered lithium-ion battery will reach 120,000 to 170,000 tons.

Therefore, before the peak of the scrap peak, the construction and development of regulations, technologies, etc., which are important for future healthy development of new energy vehicles.
