Power lithium-ion battery large-scale retirement is, health and efficient recycling system is imminent. "Accelerating the Construction of the Power Lithium Ion Battery Recycling System" was first included in the 2021 government work report; the "New Energy Automobile Industry Development Plan (2021-2035) issued by the Office of the Office of the Office of the State Council in June 2020" proposes to improve the dynamic lithium ion Battery recycling, ladder use and reinvolutionary circular utilization system, encourage co-construction channels. However, the status quo is not satisfactory.

"The retired power lithium-ion battery in the current stage flows into the informal market through informal channels. The recovery cost and processing cost of formal channels, low economic benefits. With the application of electric vehicles, energy storage, etc.

, if there is no strict supervision in recovery, there will be a lot of problems. "Zhongguancun New Battery Technology Innovation Alliance Secretary General in the Qing Dynasty reminded. The ladder uses urgently to standardize the development.

At present, the retired dynamic lithium-ion battery is important is the two major directions of the ladder and recycling. The former is a domain that disassembles the retired dynamic lithium-ion battery, applied to the field of battery energy density on battery energy density; the latter is the cost of cobalt, nickel in the scrap cell. The dynamic lithium-ion battery performance index of electric vehicles is high, and the battery capacity is attenuated by more than 20%.

It must be retired. Therefore, the power-lithium-ion battery corresponds to different application scenarios: 100% to 80% interval meet electric vehicle power use; 80% To 20% range can be used for ladder use; capacity is less than 20% must be scrapped. According to Eastern Securities, it is expected to reach 37 billion yuan in my country's dynamic lithium-ion battery recycling market by 2025.

Under the goal of "double carbon", the importance of energy storage is increasing. On April 21, the National Development and Reform Commission and the National Energy Bureau jointly announced the "Guidance Opinion" to accelerate the development of new storage (Draft) ", by 2025, realizing the new storage capacity from the initial period of commercialization The large-scale development is transformed, the installed scale reached more than 30 million kilowatts. At the same time, the amount of power lithium-ion battery is incremented year by year.

my country's automotive technology research center data shows that in 2020, my country's powered lithium-ion battery has a total retirement amount of about 200,000 tons. The accumulated retirement amount is expected to approximately 780,000 tons in 2025. If the power lithium-ion battery loader is calculated from the current electric vehicle 50 to 70 kW, 30 million kilowatts correspond to the retired power lithium-ion battery of 600,000 electric vehicles.

In this context, a batch of power lithium-ion battery ladder is used to use the energy storage project. "Many shipped (ladder utilization) projects are exemplary projects that do not count costs, unpacking the battery, high cost. Performance indicators are different, consistency is not guaranteed, there is a certain safety hazard.

"One energy storage industry. Due to management, the system is not yet perfect, the power lithium-ion battery ladder is currently facing certain limitations. Recently, the National Energy Administration Comprehensive Division has publicly requested opinions on the "Novel Energy Storage Project Management Specification (Suggestions)".

"Draft for the comments" proposed, the key breakthrough in battery consistency management technology, the performance monitoring and evaluation system of the power lithium-ion battery, in principle, in principle, in principle, the storage project will not be created in principle. The dynamic lithium-ion battery ladder that has been built has been built should regularly evaluate battery performance, strengthen monitoring, and strengthen supervision. In addition, the relevant units of new energy storage projects should strictly perform the management procedures such as project safety, fire protection, environmental protection, and implement safety responsibilities in accordance with relevant laws, regulations and technical specifications.

"Some regions have been used in some areas. In addition to safety hazards, there is still a phenomenon in which the ladder uses battery and new battery price. At this time, the new large-scale power lithium-ion battery ladder is suspended using energy storage projects, and standardizes energy storage project management.

of. "In the CDC, whether it is battery recovery or development of energy storage, the two markets are in the early days of the development, and the standards of the market are crucial. "Temporary does not mean problems in the industry, how is the key to supervise.

The energy storage is a 10 trillion market in the future, and it cannot deny the entire industry because of certain companies or project issues. "Yu Qing teaches. The recycling and extraction requires a reduction in cost constraint that the lithium iron phosphate ion battery is suitable for the tradder utilization, and the value of the three-dimensional lithium-ion battery recovery is higher.

It is understood that the elemental content of nickel, cobalt, manganese in the ternary dynamic lithium ion battery is high, and when the retired battery enters the recovery process, the metal material such as nickel, cobalt, manganese can be extracted for processing the positive electrode of the battery. Material, effective circulation utilization of resources, current nickel, cobalt, manganese recovery can reach more than 99%. "The dismantling of the three-yuan material is high, while lithium iron phosphate is relatively low because the dismantling of the recovery value is relatively low, and the safety advantages are obvious, more for the ladder.

However, the ladder uses the battery quality. Since this year, my country's Tower has repeatedly released the test of lithium iron phosphate ion battery products. "In the Qing Dynasty, in terms of dynamic lithium-ion battery recovery, there is still no channel in the market, low economic benefits, extensive recovery methods, secondary pollution.

Multi-department has already issued a document to standardize the recycling of dynamic lithium-ion batteries. In 2017, "Automotive Battery Code Rules" announced, so that the power lithium-ion battery coding is ruled. New Energy Automotive National Monitoring and Management Platform and New Energy Automobile National Monitoring and Power Battery Recycling Traceability Integrated Management Platform.

At present, the traceability management platform has been included in information data including more than 560,000 new energy vehicles. It has a total of more than 8.9 million packages, and the battery capacity is over 28 billion watts, involving more than 2,90 car enterprises and more than 180 batteries.

In 2018, the "Interim Measures for the Administration of New Energy Automobile Power Battery" announced by the Ministry of Industry and Information Technology clearly requires that automobile production companies should bear the main responsibility of the power storage battery recycling, and have developed the "White List of the Power Lithium-Ion Battery Recycling Company" 27 companies in the list have strong strength to process the strength of the lithium-ion battery, minimizing environmental pollution. However, there are still many chaos in the field of power lithium-ion battery recovery. Important reason is that the recovery cost and processing costs at this stage have higher economic benefits, facing unqualified, low-cost small workshops, and dealing with regular companies in the use of waste power lithium-ion batteries in the recovery price.

Competitive advantage. "Cooperative host factory is currently limited, important or bidding, but we have no advantage. "Introduction of the staff of a battery treatment company," small workshop can also increase the purchase of batteries from used car owners, we can't.

"However, with the rise and promotion of the" electric electric separation "power transmission mode, new business model or standardization of the dynamic lithium-ion battery recycling market" dawn ". Li Bin, Chairman of the Car, said that "the advantage of" electric separation "is that the car and the battery can be scrapped separately. "If the whole car is scrapped, it is necessary to recover the battery packs that are scattered around the land.

The efficiency is very low; if you separate the scrap, the recovery efficiency will be high. Standardized battery packs have made a good automation based on ladder utilization and recycling. The cost of battery recovery is still a bit high, and the added value of recycling is low.

If the recovery cost is lowered, the recovery efficiency can be enhanced, and it may become a battery production line produced by 'reverse' in the future. ".
