With the first batch of new energy automobile power lithium-ion batteries enter the scale of retirement, how to properly recover the topic of social concern. Some retired dynamic lithium-ion batteries fail to enter the standard recycling company, and even more influent into small workshops, the power lithium-ion battery contains a variety of heavy metal elements, and improper treatment is not conducive to resource recovery, which will also cause safety hazards and environmental pollution. "We produce new energy vehicles for environmental protection, if the power lithium-ion battery is not properly recycled, it has deviated from the original intention of this industry.

"Zhao Xiaoyong, general manager of Beijing Saidimei Resources Researcher Co., Ltd. Standardizing the number of retired dynamic lithium-ion battery recovery companies, the cost is higher, and the data released by the recovery link is announced by the Competitive Disadvantages Public Security Department, the new energy vehicle has risen more than 1 million in three years, and this year will register new energy in the first half of this year.

The car reached 11.03 million, up 234.92% year-on-year.

As of the end of June, the national new energy vehicle guarantee has exceeded 60,3000 vehicles. Xu Yanhua, the special deputy secretary-general of the Automobile Industry Association, believes that the current most solved is the problem of retired dynamic lithium-ion battery recovery. The reporter tried to search for keywords such as "Power Lithium Ion Battery Recycling", and found that there are many channels that are recycling, including online procurement platforms, second-hand trading platforms, and even some "new energy car owners" groups also have recycling companies.

It is understood that according to the provisions of the relevant departments, the use of waste-powered lithium-ion batteries should standardize the transfer to the comprehensive utilization company for ladder use or regeneration, and the recycled service outlet shall not be unauthorized for the collection of waste power lithium-ion batteries in addition to safety inspection. But in fact, the recycling and disassembly treated small workshop has always existed. On the one hand, the number of standard recycling companies is not much.

In 2018, the 2021st Office of the Department of Working has published a list of companies in accordance with the comprehensive utilization of new energy vehicles for use, a total of 27 companies, divided into two categories of ladder utilization and regeneration, and is known as whitelists by the industry. The industry is generally reflected, the number of white lists is too small, unable to meet the needs of recycling market. On the other hand, in the acquisition price, standardize the company's integrity, especially small workshops.

Blue Valley Wisdom (Beijing) Energy Technology Co., Ltd. is one of the white list companies belonging to the tradder.

Wang Xiaopeng, director of the company's energy integration, introduced that the current power lithium-ion battery recovery price is chaotic, and regulates that the company is in a disadvantage. In addition, the current dynamic lithium-ion battery specification is more different, mostly single-piece small batch, which makes the company difficult to play scale benefits. Xucheng, member of the National Committee of my country, said that the current recovery of the powerful lithium-ion battery storage and transportation and dismantling cost is higher.

Under the lack of incentive policy support and marketing mechanism, some standardized companies' battery recycling is not high. Non-regulatory companies, especially small workshops to deal with retired dynamic lithium-ion batteries, and low resource recovery rates, the power lithium-ion battery capacity is attenuated to 80% of the rated capacity, but in the face of retirement, it is still possible to carry out , Used for low speed vehicles or energy storage equipment. Xu Yanhua said that the maximum risk of decentralized companies, especially small workshops, is safe.

Some retired dynamic lithium-ion batteries have flowed into small workshops, they are made into small charging treasures, or simply processed a new battery, and even use soil measures to extract precious metals, bring security and environmental double hidden dangers. And regulating the company a lot of effort in terms of safety. Wang Xiaopeng introduced that in order to ensure battery safety operation, Blue Valley intelligence energy has developed a set of battery online monitoring management platform, and instantly monitors the state of each battery through the Internet.

The retired dynamic lithium-ion batteries that cannot be used in the ladder are disassembled, broken, screening, which can be extracted in which the rare metal element regeneration is used. Phase related to lithium iron phosphate ion batteries, some rare metals in three-yuan lithium ion battery high, regenerative utilization benefits, small workshop more inclined to recover ternary lithium-ion batteries. However, the processing of the small workshop on the three-dimensional lithium-ion battery is worrying.

It is understood that the process technology is different, the gap between recovery efficiency is large, the resource recovery efficiency of small workshops, and the refining quality is not high. According to Zhao Xiaoyong, there are currently domestic companies to adopt wet metallurgical processes, using wet metallurgy technology, the total recovery rate of the three-dimensional lithium ion battery is less than 44%, the total recovery rate of the ferric lithium ion battery is less than 28%. And regulating the company adopts other processes, the two batteries can reach more than 90%.

"This is the data of more regular companies, and the small workshop uses manual and simple equipment operation, the recovery rate is lower.". "Zhao Xiaoyong said.

Strengthen the construction of the trace source management platform, improve the recycling traceability management system Xu Zeyi recommended, speed up the construction of the power lithium-ion battery recycling system, and establish a set of traceable, traceable recycling supervision system, realize the power lithium ion battery Cycle supervision. At the same time, it should also establish a recycling system with new energy car companies for responsibility. In recent years, the relevant departments have introduced a series of policy measures such as the construction and operation guidelines for the construction and operation of the new energy vehicle power lithium-ion battery recycling service outlets.

Recently, the "14th Five-Year Plan" "Circular Economic Development Plan" issued by the National Development and Reform Commission has once again proposed that strengthen new energy vehicle power lithium-ion battery traceability management platform construction, improve new energy vehicle power lithium-ion battery recycling traceability management system. "So far, retired dynamic lithium-ion batteries are important from 2015 new energy vehicles. At that time, the total owner was about 500,000.

"Xu Yanhua said, because the overall scale is small, the dynamic lithium-ion battery recovery system, the entrance system is still in the process. However, with the rapid increase in new energy car insurance, many battery production companies have expanded their investment in recycling network, some car production companies or cooperation with battery recycling industry, or announce the self-built closed-loop recycling network. Material Technology Company invests in strengthening the development and promotion of renewable utilization and ladder utilization completion technology equipment.

"Sports is the current new energy field. "Wang Xiaopeng introduces," the car is over, remove the entire battery package, replace the new battery, from the station to the outbound only three or four minutes. "Whether it is a boosting power station, or the battery is replaced, Xu Yanhua believes that the automobile production company can construct a complete life cycle of the power lithium-ion battery, and the powerful lithium-ion battery is returned, and then find a company specializing in recycling.

, Do resource treatment. Xu Yanhua believes that there is currently a record of the dynamic lithium-ion battery when the new energy vehicle is exported, and it is difficult to track the second-hand car part. She suggested that the contents of the powerful lithium-ion battery recovery can be added to the current dual integration policy - the dual integration policy implemented in 2018, through the evaluation of the fuel consumption and new energy vehicles of the automobile production, meet the requirements of reward Not reaching the required punishment.

"You can motivate automobile production companies to find ways through integral mode, and track the power lithium ion battery to the end. Xu Yanhua said. (Originally published on August 2 "People's Daily" 7 edition).
