Issues for its polluting power, remain the main generator portable electric power.
The principle that operates in a pile stems from a chemical reaction was observed in year 1800 by the Italian physicist Alessandro Volta. Introducing two metals in various half-conductor of electricity such as water-dissolved salts, the flow of particles with positive charges that occurs creates a potential difference in metals, called electrodes. That difference makes it possible for the device to provides electrical power to an external system. Over time, uncomfortable aqueous conditions were replaced by dry, that are more practical, and copper and zinc were the most commonly used metals. With this approach, the English chemist Frederick Daniell invented in 1836 a stack dry marking its evolution and then became batteries saline zinc and coal, we now know as “normal cells.”
The alkaline or high performance are the most consumed: provide power, duration and contain mercury, which, unlike the saline makes pollutants.
Although they generate more environmental risk are button cells (clock), which contain a higher concentration of mercury. . The most modern are rechargeable, and employing nickel cadmium (also pollutant) and allow reconstitute its chemical system through internal current network, to restore the generative capacity.
As there are no facilities for collecting batteries, specialists recommend discarding gradually rather than combining as it could power its polluting power. Another option is to contact some NGOs to develop a recycling plan.
The wrong place
Luigi Galvani found in early 1800 that killed a muscle that shaken when they contacted with two different metals. The recital explained that electricity was involved in the phenomenon, but thought that originated in the muscle and not in metals.
How batteries polluting?
The polluting materials are heavy metals such as mercury and cadmium. In landfills, there is a significant amount of discarded batteries, and rain is responsible for transporting metals until the webs of water pollution. The remains of a single alkaline battery can pollute up to 175 thousand liters of water, and a stack type button, 600 thousand liters, so you want to use the rechargeable, while cadmium contributing to the environment, offer a much longer lifespan .
There is also a high risk of contamination in direct contact with the batteries. Taking into account the serious consequences caused by mercury, children should not manipulate any kind of batteries.
Are there non-polluting batteries?
Yes. Several companies are developing, although in Argentina there is no ecological choices in the marketplace. The Japanese Nopopo can be filled with any liquid (up with urine) for use:
no contaminan , not pollute, but its electrical capacity is low. Sony, meanwhile, is about to launch a biobatería that produces energy from carbohydrates, using enzymes as catalysts.
Is it true that in Babylon were used batteries?
An Austrian archaeologist found in Bagdadun object belonging to the Babylonian empire that related to a battery. . It was a ceramic container of 15 centimeters a cylinder containing copper at its base in contact with a sheet of tin. The discovery was the subject of multiple explanations without further scientific substantiation.
