Analysis of Lithium Battery Pack Recycling Market

Lithium battery packs can be regarded as the peak period for recycling and reuse this year, but the recycling and reuse of lithium batteries has not been a perfect solution, resulting in a lot of batteries wasting a lot of renewable resources. How to recycle safely, deal with environmental protection, and strengthen the standardized recycling of used power batteries has become a world-class problem. The reuse and recycling of lithium battery packs will bring huge economic income to the new energy market. my country's power batteries will usher in a 'scrap tideLithium electric vehicles used in China's new energy vehicles, due to the technical level and frequency of use restrictions, are designed to have an effective service life of about 3 years, and they need to be replaced after 3 years. 2018 is the first year for the recycling of lithium battery packs for new energy vehicles, and my country's new energy vehicle power batteries will enter a stage of large-scale retirement. The five major bottlenecks encountered by lithium battery packs need to be broken through: 1. Uncertainty in the recycling mode of lithium battery packs Despite the difficult start, the industry is generally optimistic about the prospects. On the whole, the current large-scale 'decommissioning tide' of power batteries has not yet arrived, and it is difficult for the dismantling and recycling of power batteries to form a large-scale effect. For example, some car companies choose to cooperate with other companies to jointly promote domestic power battery recycling and other related matters. 16 vehicle and battery companies, including Changan, BYD, and Yinlong New Energy, have reached cooperation with China Tower Corporation, a major power battery recycling company, to solve problems such as the recycling and reuse of decommissioned power batteries. However, the overall recycling model has not yet been determined. 2. Absence of the main body of lithium battery pack recycling. According to the characteristics of power batteries and the principle of recycling, my country currently advocates the principle of cascading use of decommissioned power batteries and then scrapping and recycling, and requires vehicle companies to be the main body of power battery recycling and undertake power battery recycling. responsibility. However, since most vehicle companies are only electric vehicle 'assembly plants; The second category is battery production companies; the third category is power battery scrap recycling and processing companies and raw material companies. According to regulations, auto companies should bear the main responsibility for recycling, but auto companies are not omnipotent. To a certain extent, car companies are more like 'assembly factories' of electric vehicles. They are responsible for the normal use of lithium battery packs, production and supply, secondary utilization, and recycling during the warranty period, but they are the expertise of battery companies. Unfortunately, battery companies are often excluded from the recycling system, and their responsibilities are currently unclear. 3. The bottleneck of lithium battery pack recycling technology needs to be broken. Due to the complex composition, the recycling and reuse of power batteries faces many restrictions and high technical thresholds. There are considerable differences in the types, specifications, and processes of retired batteries, and there are diversity in series and parallel group forms, application models, use time and working conditions, resulting in complex disassembly. At the same time, my country has not issued a unified standard for power batteries, and it is still difficult to use them on a large scale. From the perspective of recycled batteries alone, even if it is a lithium battery pack, there are a wide variety of cathode materials. The mainstream ones include lithium cobalt oxide, lithium manganate, lithium nickel cobalt manganese, and lithium iron phosphate. Leach with acid-base solution, and then go through a variety of chemical procedures to extract metal oxides. However, the extraction conditions of the components of these oxides are different, and the mixed solution is more difficult. 4. Policies and regulations are not sufficiently supportive and binding. According to industry insiders, my country has formulated the 'Hazardous Waste Pollution Prevention and Control Technology Policy' and the 'Waste Battery Pollution Prevention and Control Technology Policy'. Technical PolicyThese policies and technical standards are all guiding or recommended guidance documents, which have a reference and guidance function for key enterprises with standardized business operations, but have no binding effect on illegal traders. 5. Recycling technology processing lags behind. The entire process of recycling waste power lithium battery packs includes dozens of complex steps such as discharging, dismantling, crushing, sorting, impurity removal, and element synthesis, involving physics, chemistry, materials, engineering, etc Interdisciplinary, complicated and lengthy in technology. At present, many developed countries, including Germany, the United States, and Japan, are actively supporting and promoting the engineering research and development of common key technologies in this field. However, my country lags behind its international counterparts in terms of power battery recycling and processing technology. In view of the above problems, the entire battery market should further explore how to safely and efficiently realize the cascade utilization of lithium battery packs, establish a benign recycling system that can be monitored throughout the process, explore the cascade utilization technology of power batteries, and realize the reuse of lithium battery packs as soon as possible to avoid Bring unnecessary environmental pollution.
