In the face of the increasing recycling demand of the dynamic lithium-ion battery, this year, my country's two sessions of China will write "power lithium-ion battery recycling" topic to government work report. At the same time, many departments such as the Development and Reform Commission issued the "14th Five-Year Plan" Circular Economic Development Plan, the power lithium-ion battery recovery action is one of the 11 key projects. With the continuous development of automobile intelligence, electric trends, new energy automotive penetration will continue to improve.

In 2020, the sales volume of my country's new energy vehicles was 13.67 million, up 3.9% year-on-year, of which pure electric vehicle sales were 1116,000 units, and the plug-in mixed sales volume was 251,000, and domestic new energy vehicle sales is expected to reach more than 15 million in 2030.

This period will bring a lot of power lithium-ion battery recycling ladder. Dynamic lithium-ion battery ladder: Data Source: First Electric Network, King King Check Power Lithium Ion Battery Recycling System: Trader Utilization and Regeneration Utilization With the number of electric vehicles, the number of lithium ion powered lithium ion batteries The recycling of retired dynamic lithium-ion batteries has become a very solved problem. If you do not recover the abandoned lithium-ion batteries, it will have a serious impact on the natural environment.

And the recovered lithium ion battery is subjected to technical extraction, and many materials can be used for secondary use. The recycling of the dynamic lithium-ion battery is important to the ladder utilization and dismantling recycling and regenerating the two cycling processes, and the recovery cycle of the power lithium ion battery starts from the ladder. Waste dynamic lithium-ion battery recycling: Source: Source: The line is subjected to light scrap, it is important to reduce the battery capacity below 80%, and it is impossible to apply to new energy vehicles, but the battery itself has not been scrapped, and the retired battery can be retired.

Recycling, screening, reuse in other fields, typical applications are energy storage sectors, such as scenery, peaks, spare power, home electrical energy adjustment, etc. Carrying the ladder utilization can alleviate recovery pressure, reduce environmental pollution, improve economic benefits, and help use the development of renewable energy. Regeneration use belongs to severe scrap, the general battery capacity has been serious, and it is impossible to continue to use.

It can only rejuvenate the noble metal such as nickel, cobalt, lithium in the battery. Retired dynamic lithium-ion battery processing method: Source: "Research and application of lithium-ion dynamic lithium-ion battery" Lithium iron ion battery: Lithium iron ion battery: The main force of the ladder is currently using the most powerful lithium ion battery on the car is iron phosphate Lithium-ion battery and ternary material battery. The battery is mostly a lithium iron-free battery, and the lithium iron phosphate ion battery capacity increases slowly attenuated with the number of cycles.

When the battery capacity is attenuated to 80%, the lithium iron ion battery retired from the car is still available. More cycles, there is a higher ladder utilization value. The lithium phosphate ion battery cycle life is more than 3,500 times, and the part can reach 5000 times, and the capacity is slow to increase the increasing attenuation trend.

In addition, iron phosphate ion battery is free of cobalt, lithium, nickel, and low resource value. Therefore, the lithium iron phosphate ion battery will continue to be used as the energy storage battery, and the three-yuan battery can be refined with metal such as nickel, cobalt, lithium, more suitable for resource recovery. According to the service life of the power lithium ion battery 4-6 years, it is speculated that by 2022, iron phosphate ion batteries will be the main force of retired batteries.

Dynamic lithium-ion battery ladder utilization section: Source: "Research on Dynamic Lithium Battery Ladder", traveling of dynamic lithium-ion battery ladders Using important applications from the application area, retiring dynamic lithium-ion battery ladder can be used as storage Can material material, perform valley, smooth distributed power supply fluctuations; can also be used as a backup power supply for communication base; or with a relatively low performance of battery performance in low-speed electric vehicles, electric motorcycles, etc. The retired dynamic lithium-ion battery has huge application potential in the fields of energy storage and low-speed electric vehicles. The energy storage scenario is not high, and the energy storage system can use the battery using the battery in the range of 20% -80% of the residual capacity interval, and the wide range can improve the economics.

Dynamic lithium-ion battery ladder useful energy storage system: Source: Integrated Electronic Electric Vehicle power storage battery step by battery to apply to power system energy storage, but due to the difference in performance parameters of the decommissioning power battery cell, how to determine Simple, appropriate, reliable and have a certain sorting condition for a certain uniformity is the technical problem that needs to be solved. From the entire application level, the current is currently relatively immature due to lack of industry standards, and there is still a safety problem in the utilization process. After different types of battery recovery, there is still difficult period, and the ladder is still in exemplary.

Application phase. Recently, the National Energy Administration issued "new storage project management specifications (provisional)". It is pointed out that the new powerful lithium-ion battery ladder is used to use the energy storage project.

It must follow the full life cycle concept, establish battery consistency management and traceability system, and the ladder will use the battery to obtain the safety assessment report issued by the corresponding qualification agency. Dynamic lithium-ion battery ladder utilization scenario: Source: GGII, Bnef power lithium-ion battery step Utilization market pattern is actively carried out in active research on dynamic lithium-ion batteries. Germany, the United States, Japan, etc.

start early, has successful demonstration engineering and business projects. Japan 4Renergy, Sharp, Tesla, US Tesra, has been used in personal or commercial energy storage projects. The domestic ladder has gradually taken the commercialization, and the newly transported ladder uses the energy storage project in the past two years.

It is concentrated in the industrial and commercial storage capacity, and the region is concentrated in Jiangsu. The 1MW / 7MWH ladder used in Jiangsu Ruidong is a first commercial operation attempt to be domestic company. It is approximately 4,500 from Zhongheng Pu Rui Jie Jie Jie.

Yuan / Peak Gallery. Cascade utilization technology barriers, discrete integration technology, BMS, and life prediction technology, but also establish energy storage, low-speed battery sales channels, relative to third-party company's power lithium-ion battery factories or vehicle advantages. Under the current dynamic lithium-ion battery retirement, the major powered lithium-ion battery recycling manufacturers have active, accelerate running horses.

Dynamic lithium-ion battery recycling and new energy vehicles two related industries head companies are bound to each other, layout dynamic lithium-ion battery recycling market, seeking fast, market, grasp the opportunity. In the face of the unlimited Blue Sea market, the participants in the battery recovery are more and more, leading companies can be divided into two categories: third-party resource recycling company, and new energy automobile industry chain of the whole vehicle, materials, batteries, etc. Guanghua Technology, Tianqi Shares, etc.

Third-party recycling company is the forerunner of this track. Lithium-electric material suppliers are actively participating, the first batch of batteries released by the Ministry of Industry and Information Technology include Greenmeal, Huayou Cobalt and Xiamen Tungsten, Zhongwei Shares and Zhou Lithium Lithium Industry and other companies are also the first field. Ningde Times, BYD, Guoxuan High-class battery supplier, and the entire vehicle factory, which is like, etc.

, also actively layout. In Ningde Times, in 2015, Ningde has acquired Bangp circle, and produces three-dimensional positive precursor by recovering metal elements in used battery. The business business of Ningde, Ningde, which has also included battery recovery systems.

BYD has established more than 40 dynamic lithium-ion battery recovery outlets worldwide; as a company, BYD has invested in the Ningde Times, Guotai Junan and other companies to invest in battery assets "We can", the goal is not just to do recycling, but to do the full life of the battery. Cycle management. In the future, with the performance of the battery, the value of the tradder will also be more and more, there will be more vehicle factory and battery factory to invest in this area, thereby spreading the cost of full life.

From the main body of the layout, the upper and downstream companies such as resources, materials, battery new energy vehicles are actively carrying out the layout of regeneration, and the third party's resource recycling company has involved. With the climax of the power lithium-ion battery, each company's investment and construction factories and capital acquisitions are gradually intensive. Due to the dynamic lithium-ion battery recovery responsibility mechanism, and the systematic complexity of battery recycling, the strategic alliance in the industry chain downstream is an inevitable trend in the future.

Dynamic lithium-ion batteries have so far, different manufacturers' batteries have a lower consistency, and the power lithium-ion battery is different from the energy storage battery technology standard. Some decommissioning batteries may not meet the requirements of the energy storage battery, and the battery capacity, voltage, internal resistance. When the step is used, it will form a fell in the number of cycles, which causes great difficulties in the later use maintenance.

Overall, my country's retired dynamic lithium-ion battery is still in the pilot stage. Considering the life cycle of the power lithium-ion battery, the direct report of the direct reported volume of the domestic lithium-powered lithium-ion battery has not until the outbreak period, and the source of waste battery is still based on the production of waste and electronic consumer lithium-ion batteries in the battery factory. At present, there is no professional battery recycling network, and it is important to rely on the similar methods of waste items to carry out the lithium-ion battery, causing environmental pollution, and emphasizing the production of electric vehicles and powered lithium-ion battery production companies will undertake the recycling network.

Construction, gradually realizing systemization. .
