Talking about the three weights of the lithium battery recycling: more virtue days

my country's energy storage network: under the guidance and promotion of national policies, the output and protection of new energy vehicles continue to rise. As, the power lithium-ion battery will reach a small peak of the scrapped in 2020. According to the data of my country's Automotive Technology Research Center, the amount of power of the dynamic lithium-ion battery will reach 320,000 tons in 2020.

It can be seen that how to dispose of scrapped cells has become a problem that is not unpredictable, it can be said to be very urgent. In the 3rd my country Lithium Industry International Summit Forum, Professor, Central South University, summed up the three need for dynamic lithium-ion battery recycling: First, everyone is very understood, there is high pressure direct current, There is a risk of burning explosion. Second, pollution problems Although the lithium ion dynamic lithium ion battery is contaminated with lead-acid batteries, there is also phosphorus, cobalt, nickel, etc.

, which can be said that the pollution is more complicated than lead acid batteries. For those who engage in metallurgy, the recovery process of lead-acid batteries may be simpler, but the lithium-ion battery is very difficult. The country's wastewater, exhaust gas indicators, heavy metal cobalt and nickel national standards are 0.

5 mg / liter. Third, the resource problem In fact, our country's cobalt resources are very lack of, 95% of the cobalt dependence on the country should be highly valued. It should be said that 70% of oil is so nervous, 95% should be more nervous? This is also like this, and the lithium is more than cobalt, but 70% of lithium is also a large proportion.

According to the 2016 data, there have been more than 500,000 electric vehicles, and the national policy - from 2020 to about 10%, the amount is about 4 times, if the dosage is over 4 times, our cobalt, lithium Turn 4 times? Dynamic lithium-ion battery recycling is safe, polluting, resource issues, but also affects the sustainable development of new energy vehicles. Global countries are actively carrying out experimental research and engineering applications of dynamic lithium-ion batteries, including countries such as US, Germany and Japan, and have some successful application of engineering and commercial projects, United States, USA to dynamic lithium-ion batteries The step utilization research is more comprehensive, and the systematic research is made in terms of the economic benefits, technology and business feasibility analysis of the power lithium-ion battery. The current application of related demonstration projects and business operations projects.

For example, in 2011, General Motors and ABB begin to collaborate how to use Chevrolet Volt Wollanda's battery pack to collect electrical energy feedback power grids, and ultimately achieve household and commercial power. After trying to re-integrate the Volt Wolka battery used by the five groups to a modular device, support 3-5 US ordinary family two-hour electric supply. In the future, similar applications will be able to supply spare electricity at some families and small commercial buildings.

At the same time, in the high-performance period of the electricity price period, it is also possible to make up for the gap in wind power, photoelectric or other renewable energy power generation. At the same time, the US government also promotes the establishment of battery recycling network. It takes an additional environmental fee, and pays a certain amount of handling fee when consumers purchase batteries, and the battery production company has funded a part of the recovery fee for the recovery of the battery.

Germany is currently, Germany has established a relatively complete recycling legal system. According to the provisions of the Battery Recycling Regulations in Germany: In Germany, battery production and importers must register in the government, dealers must organize the recycling mechanism, and the user is obliged to hand over the used recycling institution. This production and implementation and implementation of the production and implementation of the battery recycling system.

At the same time, the German Environment has funded two dynamic lithium-ion battery recycling demonstration projects (Libri projects and Lithorec projects), and conduct resource utilization of waste dynamic lithium-ion batteries. As early in 2010, TUV Nadee will group was commissioned by Germanyfederalinstitute, participated in the research project of electric vehicle battery ladder utilization. The project plans to establish an energy storage application demonstration project in Berlin, Germany, and get funding for German energy and climate research institutions.

In addition, Germany Bosch Group also uses BMW's Activee and I3 pure electric car scrapped battery to build 2MW / 2MWH large photovoltaic power storage system. Japan's neighboring countries are also better in countries with recycling in waste batteries. Japan's sound circular economy development laws and regulations system, the recycling of dynamic lithium-ion batteries supply good specifications.

Previously, Japanese battery manufacturers established a battery recycling system for "battery production sales - recycling-regenerative treatment". In terms of dynamic lithium-ion batteries, Nissan cars have established 4Renergy companies in the "Hearing Wind" listed before the listing of Sumitomo Group, and the reuse of electric vehicles is engaged in electric vehicles. Currently, the scrapped battery of Nissan Harmon Car in Japan and the United States can serve as a residential and commercial energy storage equipment.

Comparing the status of battery recovery in the above countries, these countries also have relatively sound laws and regulations in addition to the advanced power lithium-ion battery recycling technology. At present, in order to guide and promote dynamic lithium-ion battery steps, the national policy level is continuously issued, but my country has lacks professional laws and regulations, and the recycling company has lacks relevant strict management system. Therefore, my country must also learn from foreign related related experience to establish a complete set of dynamic lithium-ion battery recycling systems.
