Discarded power lithium batteries cannot follow the old road of batteries

Abandoned power lithium batteries cannot follow the old path of lead batteries. The scrapping of lithium-ion batteries for new energy vehicles has entered a peak period, but my country has not yet formed a complete recycling system. The technology and equipment are not mature enough. On March 4th, Zhang Tianren, a representative of the National People's Congress and chairman of Tianneng Group, said in an interview with my country Automobile News that we should lead by example, strengthen support, and establish a system instead of following the old lead battery path. During the two sessions this year, Zhang Tianren submitted a proposal on strengthening the recycling of used lithium batteries to ensure the strategic security of national resources, and called on the country to attach importance to the recycling of new energy power lithium-ion batteries. Zhang Tianren Zhang Tianren said that good use is a resource, and evil use is rubbish. This is the case with lithium batteries for new energy vehicles, he said. In recent years, the development of new energy vehicles in my country has entered the fast lane. In 2018, the annual sales volume exceeded 1 million for the first time, reaching 1.27 million and 1.26 million respectively, up 59.9% and 61.7% year-on-year, ranking first in the world. It is estimated that by 2020, sales will exceed 2 million vehicles. The service life of power lithium-ion batteries is generally 5 to 8 years, and the effective life is 4 to 6 years, which means that the first batch of new energy vehicle power lithium-ion batteries put on the market is basically at the critical point of scrapping. According to estimates by the my country Automotive Technology Research Center, combined with factors such as the life of scrapped vehicles and battery life, the total amount of scrapped power lithium-ion batteries in my country will reach 120,000 to 200,000 tons in 2018-2020, and 350,000 tons in 2025. On the one hand, a large number of new energy power lithium batteries will be scrapped. On the other hand, lithium resources are heavily dependent on imports. Zhang Yu said that my country imports a large amount of lithium every year. my country's demand has also driven the price of battery-grade lithium carbonate to soar from less than 50,000 yuan/ton at the beginning of 2015 to 180,000 yuan/ton. At the end of 2017, the increase was nearly three times, which greatly increased the purchase cost of lithium battery manufacturers in my country. And our country’s resource security poses a serious challenge. Discarded power lithium batteries are valuable'urban mines', and their metal content is much higher than that of ore. Recycling valuable metals such as lithium, cobalt, and nickel can improve resource utilization efficiency, reduce imports, reduce foreign dependence, and ensure the security of the national resource strategy. Discarded lithium batteries, in addition, if they are improperly handled and discarded, they can also cause great harm to the ecological environment. For example, heavy metal elements in anode materials, such as cobalt, nickel, electrolyte organic substances, anode carbon materials, etc., will cause serious Polluted water and soil, especially once heavy metals infiltrate the soil, it is difficult to recover for decades. Zhang Tianren suggested that relevant departments speed up the formulation of management standards, technical standards and evaluation standards for the recycling of used batteries, such as on-site process specifications for dismantling and packaging systems, and battery residual testing standards. We will encourage local governments and industrial advantages to formulate supervision plans and implementation plans for the recovery and recycling of new energy lithium batteries, and explore, through trials and experiments, to achieve plans that are more in line with the actual situation of the industry at the national level and are more operable. of. He also suggested speeding up the research and development of incentive policies such as fiscal and tax incentives, industrial funds, and point management, researching and exploring market-oriented models such as power lithium-ion battery residual value trading, and promoting the recycling of power lithium-ion batteries; coordinating existing special funds to regenerate smelting System construction and scientific and technological research and supply funding subsidies; determine a number of benchmark companies and demonstration projects, give priority to applying for green manufacturing, energy conservation and environmental protection special funds, and play industry-leading uses; explore the establishment of government subsidies, company and social funds for multiple investment, economic benefits and environment Benefit-sharing-oriented financial support mechanism.
