The Swedish energy agency report: global lithium battery recovery than expected China and South Korea have accounted for more than seventy percent

The Swedish energy agency, according to a survey of global rate of lithium ion batteries are far more than expected, China and South Korea has become an emerging leader in lithium battery recycling economy.

lithium ion battery recovery rate was only 5%, this one is often cited data. In fact the statistics the initial study from the friends of the earth, but its report to now have nine years of time, and the data over the years has been the industry reference for many times, even in April 2019 the science magazine nature energy editorial reference.

the survey released this spring to Swedish, and release again in English. Merlin said, there are many misunderstandings for lithium ion battery recycling and misunderstanding. He said that at present the global at present there are more than 70% in the recovery of lithium ion battery is recycled by China and South Korea, far more than often report of 5%.

Melin report claiming that the report data based on the investigation and experience, although it is widely believed that recovery rate is significantly higher than 5%, but for those who understand the global battery industry and the industry battery recyclers, obviously, battery recovery more than 5%. In fact, many companies in China and South Korea have in lithium ion batteries.

in the global scope, have separation and recycling of waste batteries and cathode materials has carried on the preliminary study for more than 300. 70% of the research is conducted by China and South Korea of battery manufacturers, all of the active material ( Including metal lithium) Can all be recycled effectively.

however, most of the research on lithium cobalt oxide ( LCO) Lithium batteries and ternary ( NCM) About batteries, lithium iron phosphate ( 联赛 Battery and lithium manganese oxide ( LMO) Battery research rarely, this means that some commonly used. Has a fixed storage battery types may not be able to completely cover. Melin thinks, because effective recovery process, the future research should pay more attention to how to discarded batteries into the supply chain.

　　“ Battery recycling business in Europe and North America's challenge is how to use the waste batteries, battery recycling prices more attractive because the Asian market, throughout the &; Melin said. “ This is also a main direction of the United States and Europe battery, but now more difficult. Because many Asian battery recycling business was doing business in Europe. ”

牛; The battery in the portable devices need to classify, this can be very time-consuming. Energy storage system for power grid and electric vehicle battery recycling and utilization of need higher levels of skills.

牛; In Sweden's battery application, only about 16% of the battery at the end of its service life is recycling, is far less than 95% of the country's goal. European exports to China or South Korea all kinds of portable electronic devices and batteries, many of them at the end of its working life. The authors of the report, Hans Eric Melin said, & other; The lithium ion battery low recovery does not mean that the global battery recovery rate is very low. ”

牛; Lithium batteries more than 50 companies worldwide. In addition to China and South Korea, other companies are from the European Union, Japan, Canada and the United States.

牛; China has more than 30 companies recycling waste battery and waste. According to the survey, almost all of these companies use technology is wet metallurgy technology, and the production of sulfuric acid cobalt, nickel sulfate or lithium carbonate and other products, some companies are in the use of recycling process sliding battery or NCA battery positive electrode.
