First, the battery type and composition: we all know, the battery laptop battery ACER Laptop Battery is the use of chemical energy, internal energy, solar energy, nuclear and other forms of energy into electrical energy, and in people's daily lives in a wide range of applications. At present batteries can be divided into the following five categories: dialogue among school cell alkaline batteries, micro batteries, dry batteries, the most exposure. Battery is the most common chemical batteries, with representatives of carbon-zinc dry cell battery as an example: carbon-zinc battery electromotive force of about 1. 5v, its surface is made of zinc cylinder. However, in order to increase the toughness and strength of zinc tablets, zinc tablets reduce the corrosion to extend battery life, the film joined aluminum zinc, cadmium, Gong and other substances. As the zinc-anode, electrolyte containing paste, the ingredients are ammonium chloride and starch. The middle of an electrolyte containing manganese dioxide as cathode coated carbon rod, and then sealed with a bitumen seal, so that electrolyte will not dry up. When the battery is receiving circuit, the negative electrode zinc release electronics, as ion zn2: zn-2n = zn2 electrolyte Eucalyptus as ammonium ion by electron gas and ammonium: nh4 + = h + +2 e = 2h + nh3; while dioxide manganese from the polarization effect, out of hydrogen, alkaline batteries and micro batteries are now more popular battery. Alkaline battery electrolyte is alkaline solution to a common alkaline batteries, for example, potassium hydroxide electrolyte, the anode is zinc powder with the powder, scrap battery is pressed a layer of manganese dioxide copper shell. Micro-battery Dell Inspiron 1721 battery Dell Inspiron 1300 BatteryDell Inspiron 1520 Battery Dell Latitude D600 Battery is represented by the button-type silver-zinc batteries, zinc as a negative electrode, silver films as a cathode. Alkaline batteries and micro batteries and dry cell works similar.
Second, the hazards of waste batteries: batteries on the analysis of available materials, chemical batteries are contained tribute, cadmium, lead, nickel, zinc, copper and other heavy metals. According to experts, used batteries in a battery with 50-100mg of the tribute, once mixed with the mercury batteries in groundwater or drinking water may enter the body through the crops, damage people's kidneys. Even more dangerous is mercury in water, mercury in water, due to the role of micro-organisms, inorganic mercury into methyl mercury accumulation, were enriched through the food chain, making the water contaminated by mercury, methyl mercury in fish than in water High on the times. Once people use the fish too much, methyl mercury into the human body would. Also Dell Inspiron 4100 battery Dell Inspiron 4000 battery Dell Inspiron 8200 battery Dell FK890 battery , because methyl mercury easily absorbed, easy to degradation and excretion, easy to accumulate in the brain, which makes the nervous system is seriously damaged, heavy death were crazy. Therefore, the battery in the tribute of pollution can not be underestimated. Relevant information that a fingernail-sized button battery waste, can contaminate 600,000 liters of water; a 1 battery rot in the ground, one square meter of land vegetation can not rise. It is indeed very shocking.
