Application of batteries and their variants
Devices capable of accumulating electricityand serve as its temporary source, have long been included in our everyday life. The use of batteries depends on the main parameters of the device, such as capacity, durability and size. Of course, each manufacturer invests in its devices proprietary developments, so the batteries have not only external, but also technical differences. HoweverThese features do not prevent us from dividing the drives into several main types.
Lead-acid batteries consist of a pairlead plates-electrodes, dropped into the electrolyte from sulfuric acid and water. Plates of nickel-cadmium elements are rolled into the tube and separated by an insulating material with electrolyte impregnation. Nickel metal hydride batteries differ from nickel-cadmium electrolyte solution composition and electrode material. The components of the lithium ion storage are placed in a solution of lithium salt.
In recent years, two more species have been inventedbatteries. In the lithium-polymer element, a polymer film is used instead of the liquid electrolyte. Typically, these batteries have a high charge density and very small dimensions. Due to these qualities, similar batteries are used in small-sized devices, for example, in telephones. The second new type of steel gel batteries. The role of the electrolyte in them is silica gel. This gelatinous, slightly dried layer between the electrolytes is permeated with honeycombmicroscopic cracks. Substances evaporated by electrolytes are absorbed into the gel and converted into a liquid. Thus, most of the harmful fumes remain inside the battery.
Use of batteries in any areadepends not only on their types, but also on the capacity of the devices. Both the conventional battery and the auto accumulator, this basic parameter is calculated in the same units, ampere-hours. So, a capacity of 800 mAh means that this battery provides 800 mA of electricity per hour. Another important parameter of the battery is the number of recharge cycles. The larger this number, the longer the device will last.
In addition to internal components, allThe electric accumulators differ in the field of application. Household elements include different types of batteries and ultra-thin laptop batteries and tablets. Industrial batteries, as a rule, are secondary sources of electricity andare used as a substitute for a fixed power grid. Typically, these batteries consist of several pairs of electrolytes connected in series. This type includes both car batteries and powerful devices that "straighten" the electric current. All industrial energy storage is divided into four categories. Stator batteries are used to start transport engines, stationary ones support the power supply of rectifier devices, traction batteries provide power for electric cars, portable "feed" measuring equipment. The use of batteries of industrial type, as a rule, is carried out in factories and other industrial enterprises. Powerful batteries provide power to machine tools, forklift trucks and other large equipment.
The production of batteries is constantly evolving. New types of miniature, capacious batteries that do not harm the environment are being invented. The use of batteries with new technologies makes modern life more comfortable and more mobile.
