I remember that when I was very small, my parents told me that the battery did not throw it, otherwise it will cause pollution. Today, new energy vehicles have faced the recovery of "retired" batteries, all in Chinese. I remember a retired new energy expert told me: Since you have benefited or use the battery, you must have a responsibility of subsequent environmental protection and re-use issues.

"The words of old experts means deep. There is such a set of data to share with you. According to experts in the relevant industry, the retirement of the dynamic lithium-ion battery after 2018 will arrive, and it is expected that it will exceed 200,000 tons (24.

6GWH) in 2020, a weight of about 20 The mobile phone battery can pollute 1 square kilometers of land for more than 50 years. You can calculate these 200,000 tons of false if there is no effective recycling, what threats will be made to the environment! Specifically, if the lithium-ion battery does not receive effective recovery, nickel, cobalt, manganese, lithium, etc. will cause serious pollution to the environment, water, etc.

; the carbon, graphite, etc. in the negative electrode material can cause dust pollution; the electrolyte can cause Fluorofluorine. According to the universal consensus of the market, there are 70-80% of the battery from the pure electric car, which can be used to accommodate, low-speed vehicles, photovoltaic, etc.

, until 20% of the following is the true scrapping stage. Therefore, the step utilization is the most important way to pay at this stage. The Ningde Times has done such a measurement, and the lithium iron phosphate dynamic lithium-ion battery after retiring can be used as a battery cell for at least 5 years.

When it is directly scrapped and disassembles the recovery, 1 ton of lithium iron phosphate recycling economic benefits are around 10,000 yuan. If used as a ladder utilization income is 3 to 4 times the former, for example, for energy storage power stations, communication base stations, etc. As a three-dimensional lithium ion battery, since the cycle life is relatively short, it is very suitable for disassembly recovery, the recovery price is 40,000 yuan / ton, and the Ningde Times will be dismantled with the nickel-cobalt manganese of the three yuan lithium-ion battery.

The precursor of the metallic material, the price can even reach 80,000 yuan / ton. Even in the future market style, there is no policy support. In January of this year, 16 of my country Tower Company signed a new energy vehicle power battery recycling strategic partner agreement.

In fact, in 2015, my country Tower Company began building a retired battery ladder using the test site. At present, the scope of the pilot has been expanded to 12 provinces and cities, including more than 3,000 experimental sites, covering the preparation, peak, and microgrid, etc. Use conditions.

It has been transferred until February, the Ministry of Industry and Information Technology, the Ministry of Science and Technology, Ministry of Environment, Ministry of Communications, the Ministry of Commerce, Quality Supervision, Sports Bureau, and Energy Administration issued the "Interim Measures for the Administration of New Energy Automobile Dynamic Battery Recycling Management" to encourage automobile production companies, battery production companies. , Scrapped car recycling dismantling company and comprehensive utilization company, etc. Of course, the state's policy is far more than this, and it will be described here.

Regardless of car companies or battery manufacturers, the responsibility is significant, the opportunity is also very large, this theory is applicable to the world, such as the following cases, which make mature episodes for future battery recycling! my country's BYD is not only a car manufacturer, but also a battery manufacturer, so the work of battery recovery belongs. In BYD's entire battery recycling business, the dealer's role is important, they will return the battery to the factory, the factory has been detected whether it can be reused, if it is not, the battery will be disassembled by wet recycling. In addition to the recovery of the battery material, the electrolyte is also an important object of recycling.

The electrolytic solution related to volatilization is light degraded by the exhaust emission system, degrades to normal gas. All in all, BYD's recycling system is also relatively complete, efficient is also high. In addition, BYD is also seeking more battery cladding utilization.

In June this year, BYD announced that the BYD announced the British 18MW container energy storage project. This is the third order that is signed in the UK market after 43MW, 50MW energy storage project. It is reported that the project will use BYD 1.

26MW / 1.26MWH and 0.63MW / 0.

63MWH standard container system, the source of energy is a waste battery, which also reflects the international concern about BYD battery. Beiqi and the way to use the way the battery step is not intended, and the power-saving mode is attached, and it is largely stems from the economic development of the battery. According to the official introduction of Beiqi new energy, the new model will realize the use of battery ladder of the private market, and explore the value of the full life cycle of the battery, promote the recyclable energy of energy, improve energy utilization efficiency; Second, new mode adopts unified battery management method More beneficial to battery recycling and follow-up value development, create more business value.

In addition, it is also regarded as the top priority of the power-saving mode, and completed the joint call of the first shift station in May 20 this year, it is planned to build more than 1100 power plants in 2020 in 2020. In March this year, the SAIC Group and Ningde Times New Energy Technology Co., Ltd.

signed a memorandum of strategic cooperation, and the two sides intended to further deepen cooperation. The SAIC Group said that both parties teamed up to create a complete new energy industry chain closed ring, which will not only promote the healthy development of new energy industries, but also promote the construction of national circular economy and ecological civilization with practical actions. In addition, Ningde Times also realizes battery recycling business in the layout subsidiary.

The chairman of Ningde Times has said that the battery recovery cycle is an important measures for the healthy sustainable development of the dynamic lithium-ion battery industry. At present, the dynamic lithium-ion battery industry is in the early days of development, the recovery is relatively small, the future market space is broad, the company has been launched in Guangdong Bangpu company engaged in battery recycling business. Overseas paid early in 2015, Freewire, USA launched an electric car mobile charging station called MOBI.

This mobile charging station is very interesting, a bit similar to the mobile charging truck we know, like a large "charging treasure". The direct current of the charging station comes from the old battery module of Nissan Leaf, the latter is due to the nasal ancestors of electric cars, and the sales of sales have always been high, so the battery that is eliminated will not be less. According to the introduction of Freewire, this mobile charging truck has launched "upgraded version", and the energy storage will increase from the original 48 kWh to 80 kWh, you can continue to run for more than five hours.

On April 20 this year, the mobile charging station conducted practical applications in the center of Ford Mason in the San Francisco area. It is just a night market. The project is in Freewire to give the second life of the old battery.

The owner is also very convenient to use, can be operated by tablet or mobile phone operation, the problem of charging train is occupied. In March this year, Nissan Automobile, Sumitomo Commercial Co., Ltd.

and its joint venture 4Renergy, opened the first factory specializing in electric vehicles lithium-ion battery in Japan. 4Renergy is a company that focuses on an effective and reuse of electric vehicle batteries. It has developed a system that quickly measures the performance of used batteries.

It is to handle batteries collected from Japan. After the battery is recovered, this plant will use them to make renewable batteries, applied to large storage systems, electric forklifts, and residential and commercial energy storage equipment. YOUNICOS, this is a smart energy storage and grid solution provider based on battery technology.

It is leading globally. It has been more than 100 megawatts in more than 20 energy storage projects in 2017. Before the end of this year, Younicos will design and supply the world's largest, state-of-the-art old-based energy storage system, and the 49 mega lithium ion system will fluctuate in power demand in less than one second.

It is reported that Youngos has also completed an upgrade 3MW battery energy storage system installed and commissioned in Alaska Codiak Island last year, making this island only five renewable resources in the United States to reach one of more than 99% city. At the beginning of 2016, BMW and Bosch established a photovoltaic power storage system, which consists of hundreds of dynamic lithium-ion battery waste modules. This project is called "battery2ndlife", translated is also the second life of lithium-ion batteries.

In addition, BMW, Bosch, and Vattenfall set up a league to achieve the project, and the source of this project is from BMW brand electric cars to eliminate batteries. Written in the last: As mentioned above, this is responsibility, but also the opportunity. Frankly, in the initial stage of the development of new energy vehicles, everyone walked a lot of detours.

Nowadays, a large batch of new forces and traditional car companies are continuing. More and more new products are about to land, and the Blue Sea recycled by the power lithium-ion battery will come. We don't care about who can have a big harvest in the dynamic lithium-ion battery, long-term and long-term planning is the key.

It brings the core demand of battery recycling - sustainable environmental protection. I hope that more companies can put down the burden of profits, and lightly load the burden of environmental protection! (Figure / Wen Netcom Zhang Yupeng).
