It is not necessarily baby, but sometimes, baby often will be abandoned. On the occasion of endurance, the domestic dynamic lithium-ion battery research and development level is continuously improved, and the electric vehicle for battery life has become an optional car product. However, the capacity of the power lithium-ion battery gradually decreases, and the electric car life is reduced, which means that the vehicle life of the power lithium-ion battery will eventually sleep.

In the next few years, the recycling of a large-scale retired dynamic lithium-ion battery will become a hundred billion large cake. Industrial practitioners are involved, to force, opening up a new conquest battlefield. However, the difficulty of the dynamic lithium-ion battery recovery process is less than its manufacturing production process, there is still a difficult point to overcome, and the standardized recycling process is the first problem that needs to be solved.

The national standard is still demolished. "This is the earliest policy of my country's earliest car recycling. From the global perspective, there is no country specializes in the establishment of corresponding regulations for power lithium-ion battery recycling.

"my country's Automotive Technology Research Center Automotive Standardization Research Institute. Zhang Pillar said that "Electric Vehicle Power Battery Recycling Technology Policy (2015)" (referred to as "Technical Policy") The minister was jointly formulated and announced in January this year, aims to guide the company to reasonably carry out the design, production and recycling of electric vehicle power storage batteries, establish the power battery recycling system of upstream companies, and point out that the technical policy is suitable for China Dynamic battery design, production and final disposal of the production and waste power storage battery in the people's Republic of China. From the technical policy, at present, my country has built a set of standard systems around the power lithium-ion battery, packaging, storage, dismantling, residual detection, ladder utilization, material recovery, etc.

In terms of, every link is crucial. For example, packaging is transported, because the state of waste battery is unstable, there may be damaged, leakage, if it does not carry out reasonable package and safety treatment, it is likely to cause short circuit, fire, and even explosion during transportation. As the last link of the entire process, the material recovery process can be extracted in which the material is still valuable, and the manufacturing process of the new battery is used to turn waste into treasure, reduce environmental pollution.

Zhang Pusher also said: "At present, the standard of recycling," the use of disassembly and use of vehicle power lithium-ion battery recycling "," The use of the vehicle power lithium-ion battery recovery "has passed the national admission It is expected that the implementation can be announced in 2017. In addition, related criteria for disassembly, packaging transportation, ladder utilization, material recovery are also being developed. "He also mentioned the future standard work plan: disassembly, packaging and transportation, ladder utilization, material recycling, these four standards officially issued in August 2015, the end of 2016 to early 2017, expectation to announce the implementation of the 2018.

The reporter learned from Zhang Capping, the electric vehicle unit (referred to as "Working Group"), which is responsible for battery new products, including battery cells, modules, battery packs, charging related facilities, etc. Work. In addition, the autoMarrator Commission has also established a direct road vehicle recycling marking committee, which should consider the recyclable utilization, including harmful substances, reduction in heavy metals, how to be more safe and effective, and how to be more safe and effective.

At present, the Working Group is composed of battery production company (CTL, Chaowei, Lishen, Hefei, etc.), recycling company (Bangu, Greenmei, Bartrei, etc.), industry associations, testing institutions, foreign companies in China The scale is huge, which reflects the attention of the country's recycling of dynamic lithium-ion batteries.

According to the public data of the batch recycling, my country's powered lithium-ion battery loading is about 15.7GWH; predicting that the demand for power lithium-ion batteries in 2020 is about 71.7GWH.

However, the dynamic lithium-ion battery recycling is still facing difficult to have a large-scale dilemma. It is important because the battery received by the recycling company includes various forms, sizes, specifications, package forms, making the dismantling involve a variety of package clamps, companies It is difficult to achieve large-scale batch dismantling. In this regard, Zhang copper column should be given to how to carry out post-recycled use, such as standardized size, module, and the product should be uniformly identified and standard, which is easy to identify what battery can be used.

Increased recycling, Hunan Bangpu Waste Automobile Circuit Co., Ltd. (referred to as Bangu) General Manager Yu Navy recommends that the government has developed companies with recycling professional levels, such as investment construction plants, production, environmental factor Wait.

You can also explore funds, deposits, or mandatory management methods to promote dynamic lithium-ion battery recovery. For example, in Europe, each kilogram of power lithium ion battery gives 3 euros to recycle treatment fees; US will give $ 4.2 / kg of treatment fees, etc.

In 2005, Bond Group was founded, and it was a minimum of national-level torch plan, which had a small number of automobiles and battery recovery, and high-tech companies. The three major industries of the battery cycle, the automotive cycle, and the new materials constitute its special industrial system, of which the automotive circular base is important for vehicle and power lithium-ion battery recycling, and has a global advanced waste battery orientation cycle recycling technology. Ten of waste battery recycling standards.

It is reported that many members of the workgroup, the specific written core team is taken by Bangpu as a lead unit, and as a leader of the core preparation group, it has played a very important use in the pre-standard system pre-planning. "Ten years, we have been doing the recycling of lithium-ion batteries, we specialize in battery recovery, more good at being a recovery process of lithium-ion batteries. "Yu Navy said that there are some companies that do batteries, but the entry threshold set by the country is relatively high, so there is not much company in the company's list of powertranium-based batteries identified by the country.

Hunan Province has only Bangpu, a company is recommended to the Ministry of Industry and Information Technology. "From this year, after the technical policy and management method of battery recycling, the entire industry, including battery production company, vehicle company, recycling company, the standard of recycling of battery recycling is very concerned, and it has also joined in. "Zhang copper column said.

It should be pointed out that the waste power battery includes the remaining capacity and charge and discharge performance after use, or the power battery that is no longer used after other reasons is removed; the power storage battery on the electric vehicle; Dynamic battery; production process, company scrapped power storage; other power storage batteries that need to be recycled; also include waste battery packs, battery modules and monomer batteries. Yu Haijun said: "my country's current battery recovery is very low, the real recovery rate is less than 3%, and the power lithium-ion battery of new energy vehicles is relatively large, the energy density is high, and it also involves heavy metals, electrolyte. And environmental issues.

For our company, the professional is to do this. At present, we have two national standards (dismantling norms, and residual testing specifications) have been approved. "Compared with the development of international power lithium-ion battery recovery, Yu Navy is also analyzed:" my country is the first country that is the first power lithium-ion battery recovery standard, and the system constructs a relatively forever, the development of new energy vehicles has become Part of the national development strategy, foreign new energy vehicle development, the government's driving force is far from we so big.
