the impact of battery production on the environment -Lithium - Ion Battery Equipment
The problem of lithium -ion battery pollution, the impact of lithium -lyric battery production on the environment. New energy vehicles have the advantage of green and environmental protection because of the use of electricity as energy. However, the majority of netizens do not take it for granted that although new energy vehicles have a lot of oil and zero emissions, the lithium ion batteries they use are very Large pollution. This is really right, but what are the pollution of lithium ion batteries? How much does the production of lithium -ion batteries on the environment? Let's talk about this topic today.
Lithium -ion battery pollution problem
According to data, in 2017, my country's automobiles sold 28.8789 million vehicles, ranking first in the world, an increase of 3%year -on -year. The national automobile ownership has approached 200 million. Last year, the total global car sales were about 90 million vehicles, and one of the three cars sold in the world was bought by Chinese people. From the perspective of the proportion of the ownership, it was also around 15%.
Lithium -ion batteries, such as lead acid, nickel chromium, nickel -metal metal metal elements and substances without any lead, mercury, cadmium and other toxic and harmful metal elements and substances, relatively small pollution. And its electrolyte is organic solvents and lithium salts, mostly non -toxic or low toxicity; however, lithium -ion battery decomposition or hydrolyzed products are hydrofluoric acid and other fluoride -containing compounds, which have certain corrosion and toxicity. If the recycling disposal is improper, it is also likely to repeat the wrongd acid battery that year, causing serious pollution to the environment.(Lithium - Ion Battery Equipment)
According to the multi -party information obtained by Xiaobian, although lithium -power lithium batteries do not contain heavy metals such as lead and cadmium, in terms of technical technology, in addition to "lithium", nickel, cobalt, manganese, manganese still have the electrolytes. For heavy metals, electrolytes, fluorine -containing organic matter is also polluted. In addition, after scrap, it still has high pressure ranging from 300-1000V. In improper operation during recovery, disassembly, and processing, there may still be a variety of problems such as fire explosion, heavy metal pollution, and organic exhaust emissions.
The impact of lithium -ion battery production on the environment
In the process of making lithium -ion battery pole slices into these links, there is no large pollution in the domestic mainstream domestic iron phosphate system, or even the ternary system. Of course For example, cobalt, manganese, and nickel are considered heavy metals, but they are relatively environmentally friendly. Among them, lithium iron phosphate is the most environmentally friendly.
The remaining part, in addition to the pollution of the materials above, the solvents in the injection are important to be ring/chain -shaped carbonate or carboxylic acid. It is important for solubility. Lithium salt hexafluorophosphate. The important additive is film additive, flame retardant additives, conductive additives, and improve low temperature discharge additives. The pollution throughout the process is also okay. Of course, chemical agents, do not pay attention to their control, must be polluted for the environment. As for the final packaging and turning, the pollution is even smaller.
It is reported to say that batteries contain mercury, cadmium, lead, arsenic and other substances, which is inaccurate. In fact, there is no need to add cadmium, lead, arsenic and other substances during the production process of ordinary dry batteries that the masses. The mercury in the waste battery does not have a low volatile temperature of the environment that threatens mercury, and is a heavy metal with a large toxicity. The soil in many places also contains micro -mercury. During the processing of mercury mine mining, refinement, and mercury -containing products, if the closed measures are not complete, the mercury released to the air has a great impact on the health of the operator.
Although the battery contains mercury, its content is small because it is an additive. Even with high mercury batteries, the mercury content is generally one thousandth of the battery weight. The amount of mercury in my country's battery industry is generally comparable to the mercury content in the annual discharge of wastewater with a mercury method, or mercury alchemy, or the selection of high mercury lead -zinc ore. Due to the large battery consumption area, after the mercury waste battery enters the domestic waste treatment system, the impact on the environment is much smaller than the effects of mercury wastewater discharged by a chemical company.
