Recently, the National Standards Committee announced the notice of 312 national standards, including 3 national standards involving automotive dynamic lithium-ion batteries, GB / T34013-2017 "Electric vehicle power battery product specifications", GB / T34014- 2017 "Car Power Battery Code Rules", GB / T34015-2017 "Car Power Lithium Ion Battery Recycling Sub-energy Test". It is reported that these three national standards will begin to execute on February 1, 2018. In the industry, the introduction of 3 standards is significant for the recycling of the power lithium-ion battery.

Promote the construction of the recycling system in recent years, benefiting from policy, subsidies, my country's new energy vehicles have rapidly increased, currently my country's new energy vehicle insurance has broke through 1 million, and we will win the world, and 3-5 years will face severe practical - A large amount of power lithium-ion battery retirement. At present, many institutions and capital have predicted the amount of battery scrap in 2020, from 170,000 tons, 190,000 tons, 2.22 million tons, or even 500,000 tons, although the data is different, but all the power lithium-ion battery scrap volume will be described.

Rapid skyrocket. "At present, power lithium-ion battery recycling is accompanying new energy industry boom, which has become more hot, and a large number of capital and scale companies think this is an investment blue sea. "The general manager of the vice president of Bangu Group and the general manager of the Automobile Circular Division said in an interview with reporters.

"Dynamic Battery Product Specifications for Electric Vehicles" clearly specifies the monomers, modules and standard box size specifications of electric vehicle power storage batteries. This standard can effectively handle the pre-dynamic lithium-ion battery ladder, the power lithium ion battery also reduces the ladder recovery of the power lithium-ion battery due to the size of the size of the unshaldion of the energy storage device or household energy storage equipment. Threshold.

"Car Power Battery Code Rules" specifies the basic principles of power lithium ion battery, encoding object, code structure, and data carrier. This standard is announced, which can be controlled, maintained and traced back to the power lithium-ion battery, and the key parameters of electric vehicles, especially in the recycling link of the power lithium-ion battery, and more accurately determine the dynamic lithium-ion battery more accurately with traceability and uniqueness. Recycling responsibility subject.

"Car power lithium-ion battery recycling system residual test" standardizes the exterior inspection, polarity test, voltage discriminating, charge and discharge electrical current judgment, 余能, etc., for the vehicle power lithium-ion battery Holland test supply evaluation, help to improve the safety and scientificability of waste power storage battery. "These three standards take into account the full life cycle of the dynamic lithium-ion battery, through the development of the source system, open the entire chain, from the battery 'birth' to 'death' clearly visible, set a more complete foundation framework.

It can be said that it is built for the future of recycling the market in the future, in advance, lay the foundation. "The Secretary General of the Recycling Special Committee of Waste Battery, the general manager of Zhangzhou Haopeng Technology Co., Ltd.

said in an interview with reporters. Yu Haijun said that there are not many companies with powerful lithium-ion battery recycling and utilization in the market, and the above-mentioned standards have provided a reference to the industry, the battery factory, and government regulatory authorities, to a certain extent. The healthy development of the industry has positive significance.

Reduce the ladder using the threshold dynamic lithium ion battery after retiring from electric cars, if the pen is used for resource recovery, it will cause great waste, currently international, China has carried out related ladder utilization research and use. "The power lithium-ion battery will be retired from the electric car. It is probably used by 1/3-1 / 4 energy, life, and the residual energy is still very large.

Exploring the tradder is feasible from value perspective. "Shen Wanhongyuan Securities a Decomposition Tellors. It should be said that the introduction of the above three standards reduces the ladder of the dynamic lithium-ion battery, but a problem that is unavoidable is that the ladder is still facing the bottleneck in the actual situation.

"There is a difference between the retired battery cells, especially the average, and sometimes the decay of energy is non-linear, and the cliff type is as determined by the use of wooden bucket theory - the shortest wooden board. The worst battery determines the entire Performance of the energy storage system. "In the interview, many experts told reporters.

In the district Hancheng, the current domestic ladder is still a new thing, the market acceptance is low, because the current amount of scrapped battery currently has no more economic benefits, and several years later, such as a single model of 2020 When the scrap cell reaches thousands of sets, the tradder is also economic value. This is a process of market cultivation. "In the second half of this year, we will have two ladder utilization of the distributed project.

The current technical exploration has been completed. "District Hancheng revealed. The recycling is difficult, and the national subsidies have not yet, although the above three standards will promote the recycling of power lithium-ion batteries in large development, but from the technical, the power lithium ion battery, especially the recovery of the power lithium-ion battery.

Certain difficulty. "The core of the problem is that the existing structure of lithium battery is not suitable for recycling, too high cost, and truly dealing with these difficulties, it is necessary to break through the technical direction. If it is easy to recover at the end, it is necessary to redesign on the material structure.

"Chen Yongzhen, the head of the China Academy of Electrotechnics, China Institute of Electrical Engineering, to the reporter. According to Chen Yongzhen, the internal structure of the current dynamic lithium-ion battery continues the bond electrode of the mobile phone lithium-ion battery. After crushing, then the wet process, recover the purification cobalt, nickel, lithium, etc.

, and also brings waste in the recovery process. Solve environmental expenditures, high recovery costs. Chen Yongzhen also proposed, "With the continuous break of dynamic lithium-ion battery technology in the future, there will be many technical forms in a few years, and it will constrain the existing technical standards, or insufficient.

Standard is a process of gradually establishing and continuously improved. "According to reporters, my country is abandoned electronics, such as" four-machine and one brain "(TV, refrigerator, air conditioner, washing machine, computer), and lead-acid battery recovery have corresponding financial subsidies, but The recovery of the power lithium-ion battery has not yet any financial subsidies, although Shanghai and Shenzhen have introduced corresponding policies, but the operational rules that have not yet been introduced. In the above-mentioned decomposition, "recycling subsidies will not be introduced, because lead and lithium are different, the residual value of lead is large, and the residual value of lithium is very small.

"The recycling is difficult, there is no state of the subsidy, how do the economic account of the power lithium-ion battery recycling company? Yu Navy believes that" as we look at it, there is no big problem with the technical route, achieving profitable The only obstacle is a scale problem. In the long run, no matter which power lithium-ion battery, as long as you have leading technology, it has a large-scale condition, and it can be profitable without subsidies. ".
