With the vigorous promotion of new energy vehicles, the dynamic lithium battery newspapers are also coming, and the huge recycling market in the future will challenge my country's recycling system and technology. In the past two years, the development of new energy vehicles is rapid. From a global, 2015 global new energy vehicle sales is 5.

28,000, 770,000 in 2016, a year-on-year increase rate is 42%, and the global new energy passenger sales have exceeded 1 million units from January to November 2017. It is expected that the annual sales will exceed 11 million units. By 2020, sales will reach 3 million, even higher.

my country has become a new energy vehicle to promote the first big country. In 2016, my country's new energy vehicle sales reached 507,000, from January to November 2017, my country's new energy vehicle sales reached 609,000, up 51.4% year-on-year, and it is expected to be finished in 2017.

The sales of new energy vehicles in China is about 700,000. According to the new energy vehicle development plan, by 2020 new energy automotive production and sales will reach 2 million, and the new energy vehicle guarantee will reach 5 million units. With the rapid development of the new energy car, a problem that cannot be ignored is also caused by concern - some power lithium battery begins to enter the scrap period, and the recycling of the use of waste power lithium batteries is imminent.

Studies have expected that by 2020 movement lithium-ion battery scrap will reach 32.2GWH, about 500,000 tons, and the overall scale of the lithium-ion battery recovery market will reach 15.6 billion yuan to 2020.

By 2023, the amount of scrap will reach 101GWH, about 1.16 million tons. According to relevant agencies, the power lithium battery will be the fastest to usher in the first batch of retired tides in 2018, and the rapid rise in the next three years; the recovery value of lithium-ion batteries according to different materials is expected to recycle the market size of the 2020 It will reach 15.

6 billion, the compound rate of composite increase in 2017-2020 is 40.84%. Dynamic lithium battery recovery mode power lithium battery will experience four phases from the factory to scraps: the performance of the dynamic lithium battery decays with the number of times, when the performance of the power lithium battery decreases to 80% of the original performance It will not be able to reach the standard standard of electric vehicles, but can still be used in applications with low performance requirements of the power lithium battery, that is, enter the ladder utilization stage, such as energy storage systems, distributed photovoltaic power generation, low-speed electric vehicle, etc.

When the performance of the battery is further reduced to not suitable for the ladder, it will enter the stage of recovering reuse reuse. This is the two types of cyclic utilization modes recycling by power lithium batteries: ladder utilization and dismantling recycling. At present, the tradder is still dominated by the entire recycling market, but the type of the battery is different, the size is also a big problem.

Technical accumulation is critical to the tracting of the dynamic lithium battery. On the stage, the dynamic lithium battery is used to use in actual operations. Regarding the company, we should continue to increase technology research and development, improve efficiency, reduce costs, and government should also increase the company's support for technology innovation.

Compared to the ladder utilization, the dismantling recovery is the last loop of the power lithium battery recovery, which can promote the return of the dynamic lithium battery to harmless, resource. But to turn the used battery into a valuable thing, you need to break through the recycling technology. my country's waste dynamic lithium battery ladder is huge, but the current scrap volume is small, the recycling channel and the recycling system are still immature.

The company is still in the technical accumulation and development phase, and the treatment of waste batteries is still in market and technology. Cultivate stage. With the increase in power lithium battery scrap in the future, in the face of subsequent useful power lithium batteries, it is necessary to increase investment in business model, and accelerate the technical problem in recycling, transportation, dismantling, and ladder utilization.

Dynamic lithium battery recycling pattern has two mainstream technology routes, dry metallurgy and wet metallurgy. At present, the wet metallurgy technology route has realized the scale recovery of consumer-free lithium-ion batteries to extract cobalt and nickel, once the power lithium battery recovery end can achieve the recycling of the dynamic lithium ion battery, will break through many technologies Barrier. As the recovery of waste lithium ion battery is increasing, the new energy automotive industry chain company accelerates the layout of the dynamic lithium battery recovery, basically forms the line of lithium-electric materials, power lithium batteries, third-party institutions.

Prototype. From the perspective of industrial health development, the recycling of power lithium batteries has extended the industrial layout, enhances the competitiveness of related companies, and effectively guarantee the supply of raw materials, and gradually constructs the industrial chain of resource recycling. From the perspective of the power lithium battery line, the layout of retired dynamic lithium battery is ladder by self-built or third-party institutions, and the recovery of the raw material of the lithium-ion battery will help alleviate the price increase of upstream materials and downstream vehicle companies.

Equal pressure. From a lithium electrical material, the recovery of the power lithium battery can not only expand the supply channel of the raw material, but also protect the supply of raw materials, but also reduce procurement costs, improve product profitability, and further improve the industrial chain layout, and create a material system closed loop. In addition, in the recycling link, resource recycling company and material production company is more advantageous.

From the recycling channel, the source of waste battery is important is an automobile maintenance company, battery production company, and scrapped car dismantling company. The battery company and the vehicle factory generally only build recycling channels for their own models, and professional third-party recycling company is recycling Channel layout is more comprehensive. From the perspective of technical support, the material company uses itself to understand the material synthesis process, deep digging material recovery treatment technology, can reduce the material cost of material in the case of high metal prices.

Potential environmental risks are still in fact, and many new energy vehicles in China have not had actual actions in power lithium battery recycling. More is to be tangled with battery manufacturers in recycling main body responsibility, leading to dynamic lithium battery recovery. Stop in research level.

If the new energy vehicle power lithium battery does not achieve effective dismantling recovery, there will be hazardous solid waste, resulting in organic substances and heavy metal pollution. Despite the strong environmental protection characteristics, new energy vehicles, the recovery of dynamic lithium batteries is more targeted, and the scientific and effectiveness of lithium-ion battery recycling and utilization regulatory system should be established as soon as possible. First, the traditional car scrap and recycling market chaos have not yet been effective, the number of revisitors and lead-acid batteries have been informal acquisition, informal dismantling, and the recovery process did not have effectively supervised, the recycling place is remote; second, the lack of qualifications And small workshop illegally recover lead-acid batteries, directly discharge waste acid solution, has caused severe pollution of some regional environments.

The healthy development of any industry is inseparable from the standard and standard system. If the ladder of the power lithium battery is not specified and guided, the industry will be chaotic, which in turn affects the power lithium battery industry and the new Energy automotive industry. Therefore, in recent years, my country's related departments have not yet introduced a series of dynamic lithium battery recycling policies.

Waste dynamic lithium battery recycling standards to be unified since 2012, the State Council "Energy Saving and New Energy Automotive Industry Development Plan (2012-2020)" stipulates: Strengthening power lithium battery step utilization and recycling management. Develop power-lithium battery recycling management methods, establish dynamic lithium battery steps and recycling management systems, clarify the responsibilities, rights and obligations of all relevant parties. In July 2014, the "General Office of the State Council's guidance on accelerating the promotion of new energy vehicles" proposes: To study the development of dynamic lithium battery recycling policies, explore the use of funds, deposits, mandatory recycling and other means to promote waste dynamic lithium battery recycling, establish Improvement of waste dynamic lithium battery circulation utilization system.

Since 2016, the Ministry of Industry and Information Technology has issued "Electric Automotive Power Battery Recycling Technology Policy (2015 Edition)" "New Energy Automobile Waste Battery Comprehensive Utilization Industry Standard Conditions" 3 files, clear the subject of recycling of waste batteries, strengthen industry management and recycling supervision. In May 2017, the State Administration of Quality Supervision, Inspection and Quarantine, the National Standardization Management Committee approved the "Specification for the Recycling and Utilization of Car Power Lithium Battery" (referred to as "Decomposition Specification"). This is the national standard for the recycling of car power storage batteries as the leading car technology research center in my country.

On May 12, 2017, the National Standardization Management Committee officially approved the "dismantling norm" and decided December 1, 2017. In the view of the inside of the power lithium battery company, "Decomposition Specification" has improved the safety, operation procedures, storage and management of waste dynamic lithium battery recycling, but The largest constraint for the recycling of waste batteries, that is, the size of the battery model is still not involved. Industry insiders said that the unified relevant standards are the direction of future policy efforts, try to establish a unified standard facilitating the operation of recycling chains.

However, it is still necessary to encourage differentiation, because technical indicators such as energy density are the embodiment of competitiveness in the market competition in battery companies, and the internal architecture of unified standards must also be discussed. The relevant institutions are expected to be based on corresponding scrap standards, in 2018, my country's powered lithium battery waste recycling market will begin the scale, and the recycling company is about to usher in the profit point brought by scale. SMM Cobalt Analytics Hong Yu believes that my country's powered lithium battery recycling market is difficult to achieve breakthrough development in a short time, but in 2017, the industry's upstream integration process accelerated, from multi-signed strategic cooperation agreement, the action of the future recycling industry Size, but the operation mode can be promoted smoothly, still need to guarantee the sound protection of industry standards and laws and regulations.
