Necessity and urgency of recycling of dynamic lithium battery

　　Author ：Iflowpower – Portable Power Station Supplier

First, take a look at the 2016 powerful lithium-ion battery market: According to the latest data, my country's automobile power lithium-ion battery production is 30.8GWh in 2016, up 82% year-on-year. From the technical route, the proportion of the three-yuan dynamic lithium-ion battery in 2016 has risen from 23% in 2015 to 2016.

In addition, with the rapid development of my country's new energy automotive industry, more and more foreign power lithium-ion battery companies have also invested in my country. Samsung SDI, LG chemistry has been put into production in my country Xi'an and Nanjing joint venture, and Panasonic Dalian Factory is under construction, Bosch and SK are also planning to build a plant in my country. The average mileage of private car in my country is approximately 16,000 kilometers.

Under the conditions of the use of private cars, the useful life of pure electric / plug-in cars is around 4 to 6 years; related bus, rental Cars, etc. The power lithium-ion battery production rapidly increases, according to its 5-8 annual use period, it means that my country's powered lithium-ion battery is about to enter a large-scale scrap period. According to industry insiders, the 2018 movement lithium-ion battery recycling market will be out of development, and the market will reach 5 billion.

At that time, my country's powered lithium-ion battery waste recycling market will begin a scale, accumulating the waste-driven lithium-ion battery exceeds 12GWH, more than 1.70,000 tons of scrap, recovered from the recovery market of cobalt, nickel, manganese, lithium, iron and aluminum, etc. The scale will exceed 5.

3 billion yuan. By 2020, my country's car lithium-ion battery will reach 200,000 tons, and market recycling is 10.1 billion yuan.

By 2023, the waste will reach 101GWH, about 1.16 million tons. 2017 market sales are expected to be around 750,000.

Due to less than 2% of my country's battery, a large amount of abandoned battery has caused resource waste and environmental pollution. Reclaiming reason - Environment & Raw material resources limited: Once the electrode material enters the environment, the metal ion, the negative electrode of the battery is in the environment, the strong base and heavy metal ions in the electrolyte, which may cause heavy environmental pollution, including lift soil PH value, poisonous gas may occur properly. As we all know, there is currently a commonly used dynamic lithium-ion battery in the market in the market.

It is important to have two categories of three-dimensional lithium-ion batteries and lithium iron phosphate, including high-quality characteristics due to high energy density. However, the important material of the three-dimensional lithium-ion battery is very limited in China's mineral resources in my country. With the rapid rise in the new energy automotive industry, the demand for heavy metals such as cobalt and nickel is continuously rising, and the import ratio and price are also high in the boat.

Recycling - Cost & Profit points Composition of positive electrodes, negative electrodes, diaphragms, electrolytes such as lithium-ion batteries contain a large amount of price metal. The viable metal components contained in the positive material of different power lithium ion batteries are different, with potential metals with the highest value including cobalt, lithium, nickel, etc. For example, the average content of lithium in the ternary battery is 1.

9%, nickel 12.1%, cobalt 2.3%; in addition, the proportion of copper parts, aluminum moieties is 13.

3% and 12.7%, if it can be reasonably recycled, will become An important source of creating income and costing costs. Due to the rapid volume of electric vehicles, the price of lithium-ion battery is rapidly increased.

At present, battery-grade carbonate prices are from 160,000 to 170,000 yuan per ton, positive material, diaphragm, electrolyte and hexafluorophosphate, etc. appear. At the same time, with the rising rising prices of lithium electric raw materials, lithium battery has had strong economic and urgency, and relevant companies will continue to pay attention to the development of lithium-electric recycling fields, which is expected to form new profit rising points.

Relevant national policies recovered with power lithium-ion batteries: As early as 2006, the Ministry of Industry and Information Technology, the Ministry of Science and Technology and the Ministry of Science and Technology and the Ministry of Environmental Protection of the Ministry of Environmental Protection "Automotive Product Recycling Technical Policy" provisions clearly proposes electric vehicles (including hybrid vehicles, etc.) The production company should be responsible for recycling, dealing with batteries on electric vehicles sold, and requires hazardous waste such as waste batteries to have qualified companies for processing. This is also a notice to the four ministries and commissions of the Ministry of Finance in China, in December 2014, and the Financial Department, etc.

) ", Which clarifies that the car production company as a responsible subject of the power lithium-ion battery recovery, responsible for the recycling of the dynamic lithium-ion battery. In December 2016, the Ministry of Industry and Information Technology has organized the "Interim Measures for the Administration of New Energy Automobile Power Battery Recycling" (Draft for Comment). Clearly encourage the automobile production company, battery production company, recycling dismantling company and comprehensive utilization company, etc.

In the early February 2017, the Ministry of Industry and Information Technology, the Ministry of Commerce, and the Ministry of Science and Technology jointly announced the "Guidance Opinions on Accelerating the Development of Recycling Resources". Utilization of standard system, promoting waste dynamic lithium-ion battery regions. National Policy - Policy Support: Ministry of Industry and Information Technology: Waste Dynamic Lithium Ion Battery Automation Disassembly Equipment will be included in the major environmental technology equipment catalog (2017 version) Ministry of Industry and Information Technology November 14 announced public demand for "national encouragement development major environmental technology equipment The opinions of the catalog (2017 version) "(seeking the opinion), involving 140 major environmental technology equipment.

Among them, the dismantling of the use of waste dynamic lithium-ion battery automation is suitable for comprehensive utilization of waste dynamic lithium-ion battery resources. Key technologies are dynamic lithium-ion battery modules without loss disassembly technology; the final non-metallic waste treatment technology after disassembly; power lithium ion battery monomer mixed feed automatic dismantling technology. Technical indicators: 30 types of monomers / times; monomer processing speed 60s / single; battery end deprotection rate> 97%.

Despite the resilience of new energy automakers, the government is still very supportive for the revenue of the power lithium-ion battery. Shanghai has a reward for car enterprises to recover the dynamic lithium-ion battery, government giving a reward for 1,000 yuan / set; Shenzhen City is subsidized by 50% of the amount of power-based lithium-ion battery recovery according to the audit.
