With the social

With the social and economic development, various electronics and communications equipment in large numbers, replacement continues to accelerate dell laptop battery and make people use in their daily lives the number and types of batteries is increasing dramatically. According to incomplete statistics, China's lead-acid battery manufacturer, has reached around 1500, producing an average annual rate of about 20% of the high-speed growth. In 2007, China's battery production reached 33.7 billion, exports amounted to 25.168 billion, the battery output has exceeded more than half of world production.

Recovered a large number of untreated hazardous waste batteries great

Waste dell Inspiron 630m battery may be small, against Queshen big. China has become the production and consumption of battery power, so battery waste pollution is an urgent need to address a major environmental problem. Waste batteries are mainly harmful to the environment of harmful components of the cell after the pollution caused by discarded batteries. Batteries harmful ingredients are mainly mercury, cadmium, nickel, lead and heavy metals, in addition to acid, alkali and other electrolyte solution, harmful to human and ecological environment in varying degrees of harm. It is understood that, in which the environment on human health and ecological hazards greater control of the List of hazardous waste to include scrap batteries are: mercury batteries (primarily mercuric oxide batteries), lead-acid dell Inspiron 640m battery, cadmium batteries (mainly nickel-cadmium batteries ).

One of the environmental hazards of waste batteries

1.1 The types of batteries and harm

(1) zinc-manganese batteries

Zinc-manganese dry dell Y9943 battery of the hazards, which are mainly contained mercury and acid, alkali and other electrolyte solution was discarded into the environment of the possible harm caused. Heavy metals like mercury can cause central nervous system diseases, which Japan's "Minamata disease" culprit.

(2) button cell

Button-type zinc-silver dell RC107 battery are widely used in electronic watches, calculators, hearing aids and so on, is that people are more familiar with the battery variety. Such batteries are also mainly by the dangers of mercury, cadmium and silver hazards. According to statistics, a button battery produces harmful substances can contaminate 600,000 liters of water.

(3) lithium batteries

Lithium battery is used as anode materials for lithium batteries collectively referred to each series, including a battery and lithium metal, lithium-ion secondary battery. Because of its cost-effective, storage, long life, wide operating temperature range, etc., have been used in watches, cameras, calculators, back-up power supply, cardiac pacemakers, security alarm and so on. Type of battery against a relatively small, its recycling, recovery is mainly a useful component of lithium metal dell Latitude D620 battery.

(4) alkaline batteries

Alkaline batteries are zinc-silver, cadmium, nickel, iron, nickel, nickel-metal hydride battery series. Nickel-cadmium battery is currently the most widely used battery series, is also a focus on environmental issues as a dell PC764 battery, cadmium is highly toxic substances that are carcinogens, but also has the carcinogenicity of nickel, for aquatic organisms has obvious dangers. According to the U.S. EPA survey, discarded Ni-Cd battery of cadmium in municipal solid waste accounts for 75% of the total cadmium.

(5) lead-acid batteries

Lead-acid battery is the world's production of the largest and most widely used as a battery. Global battery sales account for more than 30% of sales. China's annual output of nearly 30 million lead-acid batteries kWh. Contamination of these batteries are mainly lead and heavy metals contamination of the electrolyte solution. Lead can cause nervous system neurasthenia, hand, foot and numbness, digestive system, indigestion, blood poisoning and kidney damage and other dell TD175 battery symptoms.
