Batteries are now widely used in the market, especially lithium batteries, which account for half of the market. Although lithium batteries have the characteristics of environmental protection and pollution-free, they are not entirely the same. Poor treatment of waste batteries can still cause harm.
Waste batteries contain toxic heavy metals such as mercury, cadmium, and lead. If Mercury is poisoning, it will damage the central nervous system, and the mortality rate is as high as 40%. Waste batteries are also Carcinogens. If people eat food containing lead, it will affect the synthesis of enzymes and normal heme and affect the nervous system. Within a month of landfill treatment, the metal shell of waste batteries will be corroded and perforated, and harmful substances in the batteries will enter the soil and water, causing pollution to the environment.
According to environmental experts testing, if a mercury-containing battery is mixed with 6 tons of household waste, the concentration of mercury in the soil will exceed safety standards when this waste is landfilled. If waste batteries are mixed with household waste and enter the incineration plant, the harmful substances in the waste batteries will gasify at high temperatures, causing environmental pollution and affecting human health. Although batteries seem to contain many hazards, they are only left untreated and do not pose any harm during normal use.
