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.

Based on forecasting, in 2020, the total sales volume of new energy vehicles in my country 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-ion battery. If it is used as a standard, the new energy vehicle power lithium-ion battery is recycled as a good business.

The opportunity has come, based on the use of the use of the power lithium-ion battery 5-8 years, from 2014 my country's new energy car enters the node of fast rise channels, the first batch of power lithium-ion batteries are close to the scrap The year, and this year is considered to be the first year of domestic power lithium-ion battery recovery. According to the prediction of my country's Automotive Technology Research Center, in 2020, my country's electric vehicle power lithium-ion battery accumulated waste will reach 120,000-17 million tons, and its market will exceed 30 billion yuan to 2022 yuan. A more embarrassing actual, facing the powerful power lithium-ion battery reported, 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 company is not completely thinking about how to dig this gold mine. Source: my country's automobile technology research center data resource center dynamic lithium-ion battery recycling "dead circulation" power lithium-ion battery is "dead circulation", in addition to new energy vehicles as new things, there have been no complete ecological closed loop, There are the following prices: 1. Technical threshold limited to anyone who wants to accept the recycling and utilization of the power lithium-ion battery, the current industry is recognized by two practices, one is the ladder utilization, one is a dismantling recycling.

Standing at the perspective of technology, these two practices have certain technical thresholds. First, the ladder utilization refers to the re-test screening of the recycled dynamic lithium ion battery. It is equipped with a packet for imaging, low-speed electric vehicles, etc.

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

Second, the power lithium-ion battery of less than 40% is to enter the dismantling recovery process. In theory, valuable metal elements such as nickel, cobalt, manganese and lithium salt can be dismantled from the retired power lithium ion battery, which can be recycled to the manufacture of new batteries. Similarly, the dismantling recovery is also facing the situation of different brands, different types of batteries, wherein the internal structure of the battery is designed, the series is parallel into group forms, the length of service and the use time, and the use of models and common conditions The dismantling method should also be divided into a separate class, and its difficulty is not a general small.

2. At the point where the high cost before the scale effect is stood in the market, if the profit of the dynamic lithium-ion battery recovery is high enough, then the so-called technical threshold will definitely be settled in capital, and it can be seen. Before the scale effect, the power lithium-ion battery recovery is actually a "lost money".

According to the relevant report, the most popular wet method recycles a ton of lithium iron phosphate ion battery is about 8,500 yuan, but the price of regenerated materials such as nickel, cobalt, manganese, and rare earth elements 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 is slightly better, but since the three-dimensional lithium-ion battery is the iterative product that is just completed, the large-scale bus is also in the past two years, this type There is still a period of time for the battery's scrap period.

The unprofitable dilemma corresponds to the actual situation of the power lithium-ion battery recovery market stagnation. 3. The residual value is too low, the owner "Sales" is inadequate, then the car owner drives the powerful lithium-ion battery to enter the willingness of the recycling channel? The actual situation is that the new energy vehicle is not high, only With a new car for 1 year, the price of the car will depreciate half.

Used cars do not sell prices, retiring batteries don't say it. Standing at the perspective of the owner, the power lithium-ion battery is the most expensive core component of a car, too disparity new and old difference, leading to the will of retiring the old battery. While you want to buy a low price, while you want to sell high prices, the power lithium-ion battery is recycled on the source.

In addition, a detail worth noting is, from time to time, this is true that the first batch of power lithium-ion batteries retired is true. 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 first batch of powerful lithium-ion batteries has limited total. The smart woman is difficult to be no rice, there is no sufficient recycling goal, the powerful lithium-ion battery recycling market is fully launched.

How to break? Dynamic lithium-ion battery recycling in the current time node is really facing many hindrances, but it is not avoided that these retired batteries are not entered into the recycling channel for environmental protection and energy saving. Lithium-ion battery recycling itself is also very economical in the future. The problem to deal with today is how to standardize the behavior of various 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. Tracking the source, ensuring that the battery flows to controllable due to the dynamic lithium-ion battery externally, it will be born to environmental pollution and certain safety hazards, and it is not necessary to take a mandatory means to enter the legal recycling channel.

If you want to "particle return", you can imitate the management mode of traditional fuel vehicles, bundle the battery, then bundle the VI code and recycle coding of the car, so that the battery will be scrapped, it flows to controllable. 2. 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 companies.

If the battery recovery cannot enter market-oriented operations in a short time, it is a "dirty living" "tired", then those who take subsidies or battery manufacturers should be responsible for the "good" of retired batteries? Stone can attack jade. Both Germany, the United States, Japan, etc. have established a very perfect "who processing, who is responsible", the power lithium-ion battery recycling system, and uses legal form to secure.

In this regard, if the information disclosed in the industry, all the information on the industry chain will be disclosed to the society, introduce the national supervision mechanism, the development of the industry or can get certain regulations. 3. The biggest difficulty in the recovery of the radiopulic lithium-ion battery is the traceability of the battery, and the "exchange" service of some car companies is currently separated, the ownership of the car is separated, the owner's way of paying the service fee To get a charging or power-exchange service, because the ownership of the battery is more controllable, so that the battery tracking and monitoring is more controllable.

Although the brand's gull gully, the power-saving station that establishes all the models can not be practical, but this business model is not a very good way of handling ideas.
