Recycling capacity will exceed 248,000 tons in 2020 Power battery recycling is imminent

- Dec 16, 2017-

According to the Ministry of Industry and Information, in the first three quarters of this year, China's NEV production and sales reached 424,000 units and 398,000 units respectively. According to the plan, the cumulative production and sales of new energy vehicles in China will reach 5 million by 2020. As the scale of new energy vehicles continues to expand, China has become the world's largest power battery producer. As the power battery average retirement period of 5-8 years, it is predicted that by 2020 the battery scrap will exceed 248,000 tons, about 20 times the amount of scrap in 2016. Power battery recycling is imminent.

Scrap batteries if not properly handled, not only will result in waste of resources, the environment will also cause huge pollution. At present, the main power battery in China mainly lithium iron phosphate, there are some ternary lithium batteries, and a small amount of lithium titanate, lithium cobalt oxide, lithium manganese oxide batteries. The common feature of such batteries is that they have a significant negative impact on the environment, whether they be cathode materials, anode materials, or electrolytes, including new high-energy lithium-ion batteries such as high-energy battery cells that may emerge in the next few years No exception.


When NPC Standing Committee examined and examined the "Solid Waste Law" law enforcement inspection report in a separate group, Luo Baiming, vice chairman of the Overseas Chinese Affairs Committee of the NPC, once proposed: "What should we do if the booming and deteriorating electric vehicles and batteries scrapped? To arrive, imminent. "How to safely recover, environmental protection and strengthen the recycling of used batteries standardized, has become a topic of universal concern to the industry.


In this context, the new energy battery recycling management system and related rules are urgently introduced. Ministry of Industry has made its position, for the new energy vehicles battery recycling, will establish a producer responsibility extension system. Car manufacturers in the sale of new energy models need to be responsible for battery recycling.


Power battery recycling there are two main recycling processes, respectively, for the use of recycling and dismantling recycling. Power battery performance will decline with the increase in the number of charging, when the battery capacity decay to less than 80% of rated capacity, the power battery is not suitable for electric vehicles. At this moment, the decommissioned power battery is utilized in the fields of energy storage, distributed photovoltaic power generation, low-speed electric vehicles and the like, and is called as echelon utilization. When the battery can not be used for echelon utilization, it needs to be disassembled and recovered.


Undoubtedly, the accumulation of technology is crucial for the battery utilization. For enterprises, R & D investment should be continuously increased to improve efficiency and reduce costs, while the government should increase its support for technological innovation. From this perspective, companies with the technical expertise and advantages will dominate the power battery recycling market. For the dismantling and recycling of power battery, the entire industrial chain should be expanded to promote synergies between upstream and downstream to build a sound recovery system. At the same time, due to the fact that most of our cobalt, nickel and lithium resources rely on imports, the imbalance between supply and demand of battery metal materials highlights the fact that enterprises should also increase the recovery rate of cobalt, nickel, manganese and lithium metal resources.


There is huge market for recycling and dismantling waste batteries in China, but the current scrap volume is small, the recycling channels and recycling system are not yet mature, and the enterprises are still in the stage of technology accumulation and R & D. The disposal of used batteries is still in the market and technical cultivation stage. With the increase of battery scrap in the future, in the face of the continuous growth period of used batteries, we need to increase investment in exploring business models and speeding up technological challenges in terms of recovery, transportation, disassembly and utilization of echelon.


The healthy development of any industry is inseparable from the norms and standards system, if the power battery echelon utilization and recycling technology thresholds and processes, such as not to regulate and guide the industry will chaos, and thus affecting the battery industry and new energy vehicles industry.


The good news is that China's first national standard for battery recycling, "vehicle power battery recycling specifications" from December 1 this year, the official implementation. Clearly pointed out that recycling dismantling enterprises should have the relevant qualifications to further ensure the safety of battery power, environmental protection and efficient recycling. In addition, on February 1 next year, "car battery recovery and utilization of energy to detect" three new national standard battery will also be officially implemented.


Reason to believe that with the release of national standards, the current chaotic power battery recycling and utilization of the ladder is expected to change. This standard sets strict requirements on the safety, operation procedure, storage and management of the recycling of used power batteries, and regulates the recycling, dismantling, professional technology and recovery system of automotive power batteries in China, To solve the problem of industry development.


Obviously, relative to the raw materials of mine production, metal recycling is much better, and it has great advantages in energy conservation and emission reduction. The recovery of power battery is related to the issue of building a low-carbon economy and environment-friendly. The state vigorously promotes the recovery and utilization of power battery It is imperative.
