Xinhua Finance Tianjin September 28 (Reporter Li Ting, Wang Ning) With the rapid development of my country's new energy vehicle, the power lithium-ion battery ushered in the retired tide, producers' responsibility extension into the recycling of dynamic lithium-ion battery Important measures for network. However, the reporter surveyed, although the automotive production company should undertake the main responsibility of the battery recovery, some companies reflect "producer said it is not considered". The industry experts believe that this dilemma is important that the recycling system of the dynamic lithium-ion battery is still imperfect.

From the top design, industrial ecology, technological advancement, etc. - Who is responsible for the power lithium-ion battery recovery? As new energy vehicles accelerate into the market, the retire of dynamic lithium-ion batteries is also gradually approaching. my country's automotive technology research center data show that my country's power lithium-ion battery accumulates about 200,000 tons, and has increased year by year.

It is expected that the amount of revenue will reach 780,000 tons in 2025. In the face of the upcoming massive power lithium ion battery recycling requirements, "Who will receive, how to collect" once become the focus of the industry discussion. In order to promote the recycling of power lithium ion batteries, the establishment of producer responsibility extension becomes an important measure of dynamic lithium-ion battery recovery.

In 2018, the "Interim Measures for the Recycling Management of New Energy Automobile Power Battery Battery" issued by the Ministry of Industry and Information Technology, it will implement the manufacturer's responsibility extension system, and the automobile production company undertakes the main responsibility of the power storage battery recycling. Perform the corresponding responsibility, protect the effective utilization and environmental disposal of the power battery. In order to implement the requirements of the production person's responsibility, Tianjin Yinlong New Energy Co.

, Ltd. has established a dynamic lithium-ion battery ladder and has entered the Ministry of Industry and Information Technology "New Energy Automobile Waste Battery Comprehensive Utilization Industry Standard Conditions". (Second batch) (referred to as white listing company).

Recycling retired dynamic lithium ion battery pack After the detection of appearance, voltage, consistency, dismantling the battery cell, ultimately use the base station, street lamp and other ladders using application scenarios. In addition to the vehicle factory, the battery factory self-built dynamic lithium-ion battery recycling network, and the third party integrated recycling company cooperation to build a recycling network has become an important direction, driving the development of third-party comprehensive recycling services companies. Tianjin Saidimei New Energy Technology Co.

, Ltd. is an important part of the retired dynamic lithium-ion battery, and has established recycling service networks with battery factories, vehicle products and other cooperation. Recycled dynamic lithium-ion batteries After the equipment is treated, various materials such as graphite, copper, aluminum, etc.

"Repair the separated scrapped negative electrode material as a good positive and negative material, can return to the battery production section, producing a battery that is relatively low in energy density. "Zhao Xiaoyong, general manager of the company. Zhao Xiaoyong revealed that the number of recycling of the company's dynamic lithium-ion battery has increased significantly.

In the first half of this year, he has completed the recovery of last year. "On the one hand, the number of retired batteries in the market is new. On the other hand, the company's channel capacity is continuously enhanced.

At present, more than 140 comprehensive recycling service outlets have been established. It is expected that the comprehensive recycling service outlet can reach 200. "-" Producers said that it is not considered "The recycling of the dynamic lithium-ion battery in the back industry is important including the ladder utilization and regeneration.

The ladder is used in the field of high storage, low-speed electric vehicles, etc .; regenerative utilization is to recover lithium, cobalt, nickel, etc. from waste batteries by wet metallurgy or "physical dismantling + repair".

Metal, resource utilization. The broad market prospects and the reality requirements of the industry's low-carbon development have mobilized the enthusiasm of the parties, but the reporter surveyed, although the state requires the implementation of the production person's responsibility to extend the system, "producers said it is not considered". Industry insiders vomiting, most of the owners have been selling power lithium-ion batteries.

In particular, the battery that has been on the bus before 2018, the source of traceability, a large number of retired batteries finally flows to the non-regular company, is illegally disassembled or fostered in the ladder, which not only has a safety hazard, but also leads to a low comprehensive utilization rate, which is easy to cause Environmental pollution. "After the new energy car is sold, the property rights belong to the owner, the car factory cannot make mandatory requirements, the owner is considered for economic interests, naturally choose high buyers. Relative qualifications, small workshops, individual households, laborers' protection costs are low, high-priced purchase of retired batteries still have to earn, regular companies have no competitive advantage in the market, leading to inferior coins.

Guo Jie, general manager of Beijing Yuanbao Technology Co., Ltd. "Can't receive the goods" also means that the company cannot achieve scale processing, restrictive lithium-ion battery recycling company technology improvement enthusiasm.

The relevant person in charge of a battery production company said that it is difficult to form a single model battery to form a standardization, automation, and intelligent process during the recovery process of dynamic lithium-ion battery. Many industry insiders pointed out that the development of the dynamic lithium-ion battery recycling market is still needed. "According to the life of the company's factory-factory titanate ion battery, it is expected that we will usher in the first batch of officially retired dynamic lithium-ion batteries in 2022 - 2023.

"Tianjin Yinlong New Energy Co., Ltd. said the person in charge, the ladder is based on a large number of large-scale recycling, in order to screen the battery of the comparison of performance indicators for the ladder, if it is unable to obtain a stable supply source, If you can't stabilize the customer's mass supply, you can't achieve your profitability.

- Accelerate the construction of benign recycling industry ecological power lithium-ion battery recycling industry chain longer, forming a benign ecological need to fully standardize. Industry instructor suggests that the government, the company needs multiple parties, from the recycling network, technology research and development, ecosystems, etc., construct a perfect dynamic lithium-ion battery recycling system, promote industry sustainable development.

First, further standardize the recycling behavior, implement the production of the responsible extension system, and increase the prize punishment. "With the increase of whitening companies, the situation of illegal recovery of dismantling is improved. For example, some companies have treated retired batteries through bidding.

As long as there is a business license, they can participate, but this year has added a new list of white listing companies. "Zhao Xiaoyong said. Recently, the Hangzhou Energy Industry Association announced a joint statement, participating in the joint statement for nine new energy vehicles and battery production companies, statement called for the waste power storage battery, restricted the qualifications of bidding companies, bidding companies must be announced Normative comprehensive utilization company, eliminate intermediaries, small workshop companies participate in bidding.

Guo Jie suggested that the public can improve the recovery of waste batteries through deposit systems and publicity and education, and guide them to participate in the powerful lithium-ion battery recycling. Second, improve the sustainability of the recycling of power lithium-ion battery. Guo Jie believes that the most important industry development is in terms of technology, and improves the power lithium-ion battery dismantling efficiency through technological innovation.

"It is competitive with the small workshop, and the regular company is competitive, but the efficiency is improved by technological innovation. It should be fully mobilized, and all kinds of main organizations such as social resources, college experts, and companies should be fully protected and give research rewards. Develop a dynamic lithium-ion battery cell, module, battery pack automation dismantling technology, improve dismantling efficiency, forming sustainable circular economy development model.

"Guo Jie said. Finally, build a dynamic lithium-ion battery recovery utilization benign ecosystem. Experts suggest that the labor, transportation, storage, etc.

Solution, consistency, safety and economy of detection links. Make full use of information from the Internet of Things, large data, build scale, high-efficiency, traceable waste power lithium-ion battery recycling management system, expand the power lithium-ion battery recycling channel. .
