How many of us have passed the panic of "battery pollution". There is such a research data, saying that a general battery is discarded into nature, there is a possibility of pollution of 600,000 water, equivalent to a person's life. Detact, it is difficult to take it.
However, the waste battery will not be properly resolved, will pollute the environment, which is almost consensus. Electric cars should be "true environmental protection", from battery processing, service, retire to rebirth closed-loop to open. Whether it is a policy, or profit-driven.
my country's new energy vehicle's starting phase can be traced back to 2009, and now, there have been more than 10 years of development. In the early stage, public transport or rental industry as a pilot, from 2015, new energy vehicles gradually be accepted by household users, stepped into size production. Under normal circumstances, the life of the power lithium battery is 5-8 years.
Therefore, the size of the first wavelength lithium battery will appear in 2020. Industry Forecast 2020 battery retirement is 25GWH, according to weight, Johimo is 200,000 tons. Retired batteries are not equal to thorough scrap, scientific recycling is still considerable market value.
According to industry decomposition, 2019-2025, the market value may exceed 60 billion yuan. How to recycle the power lithium battery? The time node of scale retirement is basically clear, and the power lithium battery recovery has arrived at the time of acceleration. Simply discussed the recycling technology, after entering the recycling factory, a piece of power lithium battery will generally carry out a tradder utilization and regeneration utilization.
The first step in recycling, the factory must first test, classify, repair, or reorganize the retired battery. If the battery itself is relatively good, then the "ladder utilization" principle can be followed, or then repair the factory, or "downgrade" to the communication base station, the energy storage base and other places continue to service, or return to the low-speed electric vehicle market until the performance is not Requirers. Electricity system energy storage demand is a critical market for battery ladder.
Some foreign car companies regarding battery traders are exploiting some applicable patterns. For example, Japan Mitsubishi will use the retired battery to power the building, Audi, Renault and other European car companies are also trying to retire the combination of battery and building power. Insert a question: Although the Nanfu gathering is finally proved to be just a marketing set, but it is used in the "toy car" in its advertisement, it can be used in the remote control.
"This is the basics. Ladder utilization case. However, if there is no trading value, all the batteries will eventually come to the link of "regeneration use".
After that, the retired battery will be dismantled, broken, smelted, thus extracting key materials such as cobalt, manganese, nickel, and then returning to battery processing, re-use, and the entire closed loop is turned on. The technical approach to renewable use is important, there are three types: dry method, chemical method, biological law 1, dry method, simple understanding, is physically dismantling, resource classification. The positive and negative material is separated in the room, which will be handed over to the smelting company, copper aluminum material to give metal recycling company, mixing the electrolyte of various chemical and heavy metal materials, isolated on the outdoor, and is further further use.
These price materials are ultimately possible to return to the battery and process, or reuse in other industries, which is the potential value of battery recovery. 2, the chemical method, that is, the metal ion is transferred from the electrode material to the leaching medium, and the metal ions are produced in the form of salts, oxides by ion exchange, precipitation, adsorption, etc. Extract from the solution, important include wet metallurgy, chemical extraction, ion exchange, etc.
3, biological method, important use of microbial leaching, convert the useful components in the system into soluble compounds and selectively dissolve, realize the separation of the target component and the impurity component, and finally recover lithium, cobalt, nickel, etc. At present, the key issues of biometric recovery technologies are not yet mature, and the key issues such as transaching and leaching conditions are still to be treated. What is the pain point of the power lithium battery recovery? In the "Pipeline Road" documentary in the car, it is mentioned that the difficulty of recycling of dynamic lithium battery is not technical, more in the industry standard.
In fact, in 2012, my country announced the "Energy Saving and New Energy Automobile Industry Development Plan", and has been deployed for the recycling of dynamic lithium battery. In recent years, it has also been intended to introduce a number of policies that have been detailed from the command. For example, in 2018, the seven ministries jointly issued the "Interim Method for the Management of New Energy Automobile Power Battery Recycling", which started to implement, emphasizing the "power lithium battery recycling and implementation processing workers' responsibility extension", requiring car companies to bear The main responsibility of the battery recovery, and refers to the first tradder utilization of the retired dynamic lithium battery, and resource recovery is carried out.
On March 27, 2020, the Ministry of Industry and Information Technology announced "2020 Industrial Energy Saving and Comprehensive Utilization Work". In 20 big items, there are 4 auto classes, including promoting new energy vehicle power storage battery recycling system construction. Who is the responsibility of the battery recovery? Who stood out to take the initiative to drink, this is a problem that is not dealt.
Car companies undertake the main responsibility of battery recovery, taking into account the processors as electric vehicles, can master more data on battery traceability, more advantages in achieving. The incentive policy is a big push, but at the same time, the economic account of the car company is also clear. Consumers' concerns about electric vehicles are low in the value, and the importance is the decline of the battery, and the cost of replacing the new battery is very high.
If the battery is "favorable map", whether it is also expected to reduce the cost of the electric vehicle to replace the new battery, and improve the value of electric vehicles? In recent years, in the electric motor industry, it began to popularize a "protection promotion" policy. Under the brief description, that is, the manufacturer is promised, when the new car uses a certain period of time, you can repurchase the old car according to a certain discount (more than two years, generally six% discount). The meaning of repurchase policy is to cancel the user's concerns about electric vehicles, and there are manufacturers' credits to make back books, pay more assured.
Due to fewer sales, manufacturers have a certain budget, you can overlook this "repurchase expenditure". But if you want to continue, it is still subject to the cost problem of the battery, and whether you can dig higher value on the retired battery. In this way, "Recycling Relay Rod" is still returned to the battery recycling factory.
If the recycling factory can continue to reduce the technical cost, Zhang Da reclaim the market value of the income, then it is possible to recover the retired battery with a higher price, and the value of electric vehicles will not be so low. However, the contradiction is just here, selling raw materials, and it is necessary to hope that the price is, the better, and the price is lower. At present, there is no scientific pricing model between the car enterprise, the battery recovery plant and the battery manufacturer.
Any party discovering that the sale does not make money, the formation of the closed loop in the industry will affect. Therefore, the cooperation mechanism must also grind, the relevant standards must also fill the blank. But as long as the technology continues to advance, cooperation continues to advance, will be better tomorrow.
▎ Battery recycling is an underestimated blue sea market? Recycling for retired batteries, natural with a certain public welfare. After all, the starting point is still to protect the environment. The three-dimensional lithium-ion battery contains nickel, cobalt and other scarce metals, and the regeneration is high, so the market value is also very large.
When the scarce metal is increasingly "scarce", the cost of straight procurement will also be more and more high, and the metal resources that are regenerated may be more competitive. So, the potential of Blue Sea is still foreseen. However, the current market is more than the medium and small company, it is difficult to form a scale effect, and the profitability is difficult.
This market should be "big company" layout, to integrate scale, but because of a certain public welfare nature, it is required to move purely, you can't always think about "earning a vote", heavy asset investment, and long wait, Be a test. In April this year, the Wu Mine Group Changsha Mining and Metallurmur Institute of Changsha has established a domestic third-party power lithium battery recovery service platform, driving the industry's power lithium battery recovery. In June this year, the BYD trail recycling center landed in Shandong.
The main cart electrical separation mode of the car is also the top priority. Weima car has a layout for battery recycling business. Blue sea is still in, difficulty is not small.
I hope that one day, the wind blows up, the appearance of "unicorn" is not unexpected.
