At the same time in the prosperity of new energy auto industry, the problem of power battery recycling has also become the focus of industry concerns. After recent years, new energy vehicles will be brought about by a large number of retired batteries that cannot be properly recycled and utilized, which not only leads to waste of resources, but also brings environmental pollution. "The establishment of the production responsibility extension system accompanied by the vehicle enterprise, the power battery recycling industry has entered the key period of channel construction.

"Secretary-General of the Ministry of Industry and Information Technology, the Secretary-General of China Electronic Energy Saving Technology Association, Huang Jianzhong, in the seventh automobile power battery recovery and regeneration and secondary battery recycling and regeneration technology seminar, my country's powered battery in April 17 The recycling disposal of design and waste power storage batteries, comprehensive use is currently in the preliminary stage of need to support and regulate development. Industry pain point: high cost, economic weak new energy passenger passengers are usually 5 years, bus and commercial vehicles for 3 years. Before 2022, the retired battery will be based on lithium iron phosphate batteries.

The amount of retaining of the three-yuan battery will be flat with lithium iron phosphate after 2022, and gradually super. The annual retiring volume of the full-year power battery is expected to be 5.14GWH, and the source of retire is mainly new energy passenger cars.

The reporter learned that companies that have been laid out in related business are divided into five categories: traditional recycling enterprises, emerging recycling companies, battery pack factory, battery material enterprises, and vehicle factory. Different types of companies have different advantages and disadvantages. For example, traditional recycling companies have relatively advantages in recycling channels, material regeneration techniques, battery crushing technology, and smelting technology, but due to its lack of power battery sources, they still need to cooperate with the vehicle factory and scrap mill.

The advantages of emerging recycling companies are mainly reflected in battery crushing and dismantling technology. At present, the treatment method of waste power batteries mainly has two types of fire smelting technology and wet smelting technology. Wang Haibei, director of the Metallurgical Research Design Office of Beijing Metallurgy Technology Group Co.

, Ltd., said that the existing smelting process is very complicated and the difficulty is very large. "The smooth operation of the recycling system needs to be premise with profits.

If there is no profit driver, you cannot fully improve your enthusiasm. "Wang Haibei frankly," the investment in the existing recycling technology investment and recycling outlets is very large, although many companies layout test water, but fresh companies dig to large bottles. "It is not to ignore, the battery recovery process will result in toxic electrolyte and harmful gases.

If the improper treatment will bring huge harm to human health. "Some companies use high-temperature heating or combustion in the process, and it is easy to harm the workers' health. "Harbin Baturi Resources Renewable Technology Co.

, Ltd. Ming Yue Bin". Government enterprises seek to break the process for the above issues, the relevant state departments have introduced a series of industry policies to guide and specify the power battery recycling industry.

In February this year, the Ministry of Industry and Information Technology jointly issued the "Interim Measures for the Administration of New Energy Automobile Power Battery Recycling Management", clarifying the main responsibility of the automotive production enterprise. In March, the Ministry of Industry and Information Technology, which jointly issued the "Notice on Organizing the Treatment of New Energy Automobile Power Battery Recycling and Utilization", proposed in the Beijing-Tianjin-Hebei, Yangtze Triangle, Pearl River Delta, Central Region, etc., etc.

Pilot, in the pilot, radiate to the peripheral area. "The issuance of the above notice marks that my country's recycling policy system is gradually completing. "Yang Qingyu believes that" With the continuous breakthrough of related technologies, policy issuance will accelerate, and it is expected that relevant standards will also be released this year.

"The guest considers that the battery type, battery capacity and voltage platform of new energy vehicles are not small. This is the first row of power battery ladder, so how to scientifically assess the decommissioning battery has become a decision battery." Where is the first level?.

"The retired battery evaluation process is mainly to be collected online and offline data, simultaneously uploaded to the monitoring platform, thus analyzing the battery pack, evaluating performance. "Beijing Craft Battery Technology Co., Ltd.

Technology Director Flights. According to reports, after the decommissioning battery is evaluated, the ladder utilization link can be carried out, and the power storage system improves the overall economy, the maximum lithium battery cycle life. There are many exemplary projects that have been used to carry out ladder.

Shanghai Xida New Energy Technology Co. The discharge data shows that there is no attenuation, even lower than the attenuation rate of the new battery. "For the treatment of toxic gases, Ming Yue Bin believes that the pipeline mechanical equipment can be used, and the battery and module are overall.

The overall electrolyte is recovered, and the material is separated from the material, the positive and negative extreme powder, thereby obtaining the final Metal housing. "Since the diaphragm is fully recovered, it will not become a harmful gas. "She added.

In-depth cooperation, industrial chain, it is understood that the power battery recycling system involves a number of stakeholders such as vehicle enterprises, battery manufacturers, battery recycling enterprises, and there are still many difficulties in the chain. In this regard, Xie Shaozhong, general manager of Jiangxi Zhou Circular Technology Co., Ltd.

, gives recommendations: "The various links of the industrial chain need to be worn, but the overall principle should be a professional thing in 'professional people'. For example, the automotive enterprise sets the recycling channel. After the recycling, the comprehensive utilization enterprise is handed over to professional processing, and the industry chain is deeply cooperated.

"It is reported that there are many enterprise layout power battery recycling this Blue Sea: At the end of 2017, Beiqi Xin Energy released the" Optimus Pillar Plan ": By 2022, it is expected that 3,000 yuan will be built in the country. The light storage power storage station, accumulated 500,000 units of electric shipment vehicles, and the ladder storage battery exceeds 5GWH. In January 2018, 16 companies such as China Tower Company and Sander Group signed a new energy vehicle power battery recycling strategic partner agreement.

China Tower will use pure electric bus to retire the power battery, after testing, sorting, and recombination, instead of lead-acid batteries for communication base stations. "Whether it is a vehicle enterprise or a power battery company, it is striving to practice the advanced concept of producer responsibility. I hope that all participants can explore the model, mechanism of power battery recycling of industries, enterprises, product characteristics from the perspective of responsibility for enterprise social responsibility.

"Huang Jianzhong pointed out." If the pen of the power battery is the joining and resource disposal, then the recycling mode, the establishment of the mechanism will be its god. ".
