Technical threshold is limited to what is the power lithium battery recovery gold mite unmanned?

The new energy car is the current windy air, in the downstream car market, last year's sales reached 12.56 million, up 61.7% year-on-year, and the front is nothing right.

According to the forecast, in 2020, the total sales volume of my country's new energy vehicle will reach 5 million, of which 2020 will reach 2 million units. A very simple calculation question, how many new energy cars, how much driven the power lithium battery. If this is used as a standard, the new energy vehicle power lithium battery recovery seems to be a good business.

The opportunity has been here, according to the use of the power lithium battery 5-8 years, from 2014 my country's new energy car enters the node of the fast rise channel to calculate, the first batch of power battery is close to the annual limit of the scrap, This year is considered to be a domestic power lithium battery recovery in China. According to the forecast of my country's Automotive Technology Research Center, by 2020, my country's electric vehicle power lithium battery accumulated drain will reach 120,000-17 million tons, and its market will exceed 30 billion yuan to 2022 yuan. A more embarrassing reality is that in the face of the raging power lithium battery, the market has not established a sound recycling network to supplement this ecological short board, and the battery manufacturers, car companies and even professional in the industrial chain.

Battery recycling companies have not completely thought of how to dig this gold mine. Source: my country's automobile technology research center data resource center dynamic lithium battery recycled "dead circulation" power lithium battery is "dead circulation", in addition to new energy vehicles as new things, there is no complete ecological closed loop, there is still the following Several reasons: 1. Technical threshold is not to accept the recycling and utilization of the dynamic lithium battery.

At present, there are two practices, one is the ladder, one is the dismantling recycling. Standing at the perspective of technology, these two practices have certain technical thresholds. First, the ladder use refers to the recovery of the power lithium battery recovered, and is equipped with a sequential area of ​​material storage, low-speed electric vehicles, etc.

, according to industry standards, power lithium battery capacity attenuation to 80% to the retired time limit, although no longer apply to the car, but in other respects, "waste heat" can be used, there is a large use of space. However, when these batteries are reused, the electrochemical performance, life attenuation of the battery is detected, and the battery is selected, so that the battery can be guaranteed to ensure the consistency of the battery and the safety of the entire battery system. However, for a long time, the new energy vehicle power lithium battery has not formed a unified standard, which also causes the power lithium battery from the first lead-acid battery, to the subsequent nickel-cadmium battery, nickel-hydrogen battery, and then go to the current ternary lithium ion There are a wide variety of batteries, how to make these standards, different batteries of different technical structures, are not a simple matter.

Second, the power lithium battery having a capacity of less than 40% is to enter the dismantling recovery link. In theory, valuable metal elements such as nickel, cobalt, manganese and lithium salt can be dismantled from the retired power lithium battery, which can be recycled to the manufacture of new batteries. Similar to the ladder, disassembly recycling should also face the situation of different brands, different types of batteries, in which the internal structure of the battery is designed, the series is parallel into group, the length of service and the use time, the application model and common conditions The dismantling method should also be divided into a separate class, and its difficulty is not a general small.

2. On the high cost standing in the market, it is high enough to say that the profit of the power lithium battery recovery is high enough. Before forming a scale effect, the power lithium battery recovery is actually a "lost money".

According to the relevant report, the wet method of the current penetration rate is 10500 yuan, but the price of nickel, cobalt, manganese, rare earth element extracted from the battery is only 8100. Yuan, this also means that the recycling company wants to "fall" 400 yuan. In contrast, the dismantling of the three-yuan lithium-ion battery should be slightly better, but since the three-dimensional lithium battery is the iterative product that has just been completed, the large-scale bus is also in the past two years, this type of battery There is still a period of time for the scrap period.

The unprofitable dilemma corresponds to the reality of the power lithium battery recovery market stagnation. 3. The residual value is too low, the owner "unsupported" is inadequate in the dynamic power of a deadlock, then the power of the car owner drives the powerful lithium battery to enter the recycling channel.

The real situation is that the new energy vehicle is not high, only a new car for 1 year, the price of the price is half. Used cars do not sell prices, retiring batteries don't say it. Standing at the owner's perspective, the power lithium battery is the most expensive core component of a car.

It is too disgusting new and old difference to lead the wishes of the owner's retired old battery. While you want to buy a low price, while you want to sell high prices, the power lithium battery is recycled on the source. In addition, a payable detail is, from time to time, this is true for the first batch of powerful lithium battery retirement.

However, according to sales statistics, the total sales of new energy vehicles in 2010 to 2013 will not be 50,000, which means that the total amount of powerful lithium battery scrap has limited. The smart woman is difficult for the rice, there is no sufficient recycling target, the power lithium battery recycling market is fully launched. How to break? Dynamic lithium battery recovery is indeed a lot of hindrance in the current time node, but it is not avoided that these retired batteries must enter the recycling channel for environmental protection and energy saving, standing in the market, power lithium battery recycling itself in the future Also very economical, the problem now to solve is how to standardize the behavior of all parties in the industrial chain, establish a set of responsibility, rights, proficiency ecosystem or business model.

Intelligent relativity is considered to be considered from the following aspects. 1. Trace the source to ensure that the battery flows to controllable due to the dynamic lithium battery externation does have environmental pollution and certain safety hazards, and thus the mandatory means will be taken to enter the legal recycling channel.

If you want to "particle return", you can simulate the management mode of traditional fuel vehicles, bundle the battery, and then bundle the VI code of the car and the recycled encoding, so that the battery will be scrapped, it flows to controllable. 2. Whoever produces who is responsible, can not only know how to make a subsidy is not good, my country's new energy car market is ripening by policy, the huge subsidies of the country have become a lot of car enterprises.

If the battery recovery cannot enter the market-oriented operation, it is a "dirty" "tired", then do you take a subsidized car enterprise or battery manufacturer should be responsible for the "good" of the retired battery? Stones from other hills, can learn. Germany, the United States, Japan and other countries have established a very perfect "who produces, who is responsible", the power lithium battery recycling system, and uses legal form to secure. In this regard, if the information disclosed in the information is public, the information on all the links on the industrial chain is disclosed, introduced into the national supervision mechanism, the development of the industry or can get certain specifications.

3. The biggest difficulty in the recovery of the radio power lithium battery is the traceability of the battery. At present, some "power-exchange" services launched by car companies, separating the ownership of the battery and the owner of the service fee.

Get charging or power-on service, because the ownership of the battery is more controllable. Although the gully between the brands is in front of the game, the power-saving station to establish a service all models may not be practical, but this business model is not a very good solution.
