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-ion 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-based rising rose will be brought to the power lithium-ion battery market. It is understood that there are currently important in my country's dynamic lithium-ion batteries in China to improve their safety performance and service life, but the recycling links are severely detached.
For example, as a lithium ion battery of a powered lithium-ion battery does not contain a heavy metal element such as mercury, cadmium, lead, etc., but its positive and negative electrode materials, electrolyte solutions, etc. 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-ion batteries as early as possible. Many people know that the high price of dynamic lithium-ion batteries 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% of its capacity to 80% or less, 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-ion battery step utilization and recycling management system should be a viable 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 a step-by-step utilization allows the value of the power lithium-ion battery to achieve a full play, thereby achieving the cost of reducing the battery in the automotive usage stage, driving electric vehicle in advance.
Recycling may be the future competition main battlefield, according to the expert Li Yuko of my country's Automobile Technology Research Center, it is expected that the amount of powerful lithium-ion battery accumulates about 2 to 40,000 tons. By 2020, my country is only pure electric (including plugging) Based on the multiplier and hybrid passenger vehicle power lithium ion battery accumulated scrap volume will reach 12 to 170,000 tons. According to reports, the important recycling object of nickel-hydrogen power lithium ion battery 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. Although the current energy-lithium-ion battery recovery is not high, with the expansion of the application, 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 in Europe and the United States, related manufacturers are vigorously promoting the recycling research of dynamic lithium-ion batteries, 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 dynamic lithium-ion 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 the management method of dynamic lithium-ion battery recycling management, set the power lithium-ion battery recovery and regeneration company access conditions. It is understood that my country's dynamic lithium-ion 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-ion battery has not had a large scale of scrap, so there is currently no professional car in my country. Dynamic lithium ion battery recycling system. However, from the perspective of recovery processing technology, the automobile power lithium-ion 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 nickel, cobalt, rare earth elements.
Metal, currently has basically has corresponding recovery treatment technology. Li Yuko said that there is a number of nickel-hydrogen, lithium-ion batteries and cobalt regeneration companies in China, and the recycling service network has gradually expanded. It has been recovered and regenerated to handle the basis of lithium-ion batteries of the vehicle.
There is a recycling network that makes it more suitable for the recycling of large batteries in the relatively concentrated resource of the vehicle power lithium-ion battery. Li Yumeo also suggested that when establishing a dynamic lithium-ion battery recovery system in my country, it should be based on several principles: First, we must implement the production of responsibility extension; secondly, the company's executive qualification of the company's driving power lithium-ion battery Further, it is the development of a detailed non-ferrous metal regeneration technology specification, clear nickel, cobalt, etc. Admission qualifications, 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.
