Power lithium battery will welcome large-scale 'reported scriptures' three bottlenecks need to be broken

my country’s powered lithium battery will usher in the “reporting of the tide”, by 2020, the credit will exceed 248,000 tons, approximately 20 times the 2016 annual report. Such a large-scale “reportable tide”, the face is a serious recycling situation. How to safely recycle, environmentally friendly, strengthen the standardized circular utilization of waste dynamic lithium batteries to prevent such new solid waste from causing “catastrophic” environmental consequences, and become the “expert-level problem” in the industry’s universal attention.

According to industry research institutions, my country’s powered lithium batteries will usher in the “reporting waste”, and the report will be more than 248,000 tons to the 2020 year, about 20 times the 2016 report.. Such a large-scale “reportable tide”, the face is a serious recycling situation.

How to safely recycle, environmentally friendly, strengthen the standardized circular utilization of waste dynamic lithium batteries to prevent such new solid waste from causing “catastrophic” environmental consequences, and become the “expert-level problem” in the industry’s universal attention. Experts suggest that the recycling system of waste dynamic lithium battery will be established as soon as possible, relying on the industry’s backbone company, forming a national-level engineering research center to crack the technical bottleneck, establish a technical support system, and promote new energy automotive industry chain green sustainable development. In the past 3 to 4 years, we have ushered in the “Retirement” in recent years.

In the context of environmental problems, the energy diversification strategy has gradually developed consensus, multinational governments have increased the support of new energy automotive industry, the new energy automotive industry enters Rapid development phase. Industry insiders said that domestic new energy vehicles currently focus on the area of ​​government procurement decisions, such as logistics cars, sanitation vehicles, business cars and other public domains, but private consumers have gradually improved new energy vehicles..

Tang Hongwei, General Manager of Changsha Team Technology Co., Ltd. engaged in new energy sharing car operation, believes that with the advancement of national subsidy policies and gradual improvement of charging facilities, the rise in China’s new energy automotive market will gradually drive steering from the public domain.

Driven by private sector, home new energy passenger car market will enter high-speed rising period. According to industry research institutes, the production and sales volume of domestic new energy vehicles in China will remain rapidly, and the annual complex increase is expected to exceed 30%..

The new energy vehicle market presents an explosive rising, directly driving the scale of the power lithium battery rises.. In 2015, my country’s powered lithium battery output value was 38 billion yuan, up 262% year-on-year, and the output value approached digital lithium ion battery.

. In 2016, my country’s powered lithium battery output value was 64.5 billion yuan.

The first time exceeded the scale of traditional digital lithium ion batteries, and became the largest field of lithium-ion battery consumption structure.. With the introduction of a new round of promotion policies, and the future of lithium-ion battery production technology, cost decline, etc.

In the next five, the dynamic lithium battery demand for new energy vehicles will rise at high speed, 2016 my country’s automobile power lithium battery production For 30.8GWH, it is expected that my country’s automobile power lithium-ion battery production will reach 141GWH in 2020..

Li Changdong, chairman of Hunan Bangpu Circular Technology Co., Ltd., told the “Economic Report” reporter, currently 3,000 lithium iron-free battery life of 3,000 cycle life can reach 8 years, but the battery life will be short under practical conditions, and it can be used.

5 years. Since the three-dimensional dynamic lithium battery technology is relatively late, maturity is not as good as a lithium phosphate ion battery, the service life is relatively short, and the average life is 4 years under conditions of condition..

“The first batch of power lithium batteries in 2012-2014 will have a large-scale retirement before and after 2018.. Dynamic lithium-ion batteries will appear in the next 3 to 4 years.

. Li Changdong said. It is predicted that as the size of the electric vehicle market continues to rise, it is expected that the drainage volume of the power lithium battery will also rise rapidly.

. In 2016, the drainage volume of lithium battery is about 12,000 tons. By 2020, my country’s powered lithium battery scrap will reach 248,000 tons.

. Recycling and recycling part of the difficulty part of the experts believe that from environmental governance and resource utilization perspective, waste dynamic lithium battery recovery and circular utilization will become an important part of the new energy automobile industry. According to industry insiders, existing powered lithium battery production, lithium iron ion batteries dominate.

It is worth noting that it is driven by the TSLA boom. Some companies in China explore the three-membered materials such as NCM (nickel-cobalt manganese) and NCA (nickel-cobalt aluminum) for power lithium batteries..

Since 2014, there is a three-way power lithium battery production line for passenger cars in China.. Cao Hongbin, a researcher of the Institute of Process Engineering, my country, told the “Economic Report” reporter.

Before 2013, there was a serious problem in the domestic lead-acid battery recovery industry, and the lack of qualified individuals and small workshops illegally recycled lead-acid batteries, directly discharged waste pickup, The environment has serious pollution, and the lessons are very heavy.. The industry is generally believed that although the new energy vehicle power lithium battery is important to use a relatively environmentally friendly lithium-ion battery, it is more polluted by lead-acid battery, but if the recycling is improper, it is also very likely to repeat the contrast of lead-acid batteries.

Causes serious pollution to the environment. In view of the upcoming powerful lithium battery “Return” is coming, it can’t fall to the possible environmental pollution..

“Waste dynamic lithium battery containing heavy metals, electrolytes, fluoride containing fluorine-containing organics, also pollution; Improper operation during processing, it may bring a number of problems such as fire explosion, heavy metal pollution, organic waste emissions.. Cao Hongbin said.

“Li hexafluorophosphate in the electrolytic solution in the electrolyte of the power lithium battery is used as an example. This solute is easily hydrolyzed in the air environment, and there is a harmful substance such as pentafluoride, hydrogen fluoride. It is strongly corroded to the human body, so it is necessary to pay special attention to the solvent and hexafluorophosphate.

Process. Wonderful, very likely to bring ‘secondary pollution’, or even catastrophic consequences. Li Changdong said.

Although pollution is like “Dhakelis’s Sword” high hanging, on the other hand, the use of used vehicles is a very value “urban mineral”, if used, not only reduces environmental pollution, but also Can “turn waste into treasure” to prevent waste of resources. Xu Shengming, a researcher at Tsinghua University Nuclear Energy and New Energy Technology Research Institute, said that raw materials such as cobalt, nickel, lithium, such as power lithium batteries are very important strategic resources. At present, my country’s 80% cobalt and 70% lithium, nickel resources depend on import.

“my country’s cobalt resources are relatively poor, cobalt is less than a few thousand tons, but the amount of use reaches tens of thousand tons, so it is basically imported from countries such as democratic Congo, Africa, but these national political situation is not very good.. New energy automotive industry has developed very fast, cobalt has been supplying.

Xu Shengming said. In the industry believes that although there is no cobalt resources, my country has imported a large amount of cobalt mines every year, and there is a large number of domestic storage, and 70% of domestic cobalt’s overall protection is concentrated in battery production..

If you can use these cobalt resources to recycle, you can greatly reduce the dependence on foreign imports, which is conducive to the healthy development of new energy auto industry.. “Lithium, nickel, cobalt in the ore is very low, only 0.

5% of nickel in nickel nickel; cobalt oxide ore is only 0.2%; the lithium in the brine is only 0.02%.

And the total amount of nickel + cobalt + manganese in the waste ternary dynamic lithium battery is 20%, and the waste lithium ion battery contains 3% lithium, and the total amount of nickel cobalt in the waste nickel hydrodynamine is 40%, and the rare earth 6 % Or so, the price of metal tastes in the waste battery are 40-100 times the original mine.. “Professor of the Metallurgy and Environmental College of Central South University.

“The general service life of the power lithium-ion battery is about 8 years, but the capacity of the vehicle power lithium-ion battery will be discarded when the capacity of the lithium-ion battery is below 80%, and the actual use time is about 3-6 years.. Before the material or energy of these discarded vehicles, they can be used for power grid energy storage or as a low grade power source, establish a secondary utilization system of the battery step, and give full play to lithium ions.

Battery’s social and economic benefits. Xu Shengming said. Three major bottlenecks need to be broken, although the importance of waste dynamic lithium battery recycling is consensus in the industry, its circular utilization market is still in the germination stage, whether it is policy regulations, process technology or recycling systems, and needs further strengthen research and regulation.

. First, the policy and regulatory support and binding are not enough..

According to industry, my country has developed “Dangerous Waste Polishing Prevention and Treatment Technology Policy”, “Waste Battery Pollution Prevention and Treatment Technology Policy”, 2016 National Development and Reform Commission led the “New Energy Automobile Power Battery Recycling Technology Policy”, 2017 State Staff Committee announced National Standard “Specialist Specification for Recycling Demolition and Utilization of Velive Lithium Battery”. All of these policies and technical standards are guided or recommended guidance documents, and the backbone companies on business regulations have reference guidance purposes, but there is no constraint for criminals..

Second, the recycling treatment technology lags. The entire process of recovery treatment of waste dynamic lithium ion battery includes dozens of complex steps such as discharge, dismantling, crushing, sorting, intrinsic, elemental synthesis, involving multiple cross-disciplines such as physics, chemistry, materials, engineering, technical complex lengthy. At present, there are many developed countries such as Germany, the United States, and Japan, including Germany, the United States, and Japan are actively supporting and promoting national key technological engineering research and development in the field.

. my country has a little lag in a relatively international peer in terms of power lithium battery recovery technology technology..

Third, the recycling network system is not perfect. According to my country’s car power lithium battery recycling, the recycling network of the power lithium battery should be responsible by the automobile production company, but my country’s automobile production companies often move to battery suppliers, and battery production companies have no national recycling. Network, plus the cost of construction of outlets, the current national recycling market is extremely irregular, the whole is in a “no business, no card, no brand,”.

In response to the above questions, experts suggest that the establishment of transparent and smooth waste lithium battery recycling networks, changing existing “paying” business recycling models, adopting Japanese countries such as “charge-based” processing method, thus Conacular to long-term development. At the same time, we should also make full use of research and development forces such as colleges, companies, and increase research in recycling technology, and internationally. First, promote the establishment of a benign recycling system that can be monitored.

Start design from the power manufacturing stage, by means of the Internet, the Internet, the manufacturing, circulation, and recycling of power lithium batteries, prevent local dismantling of small traders, and achieve full recycling of each set of power lithium batteries, and establish a benchmark Promotion to parallel recycling field. Second, explore the ladder utilization technology of the power lithium battery. Considering that the power lithium battery contains a higher amount of ingress, it should be further explored how to safely and efficiently realize the ladder utilization of the power lithium battery.

. Third, explore more efficient cleaning production technology. Explore how to efficient and short-range implementation classification in dismantling technology; explore metallurgical technology-oriented metallurgical technology in metallurgical technology; in-depth development of more cleaned metallurgical technology, prevent “secondary pollution”.

To this end, the relevant state departments may wish to support the backbone companies in the field of powerful lithium batteries from funding, policies, intellectual resources, and research institutes should jointly establish a national-level engineering research and development center for powerful lithium batteries as soon as possible.
