Power battery "Recycling Hot" Global Transmission

As the number of electric vehicles continues to increase, the number of batteries is constantly increasing, and people have begun to worry about how such lithium-ion batteries are used in 10 to 15 years. Why will recycling will cause people to care? The first is cost: Because the electric car battery is complex, it is made of rare metals such as cobalt and manganese, and it is one of the most expensive parts in such cars. As electric vehicles become more common, recover such metals from waste batteries, which is much cheaper than from earth.

More importantly, it can reduce carbon footprints, not only to reduce carbon footprints that occur when driving, but also strictly control the battery's recycle during battery raw materials to abandon the entire life. South Korea established the first dynamic lithium-ion battery recycling company reported that EarthTech can disassemble 5,000 electric vehicles every year to handle 2000 tons of waste electric vehicle batteries. In addition, EarthTech also said it will invest 24 billion won (about 20 million US dollars) to build the company, and the first facility.

In this plant, the disassembled battery will first accept performance test, then prepare for fixed energy storage systems according to their own conditions and remaining capacity. If the test indicates that the battery has no reuse, the raw materials such as lithium, nickel, cobalt and other valuable metals in the battery in the battery in the battery are also recycled. Earthtech has not yet determined the recovery rate of each recyclable material in the battery.

In addition, the company also conducts research and business projects of various electric vehicle batteries. The business of recycling batteries from electric vehicles is constrained by complex environmental conditions. In addition, it is difficult to obtain technology and technology for recycling waste batteries.

EarthTech will store all scrapped electric vehicles in the room and remove the battery through environmental protection methods. The public launched two solutions to the Volkswagen planned to produce one million electric vehicles in 2025, and have begun to study how to reuse batteries in such electric vehicles. In order to solve such challenges, the public is using two ways to recycle batteries, one is to launch portable charging piles, one energy-saving recycling.

Old lithium ion batteries that have been used for electric vehicles for 10 years or more, may not be suitable for automotive supply, but they still have considerable energy capacity. (2019 Volkswagen E-Golf model battery pack can store energy, with US family a day, even longer useful energy. ) Electric cars should be charged in many places, and this place may not charge piles, or even without charging station.

First, mobile charging treasure These two questions can be solved only by one solution. Volkswagen Group plans to produce a portable fast charging pile, such charging piles can store 360 ​​kWh energy, up to 4 cars charging at a time, the maximum fast charge output power is 100 kW. As with the portable mobile phone charger, the Charging pile of the mass group can be used until the power is exhausted, or to connect the power to the charge.

In addition, the charging pile is small, and it is difficult to deploy a place to charge in the music festival. The battery pack used by the charging pile is the same as the electric vehicle produced by the mass MEB platform. In this way, when the life of the electric vehicle battery pack reaches the limit, it is also useful as a battery of the charging pile.

The first portable fast charging pile of the Volkswagen Group is expected to be installed in Germany next year, and the Volkswagen Group is expected to fully produce the charging pile in 2020. Second, recycling battery materials If all batteries have lost storage energy, the Salzgitter component plant will use. The factory is expected to become the first electric vehicle battery recovery center.

Next year, the end of the Salzkit Factory will reach 1200 tons, about 3,000 electric vehicles. Volkswagen will use a special broken battery machine, a single battery component will be grinded, and the liquid electrolyte will be removed, and such battery components will be broken down into "black powder", including valuable cobalt, lithium, manganese and nickel. Such raw materials, and such feedstocks are further physically separated, and then they can be reused in new batteries.

The long-term goal of the public is that it is hoped that about 97% of the scrap electric vehicle (EV) medium battery pack raw materials. Now, the recovery rate of the Material raw material is 53%. Salzkit Factory is expected to make the recovery rate of the mass battery raw materials to 72%.

Volkswagen expects to have more battery recycling plants similar to Salzkit Factory in the next few years. Considering the sales volume of the Volkswagen Electric Motor Plan, the public will take the battery recovery in the company within the company, although it is currently at least 10 years of processing battery in the company's internal treatment of battery recovery. According to foreign media reports, Earthtech will become a company in South Korea to enter electric vehicle battery recycling business.

The company has built a professional facility for disassembling electric vehicles and recycling waste batteries. Tesla is expected to save a large number of battery material funds in the development of a large number of battery materials. In addition to the public, as an electric car open, Tesla is also developing a "unique battery recycling system", the company believes that Long-term perspective, the system can save "considerable funds".

On April 15th, Tesla announced a new "IMPACTREPORT), the report shows that the Tesla team has more than 500,000 electric cars to help prevent 4 million tons of carbon dioxide is discharged. Atmosphere. In this report, Tesla also expounded the idea of ​​recycling of batteries: "I often hear someone asking," How do you deal with the battery pack of Tesla? ".

Fossil fuel and lithium ion batteries are energy, but the difference between them can be extracted and used in one time, while the material in the lithium ion battery can be recovered and reused. When the oil explorates from the ground, after chemical refining and burning, it will release harmful gases to the atmosphere, and such gases cannot recover and reuse. In contrast, the battery material is refined, and then put it into the battery, it can still be retained after the battery life is finally reserved, and the valuable material can be recovered.

". In terms of battery recycling, most car manufacturers currently focus on the application after the battery pack life is exhausted, and Tesla is different from them. Mechanic manufacturers such as modern, BMW and Renault have announced that they will use old battery packs in the energy storage system, rather than recycling battery packs to produce new battery packs, some of which have been using recycled old battery packs for use in Energy storage system.

Tesra said that due to the life expectancy of the battery pack, there is currently not recycling a large number of battery packs, but Tesla is reclaiming several battery packs for "R & D, production, quality control and service operation". The company said it is working with third-party battery recovers around the world to handle all used batteries, recover valuable metals. Work with recycling partners to ensure that materials do not have value or unrecoverable in the battery.

But this is obviously just a temporary solution, because Tesla said it is still in the No. 1 Super Factory (GigaFactory1), Nevada (GigaFactory1). Tesla said in the report: "Tesla is developing a unique battery recovery system at Super Factory No.

1, which can handle battery production waste, and can handle scrapped batteries. Through the system, the recovery rate of all metals such as copper, aluminum and steel, etc., such as lithium, and cobalt, etc.

will reach the highest. All of the above materials will be recovered in the form of the most suitable for new battery production materials. At present, several companies are studying how to recover key minerals from the battery during the recovery process.

Recently, AmericanMangnese has achieved high recovery rates in the pilot recycling factory.
