With the outbreak of new energy vehicles, the amount of powerful lithium battery will be ushered in a small peak. my country's automobile technology research center predicts that in 2020, my country's automobile power lithium battery accumulated scrap volume will reach 120,000-17 million tons. In fact, the batteries that cannot be used by electric vehicles can not be used, not to say, there is no use value.

For example, the life of the lithium-ion battery is about 20 years, but when used for automobiles, the battery capacity is generally attenuated to 80% of the initial capacity, and the battery capacity will be significantly reduced. The power lithium battery will be replaced. These scrapped batteries on electric vehicles can be used in accordance with battery capacity, and they are used in the energy storage or related power supply base station and the street light, and the low-speed electric car will finally enter the recycling system.

This is also the industry's own power lithium battery reuse or step utilization. my country's energy report has reported that many industry insiders believe that considering the strong development trend of future electric vehicles will bring power lithium battery cladding to the blue sea. However, there are also industry insiders, the idea of ​​power lithium battery steps is very good, there is still a lot of problems in actual operation.

For example, when the scrap dynamic lithium battery is used by the step, the gap is large due to the consistency of the battery, which causes a big obstacle to group use. At the same time, when the battery capacity, voltage, etc., when the step is utilized, it will form a breakfall in the number of cycles, which causes great difficulties on the later use.

In addition, including national grids, local governments, battery companies and institutions have carried out research on dynamic lithium battery ladder, although they have made certain progress, but currently in the exploration stage, there is no system industry chain. All countries in the world are actively carrying out experimental research and engineering applications of dynamic lithium battery ladder, including countries such as US, Germany and Japan, have already had a successful engineering and commercial project. The United States is more comprehensive for dynamic lithium battery steps, and its systematic research is made in terms of economic benefits, technology and business feasibility analysis of dynamic lithium batteries.

Currently, the United States has 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 five-set Chevrolet Volt Wolka battery, you can support 3-5 US ordinary families in electricity 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 peak 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, Germany has established a relatively complete recycling legal system, according to Germany, according to the provisions of battery recovery regulations: in Germany, battery production and importers must register in government, dealers must organize the retraction mechanism, and users have obligations to waste Battery is given to the designated recycling mechanism. This production person's responsibility extension system is implemented and established a complete battery recovery system.

At the same time, the German Environment Department funded two dynamic lithium battery recycling demonstration projects (Libri projects and lithorec projects), study resource utilization for waste dynamic lithium batteries. As early as 2010, the 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, providing a good specification for the recycling of power lithium batteries.

Previously, Japanese battery manufacturers established a battery recovery system for battery production and sales recycling. In terms of dynamic lithium battery steps, Nissan cars established 4Renergy companies before listening to the Sumitomo Group before listed, and important car discarding batteries. Currently, the scrapped battery of Nissan Harmon Car in Japan and the United States can serve as a residential and commercial energy storage equipment.

More than the current situation of battery recovery in several countries can be seen that in addition to the advanced power lithium battery recycling technology, these countries also have relatively sound legal regulations. At present, in order to guide and promote dynamic lithium battery steps, the national policy level is continuously introduced, but my country has lacks professional laws and regulations, and the recycling company has lacks relevant strict management system. Therefore, there is also a need to learn from foreign related experience to establish a complete set of powerful lithium battery recycling systems.
