Dynamic lithium battery material recovery is 97%, watching the new "ambition"

After the announcement of the investment of 44 billion euros in the next five years, the public recently announced a ambitious plan, and it is necessary to enter the recycling of dynamic lithium-ion battery materials. The short time goal is to achieve 1200 tons of battery materials per year in 2020. Recycle.

The high-worked lithium electrical technology and application learned that the plan will begin with the Salzgitter plant near Braunschweig, the public car announces that a test production line is being built to recover the existing powered lithium-ion battery module. It will reduce its carbon emissions by limiting e-waste and raw materials, while supplying battery materials required for 15 million electric vehicles in the next few years. "Ten years, we have been studying how to restore raw materials.

The most important of these is cobalt, lithium, manganese and nickel, "The Volkswagen Technology Planning Director Thomastiedje said it already has the accumulation of systemic sustainable battery technology, and is further developing. It is understood that the Volkswagen is about to launch the first batch of batteries in the "ID" model series based on MEB platform will be shipped later in this year. The recycling capacity is ready to be completed in 2020, the initial goal is to recover 1200 tons annually.

Material, this is equivalent to 3000 sets of battery systems. Volkswagen expects that the new electric motor type battery will be reused. "Because the scale of the car battery will be very huge, we are more willing to recycle and build their own recycling capacity and system.

" Tiedje said. Volkswagen's long-term goal of recycling of dynamic lithium-ion battery is to recover 97% of raw materials, more than 53% of Volkswagen today. And Salzgitter's new plant will increase this proportion to 72% from now on.

On the recycling path, the EV battery that returns to the public will be evaluated as one of the two ways. The first is "Second Life" option, which can include in the charging station and energy storage area. In large activities, as a spare power supply, it is also possible to apply electric vehicles supply electric vehicles for long-distance travel in a quick charging war deployment.

If you can't choose the second service life, then you will enter the second way, the EV battery will be recycled in Salzgitter. "In this process, individual battery components will be chopped first, then the material will be dry and sieved, then extract'Black powder'This includes valuable cobalt, lithium, manganese and nickel raw materials, will be separated separately, and then available for production of new batteries again. "Volkswagen said, in the entire group, by 2025, its vehicle will have about 150GWH battery capacity per year, which is equivalent to about 50 billion euros of procurement costs.

By selecting a circular economy option, the company means that it will save expensive waste treatment and the cost of purchasing raw materials, so the Salzgitter plant has a cost of costing costs for the public. At the same time, the project also helps Volkswagen from the influence of market and geopolitical factors, such as global lithium demand required to support electric vehicles or increased cobalt mining decreased by producing countries. In fact, with the same way, cost, supply, environmental protection, etc.

Including Toyota, Daimler, BMW, Nissan and other car companies have actual movements in this field in the past few years, and the important way to jointly layout through the cooperation with battery companies and materials companies. (Specifically, please pay attention to the subsequent subsequent report of the high-engineer), if the retired dynamic lithium-ion battery is not properly disposed and the value maximization utilization, it will threaten public safety, causing difficult environmental pollution, and waste valuable price metal resources. Based on this, including my country, the United States, Japan and other countries and regions have also made top design and planning from the policy level.

In our country, in this week, the Ministry of Industry and Information Technology announced the "New Energy Automobile Power Battery Recycling Research Report", in detail, the new energy vehicle and power lithium-ion battery industry, dynamic lithium-ion battery recycling industry development status, and lithium power The status quo of ion battery recovery, the basic status of the ladder utilization and the basic status of the regeneration use. In Japan, in September last year, the Japanese Automaker Association and the Japanese Economic Industry (TRADEANDUSTRY) organized Japanese car companies to initiate a dynamic lithium-ion battery recycling project to establish an efficient and sustainable battery recovery system. Cost is borne by all parties.

A organization called Japanese Automobile Circular Utilization Collaboration (JapanautoreCyClingPartnership) will be responsible for operating joint ventures funded by many car manufacturers. In the United States, the US Department of Energy has launched the first lithium-ion battery recovery center called Recell Center. The goal of the DoE is to reduce the battery cost to $ 80 (about 480 yuan) through the recovery of the battery material.

The center's cooperative participants include universities and research institutions, as well as partners from battery supply chain, including battery manufacturers, car companies, recycling centers, battery lifecycle management services and materials suppliers, etc. The collaborators in the Recell center will focus on four key research areas to achieve a profitable lithium-ion battery recovery, in which the industry is adopted: First, the direct positive recycling, the focus will develop recycling process, there will be directly returned to the new battery Product without expensive processing; Second, the second is to recover other materials, the focus will be the technology that can economically effectively recover other battery materials, thereby supplying additional source of income; third is the recycling design, will develop new battery design, optimization Make future batteries easier to recover; fourth is to develop and utilize modeling and analysis tools to help guide the effective way to develop and verify the work within the center.
