On the side of the lithium mine, it is not necessary, while the lithium-ion battery recovers unattended

Upstream lithium mine resources competition white heat, waste lithium ion batteries are left in garbage vendors. The latest data released by the International Energy Agency (IEA) shows that the metal lithium recovery rate is only less than 1% in 2021, and the two important battery metal recovery of cobalt and nickel can reach 35%, 60%, respectively. s level.

Many industry insiders tell reporters that there is an important reason for this phenomenon, or compared with cobalt, nickel, lithium recycling "low value". Can the global lithium city are hot and lithium resources can get rid of "waste" fate? The recycling market "no humanity" According to the reporter, in the current dynamic lithium-ion battery technology route, the lithium iron phosphate ion battery is absolutely dominated by the three-yuan battery, but the use of materials is different. Among them, the ternary battery is important for metal, cobalt, manganese, lithium, etc.

, due to its high energy density, good life, good low temperature performance, etc., occupying the core status in the 2nd year of the dynamic lithium-ion battery market, The lithium iron phosphate ion battery has important phosphorus, iron, lithium, etc., due to its high safety performance, low cost, is catching up this year.

". According to the data of the industry research institution, the data of illegitimate lithium-ion battery technology routes in 2020, the amount of lithium iron phosphate shipments accounted for 38%, and the ratio of the ternary batteries is about 62%, which in the first half of this year, iron phosphate Lithium-ion battery shipments are even more connected, and the monthly production of lithium iron phosphate ion battery this year even exceeds the ternary battery, and the rise is strong. Unlike the "hot" situation in the upstream manufacturing, lithium iron phosphate ion batteries are "cold" in the lithium-ion battery recovery market.

"Now the ternary battery recovery is much higher, the recovered lithium iron phosphate ion battery is not much. Lin Xiao, General Manager of Bo Culture, said in an interview with a reporter that "Due to the difference in the price of the price, from the current market market, the price of a ton of waste phosphate ion battery is about 3,000 yuan, but the waste three The price per ton of the yuan battery may reach more than 20,000 tons, and it is also to deal with a ton waste battery, and it is sure to find a big value. "Chen Yongyi, professor of the International Institute of Science, my country, told reporters:" From the market situation, lithium iron phosphate recyclable face.

For the company, iron and lithium value are relatively low. At the same time, the company also deals phosphorus may pollute the elements of the environment, and the recovery of lithium phosphate ion batteries can only be "no loss.".

"Due to the contradiction of lithium ore supply and demand" from the current phosphate technology route, in the recovery process, there is usually the soaking treatment of different solutions such as acid and alkali, and then refine the lithium, this process is high, and Waste water pollution may occur, in addition, many elements are difficult to mix together during the use of lithium-ion batteries for up to 10 years, and the complete separation cost is relatively high. "Chen Yongzhen told reporters. The reporter learned that the internal structure of the lithium-ion battery is more complicated, including steel shell or aluminum shell, positive material, negative electrode material, electrolyte, etc.

, usually classified as "harmful garbage". Many industry insiders told reporters that if a large number of retired lithium-ion batteries do not enter the compliance channel to achieve recycling or ladder use, it will not only have safety risks, but also cause environmental pollution. In fact, in the industry's view, "low value" waste lithium-ion batteries unattended this phenomenon, not only existing in the lithium phosphate ion battery market, there are similar to the lithium-ion battery used in large-scale question.

According to industry insiders, the value of lithium manganate-based ion battery used earlier, during the downtown period, even if there is still a situation in which people recover even if they are free. However, as of August 1, the price of the battery-level carbonate has risen by 91,000 yuan / ton, which is nearly 10% from the beginning of July this year, and it doubles over the same period last year. Behind the prices of lithium prices, but the global lithium resource development is in short supply.

According to IEA, by 2040, it is affected by metal consumption in the transformation of clean energy, and there will be surge in metal consumption in global lithium, cobalt, nickel, and copper. Among them, the demand for lithium will rise around 40 times, from the long-term, only Depending on the existing and lithium production projects, by 2030 will only meet the world 's approximately 50% of lithium demand, and from my country's situation, there are currently more than half of the lithium raw materials dependence. Policy escorts must be indispensable in the industry, and improve the lithium recovery efficiency in waste lithium ion batteries will alleviate tension in lithium mine production in a certain extent.

The data released by Everbright Securities is shown that in 2030, my country's scrapped phosphate ion battery will reach 313,300 tons, of which the iron-lithium-ion battery that can be used can reach 250,600 tons, and the total amount of battery to disassemble the recovery is about 6.27. 10,000 tons, which will be able to recover about 0.

28 million tons of lithium metal. Lin Xia said: "Now the lithium-ion battery is important or the market is driving, there is no forced to force lithium-ion battery recycling, if you can recycle low-value lithium-ion batteries in regular channels, compliance, can solve lithium resources The problem of 'return' is also expected to effectively prevent the safety hazards of the resilience of the lithium-ion battery. "IEA is also recommended in its latest report.

The total amount of abandoned lithium-ion battery in the future is expected to have a surge, which will bring huge battery recycling market space, and governments should introduce relevant policies as soon as possible to promote this field development. Among them, it will play a positive use of the raw battery to simplify the recycling process. In addition, in the industry's insiders, constantly improving lithium-ion battery technology, improving the battery structure will also be a major way to promote resource recovery.

Chen Yongzhen pointed out that the battery structure is now difficult, if the future new lithium-ion battery development can be contaminated by the full life cycle active material, not only convenient separation, which is conducive to reducing recovery costs, but also reduces treatment pollutants pressure. .
