The heavy metal salt, acid and alkali and other substances contained in the waste battery of electric bicycle are hazardous wastes. The pollution caused by them has the characteristics of long period, high concealment, and serious influence and so on.
The waste batteries contain heavy metals, such as mercury, lead, cadmium, nickel and electrolytes such as acid and alkali, which are harmful to human body and ecological environment.
What are the harmful substances in the waste batteries? The waste batteries contain heavy metals, such as mercury, lead, cadmium, nickel and electrolytes such as acid and alkali, which are harmful to human body and ecological environment. These toxic substances enter the human body through various channels, long-term savings are difficult to rule out, will harm human health.
The environmental pollution of waste lead storage battery is mainly controlled by harmful substances such as Pb (Pb), CD (CD) and electrolyte solution. Lead acid batteries pollute the electrode plate for hundreds of times, which leads to the battery being unable to recharge and scrapped. The waste lead acid battery usually contains 20% of electrolyte, and the mass concentration of PB is as high as 710 g / l after static clarification.
Many enterprises add CD to lead battery production to prolong battery life, and CD element is more harmful to the environment. The International Cancer Research Agency classifies CD as category I human carcinogen, which makes lead-acid batteries more polluted.
