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 the interview, said that the new energy vehicle is generally promoted by countries, on the one hand, the new energy vehicle has a low cost, and the new energy company is driving 100 kilometers as long as 4.3 yuan, and the tradition The car is 100 kilometers but it is about 52 yuan, which is due to the low power cost is lower than the gasoline cost, and the promotion of new energy vehicles also helps to achieve a variety of energy structures, and the traditional energy is mainly developed to diversify development, ensuring my country's Energy security; on the other hand, due to the high environmental protection of new energy, it is important to drive, no exhaust gas discharge. Although these ideas and starting points are beneficial to society, with the skyrocket of new energy vehicles, the problem that the power of the dynamic lithium battery has increased.
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 battery has accumulated approximately 20,000 -40,000 tons.
Before and after 2020, my country only pure electric passenger cars and hybrid passenger vehicles cumulative scrap volume will Break through 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 batteries have become a top priority. Zhuo Chuang New Energy Motor Analyst 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, fuel power cells. 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 power lithium 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. Lithium-ion battery recovery process is complex, different manufacturers of lithium-ion battery materials, formulas 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 lithium battery in the car, and the legal supervision is still blank. In this regard, Xiao letter pointed out that my country needs to establish special legislation for the recycling processing of car power lithium battery.
The improvement of the dynamic lithium 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 development of disorder, like lead The same recycling of the acid battery is the same, mostly in the hands of small workshops, causing pollution and waste; on the other hand, convenient consumers can handle power lithium batteries. Power lithium battery recovery is an important part of electric vehicle development.
If the relevant law lags, it will cause great obstacles to electric vehicles, which is not conducive to the popularity of electric vehicles. The recycling and utilization of the power lithium battery should not be a restrictive factor for the development of new energy vehicles. In addition to better research and development of its safety performance and service life, my country should pay more attention to mercury, cadmium, lead in used batteries.
Waiting a large amount of toxic metal elements to recover, 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 resolved the recycling problem, the new energy vehicle power lithium battery climbing year by year does not become the new pollution problem for Earth ecology.
