In recent years, under the guidance and promotion of national policies, my country's new energy automotive industry has developed rapidly. As new energy vehicles gradually enter the scrap period, the vehicle power lithium-ion battery recovery has become a realistic issue that has had to face new energy vehicles. How to break through the industrial development dilemma, is also a problem that needs to be solved.

Under the strong support of the country, my country's new energy automotive industry has developed rapidly, especially since the beginning of the market in 2014. According to statistics from my country Automotive Industry Association, in 2016, my country's new energy vehicle sales reached 507,000, and the market has reached 1 million. The new energy vehicle is a national "13th Five-Year" emerging strategic industry, which is expected to be further developed.

Dynamic lithium-ion battery usually is generally 5-8 years, which means that from 2018, my country's first new energy vehicle power lithium-ion battery will face the issue of scrap recycling. According to forecasting, by 2020, my country's car power lithium-ion battery accumulated credit will expect to reach 200,000 tons, and with the development and time of development and time of new energy vehicles, the pressure of the dynamic lithium-ion battery will be more The bigger, how to recycle the scrap dynamic lithium-ion battery will be the key to affecting the development of new energy vehicles. Car power lithium-ion battery recycling is important for environmental protection and resource savings: (1) If the scrap battery is not properly disposed, it will cause pollution to the environment.

Although the lithium ion power lithium-ion battery does not contain a heavy metal element such as mercury, cadmium, lead, etc., but also brings environmental pollution. For example, once its electrode material is entered into the environment, hydrolysis, decomposition, oxidation, etc.

in other plays, may cause weight environmental pollution, including the pH of the soil, and may have a poisonous gas properly. (2) Battery recycling is beneficial to resource savings, improve battery use value. Composition of the positive electrode, negative electrode, diaphragm, electrolyte such as lithium ion battery containing a large amount of price metal.

Studies have shown that recycled lithium-ion batteries can save 51.3% of natural resources, including reduced 45.3% of ore consumption and 57.

2% of fossil energy consumption, if you can get reasonable recycling, it will play a purpose of resource conservation. At the same time, from the vehicle scrap battery, although the new energy vehicle usage requirements can be met, it can meet the performance requirements of other applications, such as the reserve power supply of the valence of the scenery, the smart grid, the backup power supply, etc., thus power lithium Ion battery recycling reuse can realize the reuse of the value of the power lithium ion battery, effectively reducing the cost of the electric vehicle.

Although the dynamic lithium-ion battery recovery industry is considered to have important market value, we should also see that my country's powered lithium-ion battery recycling industry is still in the early stages of development, and the industrial closed loop has not yet formed, slow development, 2015, domestic scrap power The recovery rate of lithium-ion battery is only 2%, the reason, the important existence: First, the policy and regulatory system is not perfect. Although the government has already issued some policies and regulations, there is no mandatory legal policy, nor does it really implement the law, clear the rules of penalties; second, industry development is irregular. The industry standard is not perfect, while the battery type is more specifications, the production company is more, the car is more, the recycling company is zeroing, the important is mainly based on the small workshop, which is not conducive to the standardization, scale development of the dynamic lithium battery; third, the market is not yet mature.

Although the dynamic lithium-ion battery recovery problem is unobucided, since my country's motivational lithium-ion battery began to enter the peak period of recovery, the previous market is not mature, and the public awareness is not enough for the importance of dynamic lithium-ion battery; fourth, recycling costs Higher, poor economy and safety. Since the battery does not have a unified standard in size, structural, etc., resulting in a complex battery dismantling, low efficiency, and high recovery process cost.

At the same time, due to the reuse of the scrapped battery must be evaluated by quality detection and status, the pre-battery consistency is poor, lack of complete data records, high equipment and labor costs, and the consistency and reliability of the battery cannot be guaranteed. Therefore, the economic and safety of the dynamic lithium-ion battery recovery makes many companies and capital look. So how to promote the development of the dynamic lithium-ion battery recycling industry, we believe that the dynamic lithium-ion battery recovery is a complex, mutual restriction industry, and its development should give a multi-party synergy, form a benign interaction cycle to promote the rapid development of the industry.

(1) The state should improve the policy and regulatory system, strengthen supervision, and guide the development of industrial regulations. At present, my country has not specifically established a special legislation for the recycling treatment of dynamic lithium-ion battery, lacks recycling company access conditions and management methods, and my country's battery recovery standard system is missing, restricting the effective recycling of vehicle power lithium-ion batteries, should speed up Dynamic lithium-ion battery recycling regulations and standard system construction, improve the normality of dynamic lithium-ion battery recovery, create a good environment for recycling of dynamic lithium-ion batteries. At the same time, the dynamic lithium-ion battery recycling incentives and punishment measures will be implemented, and the representative cities can choose the demonstration pilot work, encourage companies with certain technical strength to carry out recycling industrialization, give certain subsidies and tax benefits, can use consumers The deposit and rewards are parallel, and "ordering the imperial", the necessary punishment for companies that do not fulfill their responsibility obligations in accordance with the recycling policy, including administrative punishment and economic penalties, guide the development of industrial regulations.

(2) The industry needs to integrate industrial advantageous resources, build a platform, and promote the effective recovery of the battery. The development of the dynamic lithium-ion battery recovery industry is inseparable from the collaboration of the industry upstream company, but also more centralized and large-scale industrial forms. It is recommended to take the lead in the industry, integrate the industry's advantage resources, carry out key common technological research, and encourage key companies to do high-quality, formation of scale; build power lithium-ion battery manufacturers, electric vehicle manufacturers and third-party recycling agencies.

Jointly carry out the recycling and re-use of dynamic lithium-ion battery, establish a strong influence, coverage, and form a sustainable circular economy model, and promote the effective recovery of the battery. (3) Recycling companies should increase research and development, optimize process, and improve innovation and development. At present, my country has basically mastered the recycling technology, but the level of recovery process is low, the safety and economy of recycling batteries is low, and the company should increase key technologies such as scrap battery dismantling, reorganization, test and life prediction, while Improve the process level and automation level of dismantling, reorganization, and recovery technology, improve the efficiency of disassembly, reorganization and recovery process, reduce cost, innovate business model, so that the power lithium-ion battery recovery materials and reuse battery factory has economical Feasibility and economy, driving the sustainable development of battery recycling industry.
