With the rapid development of my country's new energy auto industry, the power lithium-ion battery will usher in a large-scale retirement tide. According to the industry, in 2018, my country's retired dynamic lithium-ion battery will be nearly 12GWH. The recovery of lithium-ion battery in 2020 will be close to 25GWH, while 2022 lithium-ion battery recovery will be close to 45GWH.

Pioneering research believes that as the power lithium-ion battery is retired, the last kilometer of the new energy vehicle will become the next blue sea. The actual significance of battery recovery and ladder uses the "dismantling recovery" and "ladder utilization" in the industry. At present, my country is already the world's largest power lithium-ion battery market, so large-scale power lithium-ion batteries aggregate, doing battery recycling and ladder utilization work, no matter whether it is economical, resource security, or environmental protection, there is a big Necessity and practical meaning.

"Make bricks without straw. "The processing of the power lithium-ion battery is inseparable from raw materials. With the rapid development of my country's dynamic lithium-ion battery industry, the demand for battery raw materials is also more powerful.

Cobalt and nickel are the most scarce resources in the power lithium-ion battery. Since 2016, the price of nickel has doubled from the low point, and the price of cobalt has doubled more than three times. Half of cobalt reserves in the political bureau's extremely unstable Congo (Gold).

Hand caught child labor incidents, and rumored profitears on rumors seriously affected the price of cobalt stability and company mining. In the case where the rare resource price is soaring and uncertain, the resources are acquired from the battery recovery, extend the battery life cycle, becomes extracted. Battery recycling has a huge economic value.

In the case where the prices of upstream materials are continuously increased, the revenue of the three-yuan battery is very high. At present, the cost of the three-yuan battery recovery is about 15,000-20000 yuan / ton. After recycling, the metal materials can be sold to 42,000 yuan according to the current resource prices.

Pioneering research stated that in 2022 domestic power lithium-ion battery recycling market, the scale of domestic power lithium-ion battery will break through 10 billion yuan, and will continue to be great as the new energy industry increases. From an environmentally friendly perspective, the waste-powered lithium-ion battery contains a large number of heavy metals and organic substances, electrolytes and their transformants, which will seriously threaten the environment and human health, causing huge pressure to social ecological environment. Therefore, do a good job in the recycling of power lithium-ion battery and the use of ladder, and it is also a major ecological construction task.

The principle of secondary lattice is used to use the principle of recycling. The power lithium-ion battery is uniformly used in 5-8 years, and its performance has attenuated by the number of charging times, and the residual capacity of the battery is reduced to 70% -80% of the initial capacity. When you can't meet the requirements of car power.

However, the retired dynamic lithium-ion battery can be used for low-speed electric vehicles, backup power supplies, and power storage capacity, etc., which is relatively good. When the battery is unable to make a ladder, the disassembly recovery is to be resolved.

The development of Xintai believes that from the perspective of resource utilization, the pen will be recovered as a raw material from the perspective of resource utilization. The electric vehicle stage only accounts for 36% of the battery full life cycle, if the ladder is not taken, its cost is calculated according to all costs of the battery lifecycle. When the ladder uses the power lithium-ion battery cost at 1000 yuan, the service life exceeds 1000, and the price is exceeded by the lead-acid battery.

In the Interim Method of Recycling Management of New Energy Automobile Power Battery Battery in the National Multi-Party Committee, the utilization of waste power storage batteries should follow the principle of regenerative use of the first tramid. The obstacle and pattern of the ladder use is currently, my country's ladder has been able to use the energy storage system to do 1 yuan / WH, but because there are still many obstacles, there is still not large-scale promotion in China. Pioneering research pointed out that my country's powered lithium-ion battery has not officially entered a large number of retired stages, so the number of batteries that can be used in the ladder is not enough.

And early dynamic lithium-ion battery performance, quality and cost is not as good as the battery. Tuojin research emphasized that due to the rapid advancement of my country's dynamic lithium-ion battery industry in the past few years, it has led to the lack of data, and the performance and specifications of the decommissioning battery are uneven, and the test matching is difficult to use, so that the current ladder uses marketization Very difficult. From the national level, the relevant industry supporting policies have not yet landed, for example, my country's minute pricing is not fully implemented, so that the economic efficiency of the energy storage battery cannot be maximized.

Therefore, there are currently a dynamic lithium-ion battery to use projects to explore the verification phase. The development of Xintai believes that as compared with the ternary battery, the lithium iron phosphate ion battery is more suitable for the ladder. Due to resource price factors, lithium iron phosphate ion battery recovery is very low.

However, its own capacity retention rate and electrolyte baking rate are higher than that of the ternary battery, the number of accumulation is higher, safer, and the value is also higher. At present, the lithium iron phosphate ion battery has limited space in performance and cost, so the lithium iron ion battery will be more suitable for the ladder of the three-yuan battery in the energy storage industry. With the improvement of battery performance, the cost of the existing and future dynamic lithium-ion batteries is greatly improved.

Domestic companies have also begun to lay out in battery recycling and ladder utilization. At the beginning of 2018, my country Tower and Chongqing Chang'an, BYD, Yinlong and other 16 new energy companies, signing the "New Energy Automobile Power Battery Recycling Strategic Partner Agreement", explored the model of dynamic lithium-ion battery ladder. The applicable scene and business model development of the ladder is believed that the ladder use not only further reduces battery costs from the business model, but also reduces battery costs, but also promotes more energy storage and marketing and market.

Different energy storage scenarios are different for battery requirements, so the retired dynamic lithium-ion battery ladder uses the applicable scene and business model is the next problem to explode. Innovative attempts of foreign shaving use have greatly learned significance for the domestic market that has just started. Freewire, USA launched a motor vehicle mobile charging station called MOBI.

This product is made of waste electric vehicle battery, which can store 48kWh power, exceeding the battery capacity of most electric vehicles on the market. Nissan Motors and Sumitomo Commercial Co., Ltd.

established 4Renergy Co., Ltd. at 2010, dedicated to achieving secondary commercial use of lithium-ion batteries in Nissan Health, and the company recycling Japan and the US market for use in the use of waste batteries for residential and commercial use Energy storage device.

In Europe, younicos recycling batteries to establish a virtual power plant that combines distributed energy, and will participate in the electricity price of a FM market. The German Bosch Group built 2MW / 2MWH large photovoltaic power storage system with BMW's Activee and i3 pure electric car scrapped battery. In addition, Tesla is also deployed in power grid-level energy storage, household energy storage wall, solar energy storage.

These will be the scene of the potential ladder. Industry Alliance leading battery recycling models related to the scrapped battery that cannot be used, it is necessary to disassemble the recycling through technical means. From the related experience from abroad, Japan has gradually established "battery processing-sales-recycling-regeneration solution", from 1994.

The car dealer is responsible for recovering waste car batteries free of charge to the society, while car battery processors recover for waste batteries. After collecting waste batteries from the dealer, the processor is transferred to the recycling battery. Although the United States currently does not have a regulatory policy in the federal government, Tesla is in North America and Europe, with the battery recycling company Kinsburskybrothers and Umicore to recycle the battery.

According to the current domestic policy direction, my country's recycling mode is between Japan and Tesla model, which is dominated by processing companies. In February 2018, the seven ministries of the Ministry of Industry and Information Technology announced the "Interimming Method of New Energy Automobile Power Battery Recycling Management", put forward the implementation of the processed responsibility extension system, putting the car processing company's first responsibility, and also encourages automobile and battery processing Company, scrapped car recycling dismantling company and comprehensive utilization company and other cooperation to build a recycling channel. At present, the form of alliance is gradually formed:.

These alliances will lay industry models in my country's powered lithium-ion battery recycling. The research of Xijinjin believes that the dismantling of the dynamic lithium-ion battery in my country has just started. As the power lithium-ion battery is getting closer, the task falling in my country's battery industry has become increasingly More urgent.

Stones from other hills, can learn. Domestic companies should be based on my country's market environment, actively learn from foreign success related experience, find ways to handling their own industries. I believe that under the joint efforts of my country's government's policy support and the common majority of battery industry chain companies, they will form a relatively complete battery recovery and ladder utilization model.
