BATTERIESThere ar many kinds of batteries which consist of different materials in order to produce an galvanizing charge. hither are some of the most common batteries, what they consist of and how they work.Bichromate cadre (see picture 1)A battery is a device which converts chemical vitality into electrical faculty. A battery usually consists of two or more kiosks connected in series or parallel, you can also keep up a single cell battery. All cells consist of a peremptory electrode, and a negative electrode. An electrolyte is a liquid substance capable of conducting electricity. In this substance one of the electrodes provide 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 current flows.Batteries where the chemicals cannot be returned to their original fix once the energy has been converted (that is, batteries that have been discharged) are called primary cells o r voltaic cells. Batteries in which the chemicals can be returned to its original form by passing an electric current through them in the direction opposite that of normal cell operation are called secondary cells, rechargeable cells, storage cells, or accumulators. dry out Cell Battery(see picture 2)This is the most common battery that people go for today like Energizer or Duracle batteries. The most common form of a primary cell is the Leclanche cell, invented by a French pharmacist Georges Leclanche in the 1860s. The electrolyte for this battery consisted of a mixture of ammonium chloride and zinc chloride do into a paste. The negative electrode is zinc, and is the outside shell of the cell, and the positive electrode is a carbon rod that runs through 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 wide used primary cell is the zinc-mercuric-oxide cell, more commonly called a atomic nu mber 80 battery. It can be made in the shape of a diminished flat disk and is used in this form in sense of hearing aids, and electric wristwatches. The negative electrode consists of zinc, the positive electrode is of mercuric oxide, and the electrolyte is a solution of super C hydroxide. The mercury battery produces about 1.34 volts.The fuel cell is another grammatical case of primary cell. It is unique in that the chemicals arent contained within the cell but are supplied from outside of the cell.
