  Author :Iflowpower – Portable Power Station Supplier

With the explosiveness of new energy vehicles, the power lithium-ion battery will increase rapidly, and quickly enter the scrap period. Studies have found that abandoned lithium-ion batteries contain cobalt, manganese, copper and other heavy metals, improper treatment of environment, and even endanger human health. Since my country started a new energy vehicle "Ten City Thousands" plans, 2009 to 2015 has accumulated 497,000 vehicles in new energy vehicles.

In 2015, my country's new energy vehicles were 340,500, accounting for more than 60 million outputs in the world. The amount of lithium-ion battery scrap has accumulated approximately 20,000 to 40,000 tons. Therefore, the relevant departments should be prepared, and the recycling of new energy vehicles dynamic lithium-ion batteries will be studied.

First, increase policy implementation. In 2012, "Energy Saving and New Energy Automobile Industry Development Plan" clearly requires the development of dynamic lithium-ion battery recycling management methods, dynamic lithium-ion battery step utilization and recovery management system. In January this year, the Ministry of Industry and Information reschedurate social opinion on "Normative Conditions for New Energy Automobile Waste Battery Comprehensive Utilization", which proposes normative requirements for the site selection, energy consumption control, etc.

of waste dynamic lithium-ion batteries. At the end of January, the Ministry of Industry and Information Technology, the Development and Reform Commission, the Ministry of Environmental Protection, the Ministry of Commerce, the Quality Supervision Bureau, etc. The recycling of electric vehicle power storage batteries is carried out, establishing a power battery recovery system for upstream linkage; establishing a dynamic lithium-ion battery coding system to establish a traceability system.

These are the guiding documents of new energy vehicle power lithium-ion battery recycling, must be landed as soon as possible; it is necessary to perform top-level design, overall planning, improve management efficiency due to local conditions, and promote the focus, step by step, promote waste power lithium-ion batteries resources Chemical, scale, high value utilization, standardizing industry behavior, prevention of repeated construction and overproduction. Second, promote ecological design and full life cycle management. Ecological design is also known as "design", in the full life cycle of dynamic lithium-ion battery design, production, use, scrap and recycling, reflects resource savings and efficient use, environmentally friendly; Recycling and comprehensive utilization.

To minimize the use of toxic hazardous substances, especially heavy metals. Although the lithium-ion battery is free of mercury, cadmium, lead and other heavy metal elements, but the positive and negative electrode materials, electrolyte solutions have certain effects on the ecological environment, should not be neglected. To create conditions for subsequent recycling, classification, and comprehensive utilization, such as labeled material chemical components on the battery surface or packaging material.

Considering the wear of the power lithium-ion battery in use, waste collection and transportation, etc., it is best to printed on the wear material. To drive recycling companies to enter the industrial park, strengthen management.

Recycling and utilizing the dynamic lithium-ion battery should be implemented. Introduce international advanced environmental protection equipment, realizing secondary dust removal for lead smoke, lead, etc., do 100% standard emissions.

Recycling the rainwater and sewage of the park, improve the utilization rate of the water, and do 100% of the wastewater to discharge or even zero emissions as much as possible. In accordance with ISO14000 to the environmental management requirements of the workplace, ensure that employees do not bring lead dust. Configure employee production and rest locations to ensure that there is no impact on employee health.

The third is to use the existing waste materials recycling system or network. After several large impact and adjustment system, my country's waste materials recycling system has been coexisting from the Supply and Marketing Society to the Materials and Supply and Marketing Society, and then the rapid development of Internet + renewable resource recycling is now. The Ministry of Commerce funds or integrates the recycling network of recycling resources around the country.

Some places have also formed the unity of employment access, the unification of the fixed-point management, the unity of the recycling number, the unity, the unity of clothing, the unity of health standards, account management and the unity of garbage and garbage collection, etc. The National Development and Reform Commission supports the "urban mineral" pilot, forming a corresponding recycling system. Some renewable resources such as steel, non-colored, batteries, have also formed a recycling network with the company's leading.

These have made a solid foundation for the recycling of new energy car batteries, and they should make full use and reference. Recycling of lithium ion batteries, can learn from the practice of lead-acid battery recovery system. According to the requirements of the Ministry of Commerce, the recycling pathway is added, regulating the recovery behavior of individuals and companies in the social recovery system.

With the company's recycling system, new recycling varieties, expand recycling information services. Combine the green low-carbon development trend of Internet +, create a professional recycling platform, form a new recycling system based on new energy vehicle power lithium-ion batteries. According to the spirit of the state, the retrospective of new energy vehicle power lithium-ion batteries, through quality monitoring, and utilize large data to promote the quality of dynamic lithium ion battery products.

The fourth is to innovate business model, promote the replicable circular economy development model. Waste dynamic lithium ion batteries have a variety of resources. One way is to use.

Dynamic lithium-ion batteries below 80%, can be used in other fields of electric vectors to exert their residual value. If you can be used as a power grid temper storage power station, a family energy storage power station, a company's energy storage power station, and a low-speed electric vehicle, electric bicycle company, prospects are optimistic. Waste plastics, battery packs and packaging should be as reclaimed as much as possible.

Power lithium-ion battery step utilization must take low cost as the primary consideration factor, otherwise it will fall into the difficulties of pursuing technical indicators and ignore business value, so that the operation of steps is difficult. Power lithium-ion batteries are used in the field of communication base stations, etc., which must be guaranteed in terms of security, stability, etc.

Industrial electric wave peak trough electricity price is large, if you can save electricity at night, power supply during the day, can also alleviate grid pressure, and reduce the company's electricity cost. However, on the basis of technical economic analysis and evaluation, accumulate related experience, preventing ahead. Another way is to use it as a waste to directly scrap disassemble, refine the various useful elements or raw materials, and realize the recycling of raw materials.

At present, the recycling rate of raw materials has reached more than 70%, and the lead-acid battery recovery is even more than 95%. Comprehensive utilization of waste dynamic lithium-ion batteries in technology does not have problems, important is cost control and business model development. There is a suitable market to make good economic benefits, you can minimize the value of the power lithium-ion battery and turn waste into treasure.

In the Beijing-Tianjin-Hebei area, the comprehensive utilization of the comprehensive utilization of waste batteries, teamed up with the new energy, Tianjin power, Tianjin Zhizhen and other companies to jointly carry out comprehensive utilization of dynamic lithium-ion batteries. For similar layouts, there should be a national switch to avoid blind development. The fifth is to strengthen the commonality of recycling, key technology research and development.

Overall, the technical research and development and promotion of power lithium-ion batteries, my country's recycling research on dynamic lithium-ion batteries is relatively insufficient. Given the important material of the dynamic lithium-ion battery, such as nickel, cobalt, rare earth and other resources, and the possible pollution problems that may occur in recycling of lithium-ion batteries in the scrap dynamic lithium-ion battery, and increase technology research and development is currently support, industry To consider solving problems. Improve the technical level of new energy vehicle power lithium-ion battery recycling, to carry out the production research cooperation between the company and the research institute, develop advanced applicable technology, especially the use of lithium ions.

After all, the location in the Chemical Elements in the Gameprev is determined that lithium has strong metal activity. To continuously develop disassembly and utilization techniques corresponding to fuel-powered lithium batteries, iron lithium ion batteries, lead-carbon batteries, high temperature batteries, winding batteries, supercapacitors, etc., upgrading the testing equipment, prevention and governance facilities, etc.

Add automatic monitoring system. While extracting useful elements, avoiding the unnecessary environmental pollution. To eliminate the disassembly equipment of the original waste lead-acid battery semi-machinery, enable automatic crushing sorting system.

Advanced predefinctancy processes to reduce pollutants emissions. To encourage the company to eliminate the original fuel reflection furnace, refining furnace, to achieve the new energy vehicle power lithium-ion battery recycling industry green low-carbon development. To speed up the construction of the standard system for recycling of power lithium-ion battery.

There are many kinds of lithium-ion batteries, my country's important cobalt organte, lithium manganese acid, lithium nickel-manganese acid, lithium iron phosphate, etc. The construction of the factory should also reflect energy-saving, low carbon requirements, to build a modern factory, not a simple stacking site. Six is ​​technical information related to the relevant maintenance requirements disclosure.

Due to technical maturity and stability, it is possible to detect and repair new energy vehicle power lithium-ion batteries. In reality, the recycled cells come from different manufacturers, specifications, meaning that the repair or reuse of battery packs should be disassembled according to different design methods. In addition, different models have different battery pack structural design and module connection methods, and process technology is different.

It is impossible to disassemble, repair or reuse with a disassembled flow line. If the dynamic lithium ion battery structure, technology and crafts are unfamiliar, because the residual voltage will reach hundreds of volts (excluding 18650 batteries), there will be dangerous when dismantling. The battery system is a chemical system that changes at any time, for various chemical systems, different specifications and batches, various manufacturers, and various health status of battery modules to ensure safety.

The reuse of the power lithium-ion battery should also consider the remaining life of the battery. If there is only the original data of the factory, there is no detailed record of the usage, the power lithium-ion battery is unclear, and the comprehensive utilization company will invest additional work, including testing, modeling, analysis. Despite this, the obtained data is not necessarily accurate.

Discliminating the battery module, visually inspections cannot find the safety defects, such as slight extraction, leakage, short circuit, insulation failure, two-pole corrosion, etc. In the middle, you will leave a safety hazard. Therefore, once the power lithium-ion battery should be repaired, the relevant provisions of the Ministry of Transport shall be disclosed in the relevant provisions of the Ministry of Transport, disclose the relevant technologies or crafts of maintenance.

Seven is the incentive policy for developing and performing power lithium-ion battery recycling. my country has issued a series of policy measures to promote new energy vehicles in the purchase subsidies, infrastructure and standard norms. The innovation is significantly improved, the four characteristics of the new trend of industrial integration.

2015 "Policy", the collection, classification, storage, transportation, step utilization, regeneration, supervision and management of waste dynamic lithium-ion batteries, and clear the responsible subject and vital manner, requiring the establishment of a traceability system. However, the recycling of new energy vehicles dynamic lithium-ion batteries has not yet incentive policies, and the company has not seen power lithium-ion battery recycling is a profitable thing. In the practice, the first circular economy of the first park in Anhui Tunicion attaches great importance to the circular economy of R & D, production, recycling, and the development of the "manufacturing-recycling-re-use" circular economy model, which is worth a summary and promotion.

There are a wide variety of lithium-ion batteries, complicated and have no unified standards, and retired batteries should be used, and they need to be complex by disassembly, sorting and secondary set, and dismantling process is difficult to carry out industrialization. As lithium-ion batteries are increasingly wide, recychable metal, reduce pollution caused by environment, alleviate resources, etc., have important social benefits and environmental benefits.

Dynamic lithium-ion battery recycling is not only a bottleneck that must be broken, but also one of the core issues related to the future development of new energy vehicle power lithium-ion batteries. Regarding public welfare, such as technology research and development, equipment imports, and recycling technology and equipment development, and equipment development, countries should give necessary policy incentives. Eight is to strengthen integration, promote the healthy development of new energy dynamic lithium-ion battery recycling industries.

my country's new energy automotive industry and the development of dynamic lithium-ion battery recycling industry have involved many departments. For example, the Ministry of Science and Technology support technology innovation, the National Development and Reform Commission supports the "urban mineral" pilot, the Ministry of Industry and Information Technology supports industry, especially strategic emerging industries, the Ministry of Commerce supports recycling system Construction and operation, the Ministry of Environmental Protection strictly controls environmental protection. In the development of new energy vehicle power lithium-ion batteries, integration should be strengthened and changed in the past.

Relying on the reality of low cost and large company competition, promote the healthy development of the industry to achieve the environmental protection objectives of the sky. Executive staff, deputy inspector.
