How to land on dynamic lithium-ion batteries?

Power lithium-ion battery recycling, it has become a major focus of politics, production, research, and use four parties. Can this issue successfully resolved, will directly be related to my country's new energy vehicle promotion goals smoothly, and it is also related to new Energy, especially pure electric cars maintain its strategic status in my country's energy revolution. As early as 2006, the Ministry of Industry and Information Technology, the Ministry of Science and Technology and the Ministry of Science and Technology and the original State Environmental Protection Bureau jointly introduced the "Car Product Recycling Technology Policy" provisions, clearly proposing electric vehicles (including hybrid vehicles, etc.

) production companies should be responsible for recycling, handling their sales The battery on the car, and requires hazardous waste such as waste batteries to the qualified company for processing. This is also a policy and regulation of my country's earlier on electric vehicle scrap batteries. In December 2014, the Ministry of Finance and other four ministries issued a notice of joint issuance of 2016-2020 new energy vehicles (Draft) ", which clarified the automotive production company as a power lithium-ion battery recycling The subject of responsibility, responsible for the recycling of the dynamic lithium-ion battery.

In December 2016, the Ministry of Industry and Information Technology has organized the "Interim Measures for the Administration of New Energy Automobile Power Battery Recycling" (Draft for Comment). Clearly encourage the automobile production company, battery production company, recycling dismantling company and comprehensive utilization company, etc. In the early February 2017, the Ministry of Industry and Information Technology, the Ministry of Commerce, and the Ministry of Science and Technology jointly announced the "Guidance Opinions on Accelerating the Development of Recycling Resources".

Utilization of standard system, promoting waste dynamic lithium-ion battery regions. A series of policies have been introduced to reflect the importance of the national level of recycling of dynamic lithium-ion batteries. If the 2006 "Car Product Recycling Technology Policy" is only the "not raising" recovered by the power lithium-ion battery, then the "guidance on accelerating the development of renewable resource industry" after 11 years is calculated to be powered.

System deployment of ion battery recycling. However, in the actual operation, the recycling of dynamic lithium-ion batteries did not truly realize "industrialization" landing. It is not difficult to see by analyzing that the first is the responsible subject.

Among the above policies, the responsible subjects of the dynamic lithium-ion battery recycling were automotive production, but many new energy vehicles did not truly assume the responsibility of the "subject", one of the important causes is the first batch of new sales. Energy car, its power lithium-ion battery has not yet entered a large scale scrap period. There is no practical application, everything is "paper talk".

Despite the current Northern Automobile New Energy, Changjiang Automobile, etc. began to launch a powerful lithium battery recycling, but the number of recovered batteries is less, it is difficult to form industrialization related experience, which allows the company's recycling layout looks still in "ideal". stage.

Despite this, many ideas still "look beautiful". Such as Beiqi New Energy Plan uses its 312 built in 2020 throughout the country's independent new energy vehicle sales, service network, and promotes the regulation of retired dynamic lithium-ion batteries through consumer service policy, and is based on change taxi , Practical power lithium-ion battery shift electricity, maintenance, testing, and ladder utilization full life cycle operation mode. Who is producing, who is responsible.

In the case of the end, the main body of the power lithium-ion battery is a vehicle company, but truly recycling is not the strength of the vehicle company. And as a battery provider's power lithium-ion battery production company, in this regard, it seems to be responsible for. In fact, battery companies have more specific recycling roads than vehicle companies.

BYD with a circular industry chain is both battery production and a whole vehicle manufacturer, which has a natural advantage in the recycling of dynamic lithium-ion battery, so the layout is also earlier. To this end, BYD established a special recycled detection system, recovered from the battery to screen detection, and the ladder utilization, and the final dismantling recovery can be carried out in the own or cooperative factory, the power lithium ion battery recovery chain is basically formed, Supply beneficial reference for other company layout dynamic lithium ion batteries. In addition, CATL, Guoxuan Haoke, China Airlines, China Aviation Lithium Electric, Watma, Bike and other well-known battery production companies also realized a complete layout in the recycling of dynamic lithium-ion battery, after recovering their own products, the ladder is utilized Distributed energy storage or small power system, shipped to battery recycling company for disassembly.

However, the internal circulation chain layout within this company is always "singles alone", a battery factory's recycling model for one or more vehicle plants, and has a hundred household vehicles and battery plants in China, and follow-up "GWH" is calculated by the unit, and it will not be from the heart. How to form a valuable recycling industry chain in the industrial chain, is worth the vehicle, battery, recycling company, seriously considering. In this regard, some companies have a beneficial attempt to open a new idea for us.

Chaowei Group is not long, but its design-developed 48 volt "once electric standard module", which solves the consistency problem of the ladder, by standardized battery pack, instead of consistency problems The battery makes the subsequent tradder easy to use easier. At the same time, the Chaowei Group also proposed the form of the third-party battery after-sales service platform, promoting the contest of the market and the ladder utilization, through a third-party company, will link the vehicle and the battery factory together, and supplied by a third-party company Battery maintenance service and subsequent recycling processing, integrate the front end of the recovery chain to ensure the reliability of the recycling battery source. Despite the "mode of service-to-service recycling mode" in the superworthy group, it is also trying to explore, but the idea of ​​all upstream and downstream, let us see the possible chain of the dynamic lithium-ion battery to form an industrial value chain.

However, in the eyes of scholars, the value chain is only one aspect, and more important is how to return to the original intention - green environmental protection. In a lithium ion battery recovery method, there is currently a wet process in China, that is, the lithium-ion battery has different treatment in an acid solution, thereby extracting different metal elements. However, the traditional wet process is limited due to the limited element extraction, and the waste solution tends to have new pollution in the environment, and the relevant harmless treatment will also spend higher cost.

How to make lithium electric recycling more environmentally friendly, more economical, and some domestic research institutions have tried. Professor of Jiangxi University of Technology, Professor Tsinghua University, Xu Shengming, proposed, to maximize the various elements in waste lithium ion batteries by adding more advanced preparation processes, and taking more advanced preparation processes. While reducing subsequent contamination, the high value-added recovery materials are obtained, and the economics is improved; the researcher of the Ecological Environment Research Center of the Chinese Academy of Sciences Zhang Fu Shen believes that by mechanical chemical activation method, using mechanical energy to induce chemical reactions, it can effectively reduce the chemical substance of the recovery process.

The pollution caused, and it is more likely to achieve batch treatment; Li Lili, professor of Beijing Institute of Technology, said that if natural organic acid replaces the existing acid solution, it will be more green. The original intention of the dynamic lithium-ion battery is green and environmentally friendly, resource reuse, and the key to the company is willing to participate in it is economical. We believe that consumers will no longer emerge in government departments, research institutions and industrial chain companies.

Due to worried that the battery cannot be effectively recovering, environmental pollution is caused, and the dilemma of electric vehicles. .
