3500mah 18650 battery recycling market size, scrapped 3500mah 18650 battery recycling process methods

　　3500mah 18650 battery recycling market size, scrapped 3500mah 18650 battery recycling process methods. China has become the world's largest producer of lithium power batteries. However, under the appearance of this "prosperous age", there are hidden concerns such as backward resource development and utilization capabilities, low power battery technology, and a blank 3500mah 18650 battery recycling system, which limits industrial competitiveness. China must get rid of existing bottlenecks, accelerate the construction of standardization systems, improve the recycling and reuse system, and master breakthrough core technologies in order to gain an advantage in this competition. This article will introduce the size of the 3500mah 18650 battery recycling market and the recycling process of scrapped lithium batteries.

　　3500mah 18650 battery recycling market size

　　Lithium batteries need to be recycled after the end of their life cycle, mainly for environmental protection and economic considerations. Lithium batteries usually contain many harmful substances. Ni, Co, and phosphide have an ecotoxicity score of over 1,000 and are considered high-risk substances. If used lithium-ion batteries are treated by ordinary garbage disposal methods (including landfill, incineration, composting, etc.), the metals such as cobalt, nickel, lithium, manganese, and inorganic and organic compounds will definitely cause serious pollution to the atmosphere, water, and soil. , extremely harmful.

　　As of the end of 2017, my country has promoted more than 1.8 million new energy vehicles, with about 86.9GWh of power batteries installed. After 2018, new energy vehicle power batteries will enter large-scale retirement, and it is expected that the cumulative number will exceed 400,000 tons by 2022, with a compound growth rate 70%. It is expected that the 3500mah 18650 battery recycling market will show rapid growth in the next three years, and the market size is expected to exceed 15.6 billion yuan by 2020, with a compound annual growth rate of 41%.

　　Overall, the government is the biggest supporter of the new energy vehicle recycling industry. Since 2015, it has intensively introduced a variety of policies to support the healthy development of the industry, and local governments have also introduced subsidies and tax incentives accordingly.

　　According to statistics from the China Chemical and Physical Power Sources Association, lithium-ion batteries achieved a high growth rate of 42% in the battery category in 2016. The development of the Internet of Things and smart chips also caused lithium batteries to have a growth rate of more than 10%. Most of the other categories (nickel Cadmium batteries, nickel-metal hydride batteries, zinc-manganese batteries) are showing a shrinking trend. Therefore, lithium batteries have entered a period of accelerated growth, and the recycling market will also show rapid growth in the future.

　　As a device that converts chemical energy and electrical energy into each other, lithium batteries have relatively reversible chemical reactions taking place inside. The side reaction between the negative electrode and the electrolyte is the main limiting factor in its cycle life. Usually consumer batteries have a life cycle of 3-6 years. Depending on the function of the electrical appliance and the frequency of replacement, the general scrap cycle is about 5 years. Power lithium batteries are used in new energy vehicles, and their lifespan is mainly determined by the charging frequency. Operating vehicles such as online ride-hailing, taxis, and buses usually charge 7 times/week, while private cars usually charge once/week. Overall, the life cycle of power batteries is also about 5 years. Based on this estimate, it is expected that by 2025, the amount of scrapped lithium batteries will reach 150Gwh. The potential market for 3500mah 18650 battery recycling is at least tens of billions, and the future development prospects are bright.

　　Scrap 3500mah 18650 battery recycling process method

　　1. Cut the dismantled waste 3500mah 18650 battery negative electrode material into sheets, and then put it into a hammer crusher to peel off the carbon powder and acetylene black powder adhered to the surface of the negative electrode copper foil by hammer vibration;

　　2. A sieve plate is installed under the rotor of the hammer crusher. After hammering, the negative electrode particles smaller than the aperture of the sieve plate fall into the screening equipment below through the small holes of the sieve plate;

　　3. The negative electrode material with a size larger than the sieve plate aperture is crushed by circular hammer vibration in the hammer crusher until the size is smaller than the sieve plate aperture;

　　3. The broken particles falling into the screening equipment use the size and shape differences between the particles to pass through the vibrating screen to separate the metallic copper from the non-metallic carbon powder and acetylene black powder after hammer vibration peeling.

　　How to recycle used lithium batteries

　　The first is to study battery standardization and implement a traceability system.

　　Strengthen research on the standardization of power lithium batteries’ structural design, connection methods, process technology, integrated installation, etc., formulate mandatory standards for power battery coding as soon as possible, link the traceability system with new energy vehicle product announcement management, and ensure that battery life cycle information is recorded , improve the convenience and accuracy of detection and evaluation.

　　The second is to increase the research and development of key technologies for battery recycling and reuse.

　　Increase research on key technologies such as the dismantling, reassembly, testing and life prediction of used lithium batteries to improve their technological maturity and the safety of the production process. At the same time, the automation level and recycling efficiency of battery disassembly, reassembly and recycling technology should be improved to make the recycling and reuse of power lithium batteries economically feasible and safe.

　　The third is to formulate and implement incentives and penalties for power battery recycling.

　　Formulate implementation details for incentives for power 3500mah 18650 battery recycling and reuse, and establish a reward and punishment mechanism. For example, companies that fail to fulfill their responsibilities and obligations in accordance with recycling policies will be punished, battery recycling companies and battery reuse companies will be subsidized based on the number of battery sets, capacity, etc., and tax incentives will be implemented to ensure the economics of recycling and reuse companies; for consumers A system of both deposits and rewards can be adopted to cultivate consumers’ awareness of power battery recycling.

　　The amount of 3500mah 18650 battery scrap is also increasing every year, which will definitely put huge pressure on the environment and resources. As for the end-of-life treatment of lithium batteries, because they contain electrolyte and are difficult to dispose of, their recycling and processing has become a problem. Adequate recycling requires not only changing consumer attitudes, but also requires collaboration between battery manufacturers, consumers and recycling agencies.
