Batteries :: essays research papers

BATTERIESThere be many kinds of batteries which consist of variant materials in order to produce an electric charge. Here argon almost of the most common batteries, what they consist of and how they work.Bichromate Cell (see impression 1)A stamp onslaught is a device which converts chemical energy into electrical energy. A battery usually consists of two or more cells connected in series or parallel, you can also convey a single cell battery. All cells consist of a positive electrode, and a minus electrode. An electrolyte is a liquid substance capable of conducting electricity. In this substance iodin of the electrodes will react producing electrons, while the other will except electrons. When the electrodes are connected to a device to be powered, called a load, an electrical stream flows.Batteries where the chemicals cannot be returned to their original form once the energy has been converted (that is, batteries that have been discharged) are called primary(a) coil cel ls or voltaic cells. Batteries in which the chemicals can be returned to its original form by passing an electric current by dint of them in the direction opposite that of normal cell operation are called secondary cells, rechargeable cells, storage cells, or accumulators.Dry Cell Battery(see picture 2)This is the most common battery that people use today wish well Energizer or Duracle batteries. The most common form of a primary cell is the Leclanche cell, invented by a French chemist Georges Leclanche in the 1860s. The electrolyte for this battery consisted of a mixture of ammonium chloride and zinc chloride made into a paste. The blackball electrode is zinc, and is the outside shell of the cell, and the positive electrode is a vitamin C rod that runs by means of the center of the cell. This rod is surrounded by a mixture of carbon and manganese dioxide. This battery produces about 1.5 volts.Another widely used primary cell is the zinc-mercuric-oxide cell, more commonly call ed a mercury battery. It can be made in the shape of a small flat track record and is used in this form in hearing aids, and electric wristwatches. The oppose electrode consists of zinc, the positive electrode is of mercuric oxide, and the electrolyte is a solution of potassium hydroxide. The mercury battery produces about 1.34 volts.The fuel cell is another type of primary cell. It is droll in that the chemicals arent contained within the cell but are supplied from outside of the cell.
