On November 2, 2016, China Electric Vehicles 100 People's Association convened a domestic power battery industry chain related company to hold a "Power Battery Materials and Materials Comprehensive Utilization Seminar", which is a project of the 100-member society on "Power Battery Technology Upgrade and Industry Chain Research" The second seminar focused on the topic of comprehensive utilization of power battery materials and materials. At the meeting, Wang Fang, chief expert of China Automotive Technology Research Center and director of the new energy room, made a report on “Power Battery Recycling Mode Based on Full Life Cycle Monitoring”. The details are as follows:

“Power battery recycling model based on full life cycle monitoring” is a very framework thing. Some of the content mentioned here will also involve a very important piece, and also the stage of the topic material discussed today, which is the last. The stage of recycling and reuse is also of particular concern to me. It is also something that I want to learn more, so it is also a place for everyone to learn today.

My report mainly consists of several aspects, drivers, legal policies, regulatory conditions, standards system, experience accumulation, road planning, and goal outlook.

First, the driving factor. Speak two:

The first driving force is the pressure of the environment and resources. In 2015, the sales volume reached 380,000 units. At the end of 2015, it was the quantity of 500,000 units. By 2020, our plan was to sell 2 million units. By that time, we measured it. We calculated it once and calculated it. Ten thousand tons of this order of magnitude.

The result is a bottleneck of some rare resources, some pollution of the waste battery environment, and the safety of the waste battery on the shelf or the storage on the car, so this is also from the perspective of environment and resources. One reason to consider recycling must be considered.

In fact, we have also communicated with the material factory. For example, companies such as Betray are also very direct in their recycling. We must consider that one is the environment, and the other most importantly, apart from mining, we want to The way to get the raw materials is necessary to carry out such recycling work.

The second driving force is the pressure on the cost of nuclear power batteries for electric vehicles. We know that the current electric vehicle requires a capacity reduction of less than 80%, which is considered to be out of the scope of the power battery, that is, the end of life. In fact, we can look at it. If we look at this area, we know that the energy available for the power battery at this stage is about 36%. If this time directly enters the recycling stage, its cost of use is the life of the battery. The cost of the cycle is very limited.

We hope that 64% of the energy is wasted, probably only an intuitive number. Of course, if we recycle from materials and then return to the power battery, there is still a certain value of this use. Because everyone also saw that the "2020 Plan", including the "2025 Technology Roadmap" and so on, also mentioned that, for example, the cost of the battery in 2020 should reach 8 cents / watt hour, I think in the cascade The use of even recycled raw materials and back to the power battery, such a process will also greatly affect the cost of our entire power battery life cycle cost reduction, so it is also the two driving forces.

Therefore, from the perspective of resource conservation, from the perspective of protecting the environment, and from the perspective of eliminating hidden dangers, the entire cascade utilization and recycling must be done. In fact, I have said before. What is the purpose of our electric vehicles? We are from the perspective of energy conservation and environmental protection. We cannot hope that in the next 10 or 20 years, or our children and grandchildren will live in all waste batteries. It is all in the environment of abandoned electric vehicles, so it is imperative that we do this work. Of course, some people have considered that these economic factors and other factors, I think there can be many breakthroughs in the process of continuous technological development.

Second, legal policy. From the legal point of view, including the "Environmental Protection Law", "Clean Production Promotion Law", "Activities for the Prevention and Control of Environmental Pollution by Solid Wastes", it provides for macroscopic requirements for the prevention and control of environmental pollution and the clean production of enterprises. In addition, in some important outlines, such as the "2020 Plan" and the "Guiding Opinions on Accelerating New Energy Vehicles", it is also clearly proposed to establish a system for power battery management of electric vehicles.

Several ministries and commissions also issued the "Automotive Product Recycling Technology Policy", which also gives the approximate requirements. Starting from this policy, in fact, the Ministry of Industry and Information Technology also began to formulate the industry standard management conditions for power storage batteries last year, which is the standardized management conditions for comprehensive utilization. Everyone has seen the standard conditions on the left. Everyone knows that there is a service in the after-sales service. The power battery system enterprises must have recycling channels, and such channels must be established.

In the "Industry Standards and Conditions for Comprehensive Utilization of Power Batteries" issued by the Ministry of Industry and Information Technology in February this year, the requirements of these six aspects are also stipulated. I would like to highlight the third article on comprehensive utilization of resources. What is its concept? It mainly includes the use of cascades, the recycling of resources, and the energy recycling of raw materials.

After that, we started the drafting and weaving of the interim measures. A basic principle of the interim measures is to implement the system of extending production responsibility. The concept of adhering to the product life cycle begins here as a standard for the power battery coding system. In order to make the power battery products reliable, the traceable, and the entire node controllable to achieve such a purpose. At the same time, it also mentions such a proposal to encourage the combination of production, learning and research, and the innovation and demonstration of various recycling and reuse models.

Standard system, just mentioned by Director Xiao, there is a relatively complete standard system for power battery recycling. Two of the standards have been approved, four standards are being drafted, and some standards are being drafted. The formulation of the previous code is being sought online, and will be submitted for approval at the beginning of this year.

The accumulation of experience is mainly to mention that the cascades are actually not a lot of ladder demonstrations. The Mitsubishi Corporation of Japan has mainly done such a demonstration project, which mainly uses batteries that have been eliminated from Mitsubishi Motors and the logo Citroen. , a demonstration study of power storage. The US DOE has support for such national laboratories to start secondary battery utilization projects, but most of them are published on the level of a combination of some laboratory simulations and small energy storage power stations.

In 2012, China's State Grid had such a project, "Technology Research and Demonstration of Electric Vehicle Power Battery Cascade Utilization", and a demonstration line was established in Beijing during the research process of this project. Henan Province has built a hybrid microgrid cascade utilization application project. Jiangxi Power Grid has established a demonstration project of 100 kWh of wind and light energy storage. Here we have also done some work, mainly to study some of its health status from the power battery, from the electric car to the second use, and some analysis of its later life and economic benefits.

We also summarized and analyzed some of the current status, including some previous experiences and some current research results. I feel that there are still some difficulties or disadvantages in the use of cascades.

First, the market mechanism is not perfect, and the policies and regulations are not perfect.

Second, the lack of historical data.

Third, the uncertainty of the cascade utilization scenario.

Fourth, the difficulty of battery disassembly and the high cost and high risk of reorganization.

Fifth, the increase in safety risks after the use of cascades.

In response to this, because in fact, after we finished the project, we did not do this in depth for a while, but also because of so many difficulties, but since we restarted to do this project, considering these issues, we also put forward some solutions. The plan, including the lack of some historical data, is also because the power battery coding system has been written and can be released immediately, so that we can have a fully operational database of power batteries.

Second, the battery module standards are not uniform. Just mentioned the difficulty of using cascades, and now the standardization standards for modules are also being done.

Third, the performance life is uncertain, we hope to have one, as mentioned in my PPT topic today, is the monitoring system that can be used throughout the life cycle. We hope to put this evaluation and monitoring process on the whole use of the battery. During the cycle, instead of eliminating the battery, it will be tested and screened. So we have to evaluate its health status in real time so that we can know the state of security after it ages.

This is our overall route plan. I also hope that you can make some corresponding suggestions, because we have also cooperated with some enterprises to carry out corresponding work. We know that the full life cycle of power batteries, including initial production and first use, that is to say in electric vehicles, it also includes its monitoring and evaluation, to re-integration, to the second use and recycling.

Let's take a look at the first stage, the stage of production and reuse, which is the stage of the first use. We need to have a running monitoring system on the electric car. That is to say, I just mentioned that the coding system of our power battery is already there. This time, when the battery is used from the time of production to the use of electric vehicles, we already have an ID card. We can know its physical condition and all its information.

The data obtained by the monitoring system has such characteristics, its implementation, its uniqueness and its comprehensiveness, as well as its full-tracking characteristics. In the second stage, the evaluation of the state of health, that is, what I just said, the whole process of monitoring, what kind of concept is it? The first monitoring system in front was to give the battery an ID card and to know the status of all its activities.

The evaluation of the second state of health is equivalent to a health care hospital or a health care center behind the battery. Together with us, we can get the real-time health status of the battery, and the health status indicator wants to use it in the ladder. There may also be an intermediate integration process.

The integration process does not have to be disassembled and utilized like the one shown above. If so, what do we need to do?

What needs to be considered is the state of the scene of later reuse, including high-end areas, such as energy storage, etc., including low-end types, such as household energy storage, which is very simple, including the stage of recycling. . What we may need to consider is the state of the actual working condition corresponding to each application field. The parameters corresponding to this working condition, such as its energy requirement, its power requirement, and our parameter values. They are all lost in this evaluation system.

At this time, because the health status evaluation system can know in real time what the state of the battery is, that is, what is the state of the battery on the electric car. At this time, we can according to the index parameters of these fields that may be used in your system in the future. To match, in real time, it can be displayed whether the health status of each battery module belongs to the available field A, field B or field C, or whether the battery has been attenuated until it can directly enter the material recovery stage, so this Is such a number we want to get.

Through such a stage, it is relatively simple to re-group integration. We believe that most of the re-group integration is still at the module level, rather than to the single unit, so the cost of disassembly and re-integration is Too high. Of course, we also talked with some companies before, he also has a way to reuse the monomer, that is to say, his monomer is relatively easy to disassemble, and after the disassembly, left the hole of the secondary injection, the battery twice The life, used in the field of electric bicycles, is also a model that I think can be explored.

The most important part is that after the so-called battery ID card, the health care hospital behind it can always match the health assessment and the scene, and know at any time which batteries can enter the secondary use field. .

In short, this cascade utilization, as mentioned by Director Xiao just now, is very complicated and difficult. It also involves many fields and industries, including its production to the use of cars, and then similar to electricity. Energy storage, including household energy storage, electric bicycles, etc., to the recycling of materials, recycling of raw materials, and the quality requirements of these raw materials, can return to our power battery industry.

Therefore, this also requires cooperation across various industries. It also requires coordination and cooperation in several aspects of policies and standards. I hope that we can pass such an attempt, because these projects have already started, and can be formed in 3-5 years. Such a closed-loop cycle of replication, such a closed-loop mode of the entire illness cycle.
