Dynamic lithium battery recycling industry encounters 4 "blocking road tigers"

The new energy vehicle has developed rapidly under the double support of the national and market. As of the end of 2017, my country's new energy vehicle sales have reached 1.8 million, and more than 50% of global accumulated sales.

The power lithium-ion battery is used as the root cause of the new energy vehicle source, and it has developed rapidly. Data show that in 2017, my country's powered lithium-ion battery production was 44.5GWh, up 44% year-on-year.

In 2017, my country's powered lithium-ion battery output value was 72.5 billion yuan, up 12% year-on-year. With the continuous improvement of my country's dynamic lithium-ion battery production, the battery retirement of the power will also gradually scale.

After the vehicle power lithium-ion battery is retired, it is necessary to consider the problem of recycling and reuse. So what happens during the recovery process? 1. Dynamic lithium-ion battery manufacturing and process is complex, dismantling difficulty high power lithium ion battery for recycling, first of all, it is to be disassembled, but there is a variety of different power lithium-ion batteries on the market.

In the new version of the electric vehicle terminology, the battery is divided into three types, including cylindrical batteries, square batteries, and soft bag batteries, and more. Each type of power lithium-ion battery has its complex manufacturing technology and process design, so it is impossible to automate it in the dismantling process. This means that in the case where the level of automation is not high, the dismantling process should be done by manually, and each worker's technical level is not uniform, and the technical level that does not have a uniform technology is not uniform, dismantled.

The difficulty can be said to be very high. In the dismantling process, once there is a mistake, pollution or security issues may occur, and these two problems are very dangerous. 2.

The recycled battery quality is not uniform, and the processing technology is lacking according to the industry standard. When the battery capacity is attenuated to 80% of the rated capacity, the power lithium-ion battery does not apply to electric cars, and the ladder is taken. When the battery capacity is attenuated to 20% or less of the rated capacity, the disassembly recovery is required.

During the recovery, the quality of each power lithium-ion battery is different, and the retained data is not necessarily complete. This is necessary to perform specific detection, which is undoubtedly the cost of the new recovery process. Also, the internal resistance, electrochemical characteristics, thermal characteristics of different batteries are different, and the inconsistency and reliability of the battery cannot be guaranteed.

In addition, there is a problem with the battery, but it will give each recycling after it. Process brings security risks. In addition, although the ladder use is an effective recycling means that it can theoretically use the battery on electric vehicles, which can be used in the field of solar energy and wind energy power systems, energy storage power stations, mobile base stations, low-speed electric vehicles.

However, my country's technology is still very lacking in the practical application of engineering, recycling and re-resource process. 3. The battery recovery cost is high, and the economic benefits are generally high in the domestic market.

The output value of the dynamic lithium-ion battery is high, but the economic benefits brought about by recycling are not so obvious. A company with mechanical law and wet recovery of iron-free phosphate ion batteries, recycled treatment of 1 ton of waste phosphate dynamic lithium-ion battery is 8540 yuan, while the regeneration material is only 8110 yuan, loss of 430 yuan. The reason why the dynamic lithium-ion battery recovery is not high, because most of the dynamic lithium-ion battery in the domestic market is based on lithium iron phosphate, manganate, and the price of its raw materials is compared to other power lithium ion batteries Material is low.

In addition, during the recovery process, the cost of waste and resource waste is also very high. The previous author mentioned that most of the recycled dismantling process should be manually completed due to the complexity of the manufacturing and process of dynamic lithium-ion batteries. In addition, due to the manual dismantling, it is easy to make mistakes in the process, leading to waste, new cost.

4. The recycling network has not yet been perfect, and the relevant standard penalty is not enough. It is predicted that in 2020, my country's powered lithium-ion battery scrap will exceed 248,000 tons, approximately 20 times the 2016 annual report.

In the face of the upcoming powerful lithium-ion battery recovery, my country's recycling network is not strong enough, the market has no effective recycling model, not standardized. Dynamic lithium-ion batteries are prone to resource waste, environmental pollution, etc. If these batteries recovered by a private company will then flow into the market again, they will bring safety hazards to people.

Furthermore, even if the power lithium ion battery is compliant with the prescribed related recovery company, if they do not follow the processes and standards during the recycling process, they will not be subject to what specific punishment. For the latest implementation of the "Car Power Lithium Ion Battery Recycling Sales Detection" in February 2018, it is only a standard for the dynamic lithium-ion battery recovery, but does not formulate a specific and effective reward penal. Method.

This will not be guaranteed, the relevant power lithium-ion battery recycling company can fully comply with relevant standards and regulations during the recovery process. Before the power lithium-ion battery recovery is coming, we should understand what hindrances will encounter on the recovery road. Power Lithium Ion Battery Recycling Co.

, Ltd. should also make each problem, improve the relevant technical and implementation standards, so that my country's power lithium-ion battery recovery is the safety, and the norms of the norms.
