In recent years, in the context of environmental problems, the energy diversification strategy has gradually developed consensus, multinational governments have increased support for new energy automotive industry, and the global new energy automotive industry entered the rapid development stage. 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 the research institute of Lithium Events in the Industry Zhicu High Workers, the production and sales volume of domestic new energy vehicles in China will rise rapidly in the next five years, 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.

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 within 3 to 4 years‘Newspaper’. Li Changdong said.

According to the research institute of high-run research, the scale of the electric vehicle market is constantly rising, and the amount of scrapped volume of the power lithium battery will also increase 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 the Temla boom drives, some companies have some companies to explore the three-membered materials such as NCM (nickel-cobalt) 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 research firm of the Institute of Process Engineering, my country, told reporters that before in 2013, the domestic lead-acid battery recovery industry has serious problems, lack of qualified individuals and small workshops illegally recycled lead-acid batteries, directly discharged waste acid, and cause serious pollution to the environment. Teaching is very heavy.

The lithium hexafluorophosphate in the electrolytic solution of the power lithium battery is used as an example. This solute is easy to hydrolyzate in the air environment, and there is a harmful substance such as pentafluoride and hydrogen fluoride. It is strongly corroded to the human body.

Therefore, pay special attention to the solvent and hexafluorophosphate. deal with. It is very inadvertent, it is very likely to bring‘Secondary pollution’, Or even catastrophic consequences.

Li Changdong said. Although pollution is like the Sword of Damoclis, on the other hand, the use of the useful vehicle power lithium battery is a very value of urban minerals. If used, it can not only reduce environmental pollution, but also be turned waste Bao, prevent waste of resources.

Xu Shengming, researcher, Nuclear Energy and New Energy Technology Research Institute, Tsinghua University, said that raw materials such as cobalt, nickel, lithium, and lithium batteries such as dynamic lithium batteries are very important strategic resources. At present, my country's 80% cobalt and 70% lithium, nickel resources are dependent. import.

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. Establishing a transparent and smooth waste battery recycling network Although the importance of waste dynamic lithium battery recycling utilization has reached a consensus, its circular utilization market is still in the germination stage, whether policies and regulations, process technology or recycling systems, and needs further strengthening research. And standard.

Experts suggest that the establishment of transparent and smooth waste power lithium battery recycling networks, changing existing payment business recycling models, adopting Japanese countries such as recycling processing methods, thereby facilitating 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 high-efficiency short-range implementation classification is discussed 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.
