Why is Japanese company to focus on the waste battery of China Electric Motor?

　　Author ：Iflowpower – Portable Power Station Supplier

The retiring power battery of China Electric Motors is becoming the fragrance of Japanese corporate eyes. Recently, many Japanese media reports that Japan Iozhong Commercial Co., Ltd.

has established partnership with BYD. According to the agreement, BYD is responsible for recycling the use of the electric buses, electric taxi and other electric vehicle discharges. After the startup of Shenzhen startup Pandpower, the performance test is charged by itzine.

BYD Electric Bus has developed a large energy storage device in China, which is connected to each other by 160 old powered batteries. It is installed in a 20-foot dedicated container, with a total capacity of about 1000 kWh (kWh), which can be satisfied 100 families need electricity for 1 day, more than 20% -30% compared to the new industrial battery. The unit of energy-saving device developed by Iozin can be used as a factory auxiliary power supply.

It can also be used in photovoltaic and wind power storage. It is expected to be put into production in 2021. Itozhong commercial hopes to reach the battery by recycling the battery in five years, and it is said that if you want to stabilize your profit, you will not leave China and BYD to provide stable sources.

The BYD's power battery has always questioned electric vehicles seemingly environmentally friendly. In fact, the recovery treatment of the battery is not environmentally friendly, this negative view, in fact, from lead-acid. In fact, the lithium power battery life is very long, the average use of the year is 5-8 years, and when its capacity is attenuated to 80% of the rated capacity, it is no longer suitable for electric vehicles, and the retirement will be sown.

However, retirement is not equal to scrapping. Just as the No. 5 battery can "finish the remote control of the toy car", the retired power battery is detected, maintained, reorganized, etc.

, can still be in the energy storage, distributed photovoltaic power generation, home electricity, low-speed electric vehicle and other different scenarios. Realize the use of the ladder. The most common ladder is accommodating.

In 2017, Tesla enabled the world's largest lithium-ion battery system in southern Australia, with a battery array of up to 100 megawatts, which can be charged for 300,000 households. Tesla works with a wind power plant to store the wind power of the power generation period to the battery system, supplemented and stabilized local power supply during peak period, and improved the stability of the local power grid. In 2018, this system saved a local government for $ 40 million.

Although Tesla used a new battery on this system, retired batteries that were recycled on Tesla electric vehicles can also be applied to this scene. In addition to the photovoltaic, wind power storage, retired batteries can also create small energy storage systems for families and merchants in addition to photovoltaic, wind power energy storage. In 2017, Powervault, England, using Renault Zoe and Nissan's retire power battery, built a family photovoltaic storage system.

This system can store redundant photoelectrics produced by solar panels in the owner's home, and access to the municipal power grid, which can be treated with the peak of electricity, reducing the cost of new substation and power delivery equipment, and also improved local grid flexibility. PowerVault's energy storage system is currently using many families and schools in the UK, which can save up to 35% of electricity bills for the owners. Japan's 7-11 convenience store, also used the energy storage equipment built by Toyota Puruis retired battery, one connection fuel cell generator and solar panel, a refrigerator, microwave, sausage, microwave, sausage through the energy management system 7-11 convenience store Equipment and other equipment.

In addition to energy storage, retired power batteries can also provide power for other means of transportation. In 2018, Nissan cooperates with Sumitomi, recycling the old battery in which Nissan is rishes to re-assembles the battery, for electric forklift, golf cart and other low-speed electric vehicles. Nissan Listener and Tesra Models Battery Compare Sweden's EcoSightseeing, recycled the retired batteries on Tesra Models, as the power source of electric drive boat, this boat with boat tours, equipped with battery packs When the capacity is as high as 190 kWh, it can support 14 hour cruise after full charge.

Electric boat and battery position schematic in China, retired battery ladder is mainly concentrated in the field of communication base station. It is not enough to create a new 5G base station. China Tower Company has more than 1.

2.6GWH batteries, which constitutes the maximum demand for power battery ladder every year. As of the end of 2019, China Tower Company has used the battery with more than 4.

5GWH. That is, it is currently available for the power battery of the ladder, temporarily meets the needs of the base station to replace the battery. Taking the lithium iron phosphate power battery as an example, there is still 6 years of service life after the steps of the steps.

Once the battery capacity is less than 20%, it is necessary to scrap disassembly, recovering the metal material in the battery, which is also the most important technical content in the power battery recovery, which is most likely to cause contamination. In the United States Nevada, GigaFactory has a large number of lithium batteries every day, those that cannot pass the board, directly transferred to Redwoodmaterials factory outside the half-hour drive. Tesla Super Battery Factory Production Line Redwoodmaterials was founded by Tesla, founder, and the goal is to become the world's largest battery recycling and battery material company.

Strikebel has always, the power battery dismantling is mainly used in the two ways of fire-making metallurgy and wet mitallurgy. Fire method, is a high-temperature combustion, remove unwanted organics, leave a small number of raw materials such as nickel and cobalt, this process will lose a lot of aluminum and lithium, and the environmental pollution is very serious. Power batteries and various raw material wet metallurgical, mainly for pretreatment of strong acid to power cells, remove the outer casing, exhausted electricity, then immersed the battery in a strong acid solution, and finally purify the leaching solution to obtain a raw material, this method is high, the process is complicated Even more than the direct mining lithium ore is much more expensive.

Redwoodmaterials battery recycling factory and Redwoodmaterials knows that combined with fire method and wet method, innovating a smelting method: first using battery residual electric driving conversion to generate high temperatures, separating battery metal with fire process, then recover the purification by wet process Metal raw materials. Redwoodmaterials battery recycled Smelting Smelle has never revealed the specific recycling details, but he has been claiming to recover nickel, cobalt, copper, aluminum, and more than 80% of lithium in power cells. The LI-CYCLE named North America's largest lithium battery recycler is also innovative.

Li-cycle workers The company puts the scrapped battery into a container that can discharge and chopped, and recovered to different metals through a staging wet process. The company claims that their approach has been able to recover all the power batteries. Transforming into available raw materials, future large-scale lithium battery dismantling recovery will be very convenient.

Electric Vehicle Power Battery According to the statistics of the China Automotive Industry Association, by 2025, the power battery of changing the changing will reach 42GWH, and its scale can meet about 5 million families for 1 day electricity. With the continued investment of old power battery trails and dismantles, the old battery recycling will become a wide range of popular industries in the future.
