Recently, my country's Automotive Industry Association announced the latest data. Data show that from January to October this year, my country's new energy vehicle production and sales is 2566,000, 25.42 million, with a cumulative sales permeability of 12.

1%. Under dual-carbon objectives, the new energy car will carry out two powerful transcripts of production and sales, in fact, it is also facing a "big test" of recycling and treatment of waste dynamic lithium-ion batteries. At present, the power lithium-ion battery equipped with the new energy car put into the market in my country is facing "retire" critical period, and the total amount of retired retirement is about 200,000 tons in 2020.

How to do a good job in the recovery of retired batteries and the recycling efficiency of resources, thereby preventing "blocking points" in the recycling industry chain in the power lithium-ion battery, has become an important task for the development of new energy automotive industries. Circulating use is imminent, due to the metal elements such as lithium, cobalt, manganese in the dynamic lithium ion battery, which will threaten public safety after a large amount of retired battery will threaten public safety, causing difficult environmental pollution, waste valuable price metal resources. The life of the power lithium-ion battery is 4 ~ 6 years.

In 2021, my country will usher in the first batch of powerful lithium-ion battery retirement period. It is estimated that by 2025, my country's powered lithium-ion battery accumulated retirement will reach about 800,000 tons. With such a huge volume, what will the dynamic lithium-ion battery after retiring? The retired road of the power lithium-ion battery is not simple.

Specifically, the recycling and recycling of the power lithium-ion battery can be divided into battery recovery, ladder utilization and regeneration use of these three parts / stages. Zhen lithium research is a production research consultant company specializing in the research and analysis of lithium battery chain market. In an interview with a reporter, Liu Caiheng, a Zhen Lithium Study analyst, said to the "my country Electronics" reporter, the recovery of the dynamic lithium-ion battery is premise and foundation, if you can't recover the battery efficiently, you cannot safely and efficiently.

Ladder use and regenerative utilization. After the recycling, the retired dynamic lithium-ion battery needs to enter the ladder and regenerate utilization from the actual situation in accordance with the actual situation. The reporter learned that "the ladder utilization" is actually reused by the battery, with high security requirements and technical barriers.

After testing, only those energy levels, cycle life, and health conditions can meet the needs of low-speed vehicles, etc., can enter the ladder utilization. "Regeneration utilization" is to disassemble the waste battery, through various physical and chemical methods, extracting and recycling therefrom) Link.

In addition to the requirements for security and technology, the link also involves environmental protection and resource savings requirements. Although the recovery and circular utilization process of retired dynamic lithium-ion batteries is more complicated, the urgency and necessity of this work are undoubtedly. In order to standardize the recycling path of the power lithium-ion battery, in 2018, the Ministry of Industry and Information Technology has announced two batchs of 26 companies to enter the list of "new energy vehicles used to use the comprehensive utilization of industry standards", commonly known as "white list".

As one of the companies "White List", Zhejiang Huayou Circular Technology Co., Ltd. is quite visible in the recovery of retired power storage batteries.

Gao Weiqi, deputy general manager of Zhejiang Huayou Circular Technology Co., Ltd., said to the "my country Electronics" reporter that the non-formal recycling channels of retired power storage batteries and backward recycling methods will cause serious pollution to the environment, and will damage human health.

On the contrary, if the advanced technology is used to recover your precious metals, it will alleviate the exploitation of mineral resources, which can fully excavate and utilize urban mineral resources, which is beneficial to the industrial sustainable and healthy development. Gao Weiqiao also talks about the development of retired power storage batteries, with photovoltaic storage, while doing a good job of retiring power storage battery, can fully excavate the value of the full life cycle of the power lithium-ion battery, and build the environmental protection industry of the whole industry chain. It is conducive to the health and orderly development of new energy automotive industries.

The recycling system needs to improve the upstream mine enterprise (lithium raw materials, manganese ore, cobalt raw materials, nickel mine), intermediate material factory, battery factory (lithium iron phosphate, lithium manganese acid, three yuan lithium, cobaltate) and terminal (with new energy vehicles Mainly constitute a complete lithium-ion battery industry chain. At this stage, my country's dynamic battery recovery field is gradually establishing a joint recovery model for multi-vehicle manufacturers, battery manufacturers, and third-party recovery management companies. Gao Weiqi said to the "my country Electronics" reporter that the current new energy vehicle vehicle company undertakes an important responsibility of the recycling of power storage batteries.

Professional Third Party Recycling Company has gradually established a relatively complete recycling network through a deep partnership with the power storage battery manufacturer and the vehicle manufacturer. But what to see is that the first new energy car battery has just entered the "retired period". Affected by factors such as un maturation of technical treatment and business model, the market system of waste dynamic lithium-ion battery recycling is urgent, to crack many problems.

First of all, technical problems. Gao Wei Que said that the recycling technology of the dynamic lithium-ion battery is complex, involving extensive skills, covers chemistry, engineering, electrochemical, machinery, motor, vehicles, etc., high technology threshold.

In addition, the power lithium-ion battery also has difficulties in the dismantling process, and the production and planning skills of different types of batteries have messy, and it is not easy to dismantle. Secondly, the development and innovation of business models. The power lithium ion battery mainly lithium iron phosphate ion battery contains a small amount of price metal and lower material content, so the recovery benefits are not high; the three-dimensional ion battery contains a large amount of valent metal and materials, and the recovery has good economic benefits.

But it is still short of entering the market, and I have not yet entered the scrap period. How to create a sufficient profitable space in the current market capacity in the current market capacity, this is a "white list" company to think. Finally, the lack of traceability of the power lithium-ion battery during the recovery process.

Liu Caiheng said to the "my country Electronics" reporter that the current industry does not use the traceability of the power lithium-ion battery for recycling links. That is, the full life cycle of the power lithium-ion battery has not formed closed-loop management by tracing source coding system. Due to the lack of market supervision in the recovery link, there is a chaos in the current dynamic lithium-ion battery recovery market.

Co-limited, "White List" is in a disadvantage in the competition with "small workshop". Taking the data in 2018, in 2018, my country's retired dynamic lithium-ion battery has reached 74,000 tons, but the five "white list" companies in the country in that year, only a total of approximately 0.5 million tons of power lithium ion.

Battery, the remaining more than 60,000 tons of power lithium-ion battery is unknown. It is reported that most of these used dynamic lithium-ion batteries flow to companies outside the "white list". "The important issue of the recycling link is that there is no effective channel, and the retired power lithium-ion battery will flow to a company with safety, environmental protection and technical qualifications.

"Liu Cai si said to reporters, on the one hand, this will cause material waste to cause resources due to unable to recover; on the other hand, lithium cobalt nickel and graphite and other substances, and the messy emissions of organic electrolyte will have environmental pollution and destruction. Industrial collaboration is waiting for flowering, although many formal battery recovery management companies have difficult problems with profitability, there has not yet entered a benign development orbit, but the development of anything is not smooth. Under the cooperation efforts of the industry, the recycling and circular utilization of the power lithium-ion battery is gradually growing and mature.

The industry needs to be patient, waiting for flowering. At this stage, the recycling and circular utilization link of the dynamic lithium-ion battery is exploring a blue sea market, providing a new new opportunity for many companies. Input investigation data shows that there are currently 15,000 people in my country's current volatility lithium-ion battery recycling company.

2020 year, my country added 2,579 related companies; in the first half of 2021, 9435 newly registered related companies in my country, the number rose by 2611.2% year-on-year. In addition to the power of new students, all major companies such as Beiqi New Energy, Ningde Times, Beijing Mercedes-Benz also chased this Blue Sea.

In September 2020, Beiqi Penglong, which was established by Beiqi New Energy, Beiqi Futian and other joint ventures, signed a strategic cooperation agreement with Yiguit Group, and established a ladder battery application with smart energy (light, storage, charge) as application scenarios. Demonstration cooperation; in early 2021, Blue Valley wisdom and Beijing Mercedes-Benz formulated a strategic cooperation, and further deepening the new energy car ladder; in April 2021, Yiguete and Ningde Times joint venture established new energy ( Yangzhou) Technology Co., Ltd.

further enhances the core competitiveness in the battery sector. In Gao Weiqiao, the supervision of the relevant departments is a "good medicine" that accelerates the development of the powerful lithium-ion battery recovery and circular utilization. Gaowaco said to the "my country Electronics" reporter, over time, the relevant departments will gradually increase the supervision of the dynamic lithium-ion battery recovery link, and the recycling process will be more standardized, and many of the problems that exist will also Get effective solution.

Liu Yanlong, secretary general of my country's Chemistry and Physical Power Industry Association, made several recommendations to the industry during the interview with "Electronic News" reporter, and hoped that the powerful lithium-ion battery recycling industry entered a benign development track as soon as possible to form industrial cooperation. Liu Yanlong said to the "my country Electronics" reporter, first, car companies must implement responsible people, establish good cooperative relations with relevant professional companies, pay attention to the flow of electric vehicle power lithium-ion batteries; second, to incorporate consumers Regulatory system, guaranteeing the normality of the dynamic lithium-ion battery from the consumer to the market process; Fully grasp the operation of the dynamic lithium-ion battery, value the value of the power lithium ion battery replacement, determine whether the power lithium ion battery can enter the ladder utilization link. .
