Waarom is het moeilijk om lithiumbatterijen te recyclen? Blauwe oceaan

Why is it difficult to recycle power lithium batteries? "Blue Ocean"



De opkomst van elektrische voertuigen zorgt voor een nieuwe -honderd-miljard-dollar markt - lithium-energiebatterij-ionbatterijrecycling.




According to data from MarketsandMarkets, the world's second largest market research and consulting company, the global power lithium-ion battery recycling industry is expected to reach US12.2 billion in 2025 and US18.1 billion by 2030. my country is one of the largest power lithium-ion battery recycling markets.




Volgens de analyse van het China Merchants Securities Research Report zal mijn land vanaf 2021 de piekperiode inluiden voor de eerste batch lithium--ionbatterijen die met pensioen gaat.




Nu de ontmantelingsgolf van lithium--ionbatterijen nadert zoals gepland, wordt het lot van lithium--ionbatterijen na ontmanteling een probleem dat niet kan worden genegeerd. Het aantal lithium--ionbatterijen dat buiten gebruik wordt gesteld, is erg groot en als ze niet op de juiste manier worden behandeld, zal dit grote schade toebrengen aan het ecologische milieu.




At present, there are two important recycling methods for retired power lithium-ion batteries. One is to carry out "echelon utilization" of retired power lithium-ion batteries that meet the degree of energy attenuation. Base station backup power or electric bicycles and other fields; the second is to recycle and "recycle" the batteries that cannot be used for "echelon utilization". "Recycling" is mainly to disassemble the battery to extract and recover the precious metal raw materials, such as cobalt and nickel. , manganese, etc.




The ideal mode for the recycling and reuse of power lithium-ion batteries is to "echelon utilization" and then "recycling", but the current method of dismantling and recycling power lithium-ion batteries is still the main method of disposal. There is also a battle between the "regular army" and "small workshop" in the battery recycling arena behind this.




Since 2018, the Ministry of Industry and Information Technology has announced that 26 companies have entered the "white list" that meets the "standard conditions for the comprehensive utilization of waste power batteries for new energy vehicles". Companies that enter the "white list" are considered "regular".




Data in 2018 showed that the total amount of power lithium-ion batteries retired that year reached 74,000 tons, but the first five "whitelist" companies in the country only recycled about 5,000 tons of power lithium-ion batteries in total, and the remaining 6 More than 10,000 tons of power lithium-ion batteries are "unaccounted for".




Judging from the "white list" companies of the Ministry of Industry and Information Technology, the majority of "echelon utilization" companies are. Due to the high cost and technical threshold, "small workshops" generally do not "echelon utilization" of recycled batteries.




The "regular army" has a lot of investment in technology and environmental protection, while the "small workshop" has almost zero investment in this regard, and can buy batteries at a higher price. The reality is that the "regular army" cannot compete with "small workshops" - a large number of retired power lithium-ion batteries flow into informal channels such as small workshops, bringing security and environmental risks.




Om een ​​degelijk recyclingkanaal tot stand te brengen, heeft het ministerie van Industrie en Informatietechnologie in 2018 ook de tussentijdse maatregelen voor het beheer van recycling en het gebruik van elektrische batterijen voor nieuwe energievoertuigen aangekondigd, waarin werd verduidelijkt dat autoproductiebedrijven kanalen voor het recyclen van stroombatterijen moeten opzetten verantwoordelijk zijn voor het recyclen van het gebruik van voertuigen met nieuwe energie en de energieverspilling die ontstaat nadat ze zijn gesloopt. Tegelijkertijd moeten lithium--ionbatterijbedrijven ondersteuning bieden bij het ontwerpen, produceren en recyclen van batterijen.




But for some car companies and battery manufacturers, recycling batteries is also a burden. Under the high labor cost and technical cost, some companies with a small recycling volume are "discounted" for recycling, and car companies rely more on "conscience" to recycle batteries.




In July 2021, the National Development and Reform Commission and other ministries and commissions jointly announced the "Notice on Printing and Distributing the "14th Five-Year" Circular Economy Development Plan", proposing to strengthen the construction of the new energy vehicle power lithium-ion battery traceability management platform and improve the new energy vehicle power lithium-ion battery recycling Use a traceability management system.




In August 2021, five departments including the Ministry of Industry and Information Technology jointly issued the "Administrative Measures for the Echelon Utilization of New Energy Vehicle Power Batteries", encouraging upstream and downstream companies in the industry to strengthen information sharing, and requiring companies to conduct power lithium-ion batteries according to given standards and actual data. Detect, evaluate residual value, and improve product performance, reliability and economy.




In any case, with the rapid development of new energy electric vehicles, the power lithium-ion battery recycling industry has become a "conspicuous science" at present, and a "blue ocean" is placed in front of the company.




The power lithium-ion battery recycling industry has a wide coverage and a long industrial chain, ranging from battery manufacturers to end-use companies, involving many. To effectively develop this "blue ocean", upstream and downstream companies need to work together. This should be led by automobile manufacturing companies, power lithium-ion battery manufacturers, recycling companies, industry associations, etc. to establish an industrial chain linkage mechanism for the new energy vehicle industry.v
