If the amount of battery scrap generated by the development of the new energy automobile industry is not properly disposed of, it will cause greater pollution to the environment; in addition, discarded lithium-ion batteries have significant resources, and we will analyze lithium-ion batteries below. The technical feasibility and cost-effectiveness of recycling.

　　If the amount of battery scrap generated by the development of the new energy automobile industry is not properly disposed of, it will cause greater pollution to the environment; in addition, discarded lithium-ion batteries have significant resources, and we will analyze lithium-ion batteries below. The technical feasibility and cost-effectiveness of recycling.

　　Waste power lithium batteries have significant resource properties. Among them, cobalt and lithium have the highest potential value. The positive electrode, negative electrode, separator, electrolyte and other materials of lithium-ion batteries contain a large amount of valuable metals. The valuable metal components contained in different power lithium battery cathode materials are different, and the metals with the highest potential value include cobalt, lithium, nickel and so on. For example, the average content of lithium in a ternary battery is 1.9%, nickel 12.1%, and cobalt 2.3%; in addition, the proportions of copper and aluminum have reached 13.3% and 12.7%. If they can be reasonably recycled, they will become A major source of revenue generation and cost reduction.

　　Cobalt is a silver-gray shiny metal, ductile and ferromagnetic. Because of its good high temperature resistance, corrosion resistance, and magnetic properties, cobalt is widely used in aerospace, machinery manufacturing, electrical and electronics, chemistry, ceramics and other industrial fields. It is used to manufacture high-temperature alloys, cemented carbides, ceramic pigments, catalysts, and batteries. One of the important raw materials.

　　The energy-saving rate of metal recycling is between 70% and 90%. If batteries are used to produce batteries with recycled raw materials, it has an absolute advantage in energy saving and emission reduction. Considering the economic issues of lithium-ion battery recycling, it is necessary to consider the full life cycle of the battery. The battery raw materials are mainly non-ferrous metals. There is a clear gap between the energy consumption level of my country's non-ferrous metal industry and the international advanced level. Energy consumption is mainly concentrated in the three major areas of mining, smelting and processing. However, the energy consumption of the non-ferrous metal recycling process is much less than that of primary metals.

　　Abandoned power batteries threaten the environment and human health, and affect the sustainable development of society. The potential threats to the environment and human health are the waste power batteries. The existing disposal methods of waste batteries mainly include solidification, deep burying, storage in waste mines, and resource recycling. However, my country’s current battery recycling capacity is limited. Most of the waste batteries have not been effectively disposed of, which will cause damage to the natural environment and humans. Health brings potential threats. Although the power battery does not contain mercury, cadmium, lead and other toxic heavy metal elements, it can also cause environmental pollution. For example, once the electrode material enters the environment, the metal ions in the positive electrode of the battery, the carbon dust in the negative electrode, the strong alkali and heavy metal ions in the electrolyte may cause heavy environmental pollution, including increasing the pH of the soil, which may be caused by improper handling. Toxic gas. In addition, the metal and electrolyte contained in power batteries are harmful to human health. For example, cobalt may cause intestinal disorders, deafness, and myocardial ischemia.

　　The power battery recycling problem has affected the sustainable development of the society and economy. Electric vehicles have the advantage of coping with environmental pollution and energy shortages. If the power batteries cannot be effectively recycled after they are scrapped, it will cause environmental pollution and waste of resources, which goes against the original intention of developing electric vehicles. For enterprises, the recycling of power batteries contains huge business opportunities. After recycling, it can save battery manufacturers' raw material costs. In addition, the recycling of power batteries is also related to the government's construction of a low-carbon economy and an environmentally friendly society.
