Battery Type: Disposable batteries are mainly batteries
Battery Type: Disposable batteries are mainly batteries, secondary batteries and car batteries. Disposable batteries including button batteries, ordinary batteries and alkaline manganese batteries, disposable batteries and more mercury. Secondary battery mainly referring to rechargeable batteries containing cadmium. Automotive Waste Batteries contain acid and heavy metal lead.
3. Number of cells: DC, MP3 and other digital products to a whopping speed of development, but are using the battery, battery usage is rapidly increasing, if we do not put into action, the battery will happen sooner or later the phenomenon of the mountain.
Waste battery looks modest, but the harm is great. If you know the battery contains mercury, cadmium, lead and metal material damage, you also know that waste batteries much.
The hazards of waste batteries battery

Battery harm to the environment is mainly acid, alkali and heavy metal pollution of electrolyte solution. Pollutants in different types of batteries are also different.
In general, the battery of harmful substances mainly Zn, Hg, CNi, Pb and other heavy metals; of lead batteries in the H2S04; a variety of alkaline batteries and lithium batteries in IiPP6 KOH electrolyte. Hg and its compounds, especially organic mercury compounds, has strong toxicity, bioaccumulation faster rate and a longer biological half-life of the brain organ. Easy Cd accumulation in plants and animals, affecting the growth of plants and animals, is highly toxic. Pb on human breast, kidney, reproductive, cardiovascular and other organ and system adverse effects, manifested as mental retardation, kidney damage, infertility and high blood pressure. Zn, Ni toxicity is relatively small, but over a certain concentration range, would cause adverse effects and hazards. Used batteries in acid, alkali solution will affect the soil quality benefits of the pH value of water to soil and water acidification or alkalization. Battery electrolyte composition of pollution is one of the major components of soluble heavy metals, particularly lead-acid battery electrolyte of sulfuric acid in a large number of lead and nickel-cadmium batteries cadmium hydroxide. Battery of heavy metal ions in soil or water soluble and are absorbed by the roots of plants, when the animals to plants Siliao, the body will accumulate heavy metals. Human cannibalism food containing heavy metals, vegetables and meat, water, along the food chain, and heavy metals in the body will be enriched. As the heavy metal ions in the body is difficult to excrete, eventually damage the nervous system and liver function.
Recycling of waste batteries
2.1 Reuse of Waste Batteries
Most domestic use of industrial batteries lead acid batteries, lead batteries account for more than 50% of the total cost, mainly pyrometallurgical, hydrometallurgical process and electrolytic reduction of solid phase technology. Shell is plastic, can be regenerated, basically no secondary pollution.
