New energy vehicles are widely used in urban transportation areas due to their low displacement and small air pollution. Since this year, the state has blended a series of supporting policy support, new energy automobile development enters an outbreak period. According to the website of the Ministry of Industry and Information Technology, according to the number of certified number of passengers from the motor vehicle, in September 2015, my country's new energy vehicle produced 32,800 vehicles, 2 times higher than the year-on-year.
Xiao Yi, a new energy industry researcher Xiao letter in my country, said that the reason for the promotion of new energy vehicles is important, on the one hand, the new energy car is low, and the new energy company is driving 100 kilometers. As long as 4.3 yuan, and the traditional car is 100 kilometers but it has to be about 52 yuan.
This is because the power cost is lower than the gasoline cost, and the promotion of new energy vehicles also helps to achieve a variety of energy structures. The traditional energy is mainly Development, guarantee my country's energy security; on the other hand, due to the high environmental protection of new energy vehicles, it is important to drive, no exhaust gas emissions. Although these ideas and starting points are good for society, as the sales of new energy vehicles have skyrocketed, the problem that the dynamic lithium-ion battery has become more and more prominent.
According to relevant information, the life of the dynamic lithium-ion battery is about 20 years. Once used in the car, after 3-5 years, it must be scrapped. According to industry experts, this year, our national dynamic lithium-ion battery has accumulated approximately 20,000 -40,000 tons, until 2020, my country only pure electric passenger cars and hybrid passenger cars accumulated the volume of waste, Will exceed 150,000 tons, reaching 1.
70,000 tons of scale. If these batteries are not recycled and treated in time, they will cause secondary pollution to the Earth, and environmental issues will become more serious. In this case, recycling and reuse of new energy vehicle power lithium ion batteries have become a top priority.
Zhuo Chuang New Energy Car Analysts Benbin tells reporters: "At present, new energy vehicles have important battery types with lead acid batteries, nickel-cadmium batteries, lithium-ion batteries, lithium iron phosphate ion batteries, fuel power lithium batteries. The lead-acid battery is a relatively mature technique because of its low cost, and it is possible to discharge high-magnification. The lead-acid battery of the low-end car is not a small number, and the recovery is not a problem, but the other batteries are currently not well recycling, and the battery recycling of new energy vehicles will restrict development.
However, with the development of the industry, these recycling issues or will also be resolved, as the progress of the core battery technology that restricts the development of new energy vehicles. "But she also pointed out that the technical route for recycling dynamic lithium-ion batteries is very complicated. Most countries have not yet established recycling systems, including Europe and the United States.
The lithium-ion battery also contains a toxic substance such as lithium hexafluorophosphate. It will cause severe pollution, cobalt, manganese, copper, etc. Unlike the waste battery, the structure of the lithium-ion battery is complex, the specifications are different, and the recycling is relatively large.
Waste lithium-ion battery recovery process is complex, different manufacturers of lithium-ion battery materials, formulations are different. In addition, it is difficult to directly recover the material and the high-negative electrode material, and it is difficult to show direct business value. Because of the process of processing, the entire program is more cumbersome, and the cost is high, which makes many recycling companies.
In addition, the reporter also found that my country has no special legislation for the recycling treatment of the vehicle power lithium-ion battery, and the legal supervision is blank. In this regard, Xiao Letters pointed out that my country needs to establish special legislation for the recycling processing of car power lithium-ion battery. The improvement of the dynamic lithium-ion battery recycling system is important to the promotion of electric vehicles.
On the one hand, it is possible to help solve potential environmental crises, special legislation and norms will make certain constraints to the industry, prevent the industry's disorder, like The lead-acid battery has the same recycling, mostly in the hands of small workshops, causing pollution and waste; on the other hand, convenient consumers to handle power lithium-ion batteries. Power lithium-ion battery recovery is an important part of electric vehicle development. If the relevant law lags, it will cause a large obstacle to electric vehicles, which is not conducive to the popularity of electric vehicles.
The recycling and utilization of the dynamic lithium-ion battery should not be a restrictive factor for the development of new energy vehicles. In addition to better research and development in terms of improving their safety performance and service life, my country should pay more attention to mercury, cadmium in used batteries. Lead and other large amounts of toxic metal elements are recycled, so as not to cause secondary pollution to the environment.
On the other hand, it is also very necessary to establish a sound and improved recycling system as soon as possible. Only very well solving the recycling problem, the new energy vehicle power lithium-ion battery climbing year by year will not be a new pollution problem for Earth ecology. .
