Yixinfeng-On the recovery of power batteries by Japanese car companies
On September 4, local time, the Japan Automobile Manufacturers Association announced at its monthly regular meeting with the Ministry of Economy, Trade and Industry of Japan that Toyota, Nissan and other Japanese automakers will jointly launch a project in October to recycle lithium from retired electric vehicles. Ion battery. As electric vehicles become more and more popular, the recycling and reuse of retired batteries has also become a serious social problem. Japanese automakers, which have always been keen on "grouping and heating", are no exception this time. They hope to work together to establish an effective recycling system for used batteries, reduce the cost of power battery recycling, and achieve sustainable development.(High Speed Slitting Machine)
■ Proceed to the end of the "group" It is reported that the retired battery recycling project will be operated by the Japan Automobile Recycling Cooperation Agency, which is a joint venture funded by a number of Japanese car manufacturers and is headquartered in Tokyo. The project will initially set up factories in seven prefectures in Japan, namely Hokkaido, Akita, Ibaraki, Aichi, Okayama, Hiroshima, and Yamaguchi. Later, more battery recycling facilities will be established nationwide. In addition to automakers, the project will also be open to Japanese import car dealers and electric car start-ups. The Japan Automobile Manufacturers Association hopes to establish a recycling model for decommissioned lithium batteries covering the entire industry. So, how does the project work? After receiving the used electric vehicles, the car disassembly outlets will disassemble the decommissioned batteries, and then transfer them to the recycling factory mentioned above for processing. Automobile manufacturers need to pay a certain processing fee to the Japan Automobile Recycling Cooperation Agency. At present, the warranty period of electric vehicle power batteries provided by mainstream automobile manufacturers on the market is generally 5 to 8 years. In other words, the first batch of electric vehicles on the market has begun to enter the replacement period, and the peak period of lithium-ion battery scrap is about to come. Nissan’s first-generation Leaf pure electric vehicle was launched in 2010, and the Toyota Hybrid Prius α, which was launched in 2011, both use lithium-ion power batteries. Relevant agencies predict that the number of lithium-ion batteries that need to be recycled in Japan will increase to 500,000 sets by 2025. With the advent of the era of electric vehicles, the recycling and reuse of waste power batteries has become an important prerequisite for the sustainable development of the automotive society. To this end, the Japanese automobile industry has begun to take precautions and take the initiative. Recently, the Japanese automobile industry has been particularly active in the development of electric vehicles, and has repeatedly combined the strength of the entire industry to develop advanced and key technologies. For example, Japan's New Energy Industry Technology Development Organization (NEDO) announced in June this year that it would spend 10 billion yen to develop solid-state batteries. Its members include 23 vehicle and battery and material manufacturers, as well as 15 universities and public research institutions. In July this year, the Japanese Ministry of Industry stated that Japanese car companies plan to establish a joint procurement organization to ensure the supply of cobalt, an important raw material for lithium-ion batteries for electric vehicles.
■ Broad prospects for secondary utilization At present, there are two main recycling modes for power batteries: one is cascade utilization. The cascade utilization is slightly scrapped and can be used for secondary utilization in energy storage equipment and low-speed electric vehicles; the second is recycling. After the disassembly, the raw materials of the lithium battery are re-extracted for battery remanufacturing. After the electric vehicle power battery is retired, the potential for secondary utilization is huge. In fact, when the power battery is decommissioned, its battery capacity retention rate is still as high as 70% to 80% of the initial value. More and more companies are beginning to recycle decommissioned batteries and use them in static energy storage equipment.
