The main hazards of battery products to the environment are the pollution of electrolyte solutions such as acids and alkalis and heavy metals. Different types of battery pollutants are also different. To

Generally speaking, harmful substances in batteries mainly include heavy metals such as Zn, Hg, CNI, and Pb; H2S04 in lead batteries; KOH in various alkaline batteries and IiPP6 electrolyte in lithium batteries. Hg and its compounds, especially organic mercury compounds, have extremely strong biological toxicity, faster bioaccumulation rate and longer brain organ biological half-life. Cd is easy to accumulate in animals and plants, affects the growth of animals and plants, and has strong toxicity. Pb has adverse effects on human organs and systems such as chest, kidney, reproduction, cardiovascular, etc., manifested as mental decline, kidney damage, infertility and high blood pressure. The toxicity of Zn and Ni is relatively small, but when it exceeds a certain concentration range, it will have adverse effects and harm to the human body. The acid and alkaline hydrolyzate solutions in the waste battery will affect the pH value of the soil and water system, making the soil and water system acidic or alkaline. The main component of battery electrolyte pollution is the soluble heavy metals, especially the large amount of lead sulfate in the electrolyte of lead storage batteries and the cadmium hydroxide in nickel-cadmium batteries. The heavy metal ions in the battery are dissolved in the soil or water and absorbed by the roots of plants. When livestock feed on plants, heavy metals are accumulated in the body. Humans cannibalize food, vegetables, meat, and water that contain heavy metals. Following this food chain, heavy metals will accumulate in the human body. Since heavy metal ions are difficult to excrete in the human body, they will eventually damage the human nervous system and liver function.
