Internationally accepted approach used batteries roughly three ways: curing buried, stored in a mine waste recycling.

(5) lead-acid battery lead-acid battery is the world's largest output, the most widely used kind of battery current. Sales accounted for more than 30% of the global battery sales. Our lead-acid battery annual output of nearly 30 million kWh. Pollution such batteries are mainly lead and heavy metal contamination of the electrolyte solution. Lead can cause nervous system neurasthenia, numbness, symptoms of indigestion, blood poisoning and kidney damage and other digestive system.
Discard a large number of waste batteries in the environment in which the acid, alkali electrolyte solution will affect the pH of the soil and water, the soil and water acidity or alkaline-based, and after mercury, cadmium and other heavy metals are absorbed creatures, through a variety of ways to enter the human food chain, gathered in the human body, the body teratogenic or mutagenic, or even lead to death. A button battery can contaminate 600,000 liters of water, equivalent to the amount of water a person's life. A battery rot in the ground, can make one square meter of land lost value. The greatest threat to the natural environment five kinds of substances, the battery inside it contains three kinds.compaq laptop batteries

Contamination of waste batteries
Civil batteries are currently using the largest, most decentralized battery products, domestic annual consumption of 8 billion. There are two series of zinc-manganese and alkaline manganese, zinc as well as a small amount of silver, lithium and other varieties. Manganese batteries, alkaline manganese batteries, silver-zinc batteries are normally used mercury or mercury compounds as corrosion inhibitors, mercury and mercury compounds are highly toxic substances. Waste batteries as domestic waste incineration, the part of the heavy metal waste batteries Hg, Cd, Pb, Zn, etc. into the atmosphere at high temperatures, become part of the ash, secondary pollution generated.

Internationally accepted approach used batteries roughly three ways: curing buried, stored in a mine waste recycling.
Curing buried
Waste batteries are generally shipped to a special toxic and hazardous waste landfill, but this approach is not only too expensive but also wasteful,
Because there is still a lot of useful material can be used for feedstock.Laptop Akku and laptop batteries news online
Recycling of waste batteries
Most domestic use of industrial batteries for lead-acid batteries, lead batteries accounted for more than 50% of total costs, mainly taken pyrometallurgical, hydrometallurgical processes, and solid-phase electrolytic reduction technology. Plastic shell, can be regenerated, basically no secondary pollution. Material waste batteries
Small secondary battery using more nickel cadmium, nickel metal hydride and lithium ion batteries, nickel-cadmium batteries cadmium is one of the strictly controlled environment of heavy metals in lithium-ion batteries in the organic electrolyte, nickel-cadmium, nickel-metal hydride batteries copper base and auxiliary materials and other heavy manufacturing batteries, constitute pollution of the environment. Small secondary batteries are currently only a few hundred million of total domestic use only, and the majority of the volume is small, [1-2] the use of low-value waste batteries, coupled with the use of dispersion, the vast majority for garbage disposal, recycling its existence the cost and management issues, recycling, there are some technical problems.
2 Hazard Editing
Hazard (1) manganese batteries zinc-manganese batteries, the electrolyte solution is mainly mercury and acid, alkali and other waste contained therein may enter upon the environment caused harm. Heavy metals like mercury can lead to central nervous system disorders, is "Minamata disease" culprit Japan.
(2) zinc-silver button batteries, button batteries are widely used in electronic watches, calculators, hearing aids, etc., is that people are more familiar with battery varieties. Hazards such batteries is mainly harm from mercury, cadmium and silver caused. According to statistics, harmful substances produced by a button battery can contaminate 600,000 liters of water.
(3) battery, lithium battery (Lithium battery) refers to an electrochemical system containing lithium batteries (including lithium metal, lithium alloys and lithium ion, lithium polymer). Including a battery and a lithium metal, a lithium ion secondary battery. Because of its high cost, long storage life, wide operating temperature range, etc., are applied to watches, cameras, calculators, backup power, pacemakers, security alarms. Such cell damage is relatively small, its recycling, recovery of useful components mainly lithium.
(4) alkaline batteries alkaline batteries are silver zinc, cadmium and nickel, iron, nickel hydrogen batteries and other series. Nickel-cadmium battery is a battery is currently the most widely used battery series, but also focus on issues of environmental pollution, the cadmium is highly toxic substances with carcinogenic, and nickel also has carcinogenic to aquatic organisms significantly dangers. According to the US EPA survey, waste cadmium nickel-cadmium batteries account for 75% of municipal solid waste cadmium total.
