With more and more environmental issues, new energy vehicles are constantly being promoted in more countries. However, it is worth noting that as an important part of the new energy vehicle industry chain, the development of the dynamic lithium battery development in improved performance, the exploration of recycling and reuse modes has become an incompetent issue. It should be studied early in the early days, and my country's constant air pollution has caused high concern from the people and the relevant state departments.

In this regard, the relevant experts said that future countries may further increase policy support for new energy vehicles. Once the electric vehicle market is launched, the power lithium battery market will bring out the explosive rise. It is understood that my country's dynamic lithium battery research is intended to improve its safety performance and service life, but the recycling link is severely detached.

For example, as the lithium ion battery of the power lithium battery contains heavy metal elements such as mercury, cadmium, lead, etc., but its positive and negative electrode materials, electrolyte solutions and other substances have a great impact on the environment. There are research institutions to predict that as electric vehicles have a comprehensive climb, it will be in short supply to Lithium 2017.

Therefore, it should be made to study the recycling of power lithium batteries as early as possible. Many people understand that the high price of dynamic lithium battery is one of the important factors currently restricting electric vehicle promotion. Relevant information shows that the power lithium-ion battery life is about 20 years, but it is only 3 to 5 years used for automobile power.

Due to the following 80% or less of its capacity to 80%, the battery life will be significantly reduced, but these batteries still have large use value for energy storage systems. According to "Energy Saving and New Energy Automotive Industry Development Plan (2011 ~ 2020)", establishing a dynamic lithium battery step utilization and recycling management system should be a feasible choice. For example, the battery with a capacity below 80% is retracted from the electric vehicle, and can continue to be used for the power source, or as a power source such as a low-speed vehicle such as electric venue.

The batteries that have been eliminated from the energy storage device or low-speed electric vehicle may have other third, fourth time. Such step-by-step utilization can make the value of the power lithium battery to achieve a full play, reducing the cost of reducing the battery in the car usage, driving electric vehicle in advance. Recycling may be the future competition main battlefield, according to the expert Li Yuko of my country Automobile Technology Research Center, it is expected that the total amount of powerful drainage of the power lithium battery is about 2 to 40,000 tons, until 2020, my country is only pure electric (including plugging) ) Passenger car and hybrid passenger vehicle power lithium battery accumulated scrap volume will reach 12 to 170,000 tons.

According to reports, the important recycling object of nickel-hydrogen power lithium batteries is nickel, cobalt and rare earth elements, and the recovery technology process is mature; copper, aluminum, nickel and cobalt in lithium ion batteries are important recycled objects. At present, the three-element positive electrode material in various positive electrode materials in lithium-ion batteries is the highest value, lithium iron phosphate, lithium manganate, and the lithium-ion battery recovery process is higher. The reporter learned that the technical route for recycling batteries is more complicated, such as in the processing of waste lithium ion batteries, first to pretreat, including discharge, disassembly, crushing, sorting, sorted plastic and iron housings Recycling; then the electrode material is leached, acid immersion, additional extraction.

Despite the high economic performance of the power lithium battery recovery, as the application scale expands, the resources are gradually exhausted, and the recycling link will show great value. Perhaps the important place to promote the competition in the future is no longer a lithium resource mining, but recycling. From the current situation of Europe and the United States, related manufacturers are vigorously promoting the recycling research of dynamic lithium battery, and technical reserves for large-scale commercial recycling.

For example, Belgian Jimei Company has developed ultra-high temperature technology to handle waste lithium-ion batteries. Toyota Motors cooperates with Qimei Copping to recycle two Toyota car lithium-ion batteries. US TOXCO has become unactivated in liquid nitrogen in liquid nitrogen environments, and then disassembles the material to isolate the battery.

Even the Germany of the powerful lithium battery manufacturer is also attached to the construction of the recycling network system. The recycling market has not yet formed, and my country has a movement in this regard, but it is not very moving. "Energy Saving and New Energy Automotive Industry Development Plan" clearly proposed that it is necessary to formulate the recycling management method of power lithium battery, set the powerful lithium battery recovery and regeneration company access conditions.

It is understood that my country's dynamic lithium battery recovery work does not match the development of new energy vehicles, and the recycling market has not been formed. Due to the my country Automotive Technology Research Center, since the new energy vehicle is in the R & D promotion stage, there is no wide range of use, so my country's vehicle power lithium battery has not had a large scale of scrap, so my country has not yet established professional vehicle power Lithium battery recycling system. However, from the perspective of recovery treatment technology, the automobile power lithium battery and the recovery route of nickel-hydrogen, nickel-cadmium, and lithium-ion batteries in the consumer electronics are basically the same, and it is important to extract valuable metal such as nickel, cobalt, rare earth elements.

At present, there is basically a corresponding recovery process in China. Li Yuko said that there is a certain number of nickel-hydrogen, lithium-ion batteries and cobalt-nickel regeneration companies in China. The recycling service network has gradually expanded.

It has recovered and regenerated the basis of the driving power lithium battery. In the future, it should be effectively utilized and improved existing existing The recycling network makes it more suitable for the recycling of large batteries in the relatively concentrated resource of the vehicle power lithium battery. Li Yumei also suggested that when establishing my country's vehicle power lithium battery recovery system, it should be based on several principles: First, we must implement the production of responsible extension system; second, the company's implementation qualification for the company's driving power lithium battery; again It is a detailed non-ferrous metal regeneration technology standard, clear nickel, cobalt, etc.

Admission qualification, encourage high-level professional regeneration company development. The reporter also learned that 50 pure electric bus batteries in Beijing during the 2008 Olympic Games have recently scrapped, how to deal with the battery that is still in front of it, becomes a problem that is resolved.
