Devices that can accumulate electricity and serve as its temporary source have long been included in our everyday life. The use of batteries depends on the basic parameters of the device, such as capacity, durability and size. Of course, each manufacturer invests branded developments in their devices, so the batteries have not only external, but also technical differences. Odnak
These features do not interfere with dividing drives into several main types.
Lead-acid batteries consist of a pair of lead electrode plates dipped into an electrolyte from sulfuric acid and water. Plates of nickel-cadmium elements are rolled into a tube and separated by insulating material with electrolyte impregnation. Nickel-metal hydride batteries differ from nickel-cadmium in the composition of the electrolyte solution and the material of the electrodes. The components of a lithium-ion electron storage device are placed in a solution of lithium salt.
In recent years, two more types of batteries have been invented . In a lithium polymer cell, a polymer film is used instead of a liquid electrolyte. Typically, these batteries have a high charge density and very small size. Due to these qualities, such batteries are used in small-sized devices, such as telephones. The second new type of gel batteries. The role of electrolyte in them is played by silica gel. This jelly-like, slightly dried layer between electrolytes is penetrated by honeycombs.
microscopic cracks. Substances evaporated by electrolytes are absorbed into a gel and converted into a liquid. Thus, most of the harmful fumes remain inside the battery.
The use of batteries in any field depends not only on their types, but also on the capacity of the devices. Both a conventional battery and an auto-accumulator, this basic parameter is calculated in the same units, ampere-hours. So, a capacity of 800 mAh means that this battery gives out 800 mA of electricity per hour. Another important parameter of the battery is the number of recharge cycles. The higher this number, the longer the device will last.
In addition to internal components, all electronic storage devices vary in scope. Household items include batteries of various types and ultra-thin batteries for laptops and tablets. Industrial batteries are typically secondary sources of electricity and
used as a replacement for a stationary power supply. Typically, such batteries consist of several pairs of series-connected electrolytes. This type includes both automobile batteries and powerful devices that “rectify” electric current. All industrial energy stores are divided into four categories. Stater batteries are used to start transport engines, stationary ones support the power supply of rectifier devices, traction batteries provide electric cars with energy, and portable ones “feed” the measuring equipment. The use of industrial batteries, as a rule, is carried out at factories and other industrial enterprises. Powerful batteries provide electricity to machines, forklifts and other large equipment.
Battery production is constantly evolving. Invented new types of miniature, capacious batteries that do not harm the environment. The use of batteries with new technologies makes modern life more comfortable and mobile.
