The battery is used to power machines and devices for work through a set of electrical cells in the battery that generate electric currents. We use the word battery to describe a group of carp devices invented by benjamin franklin in 1748.

Alessandro Volta was the first to tell electrochemical and voltage batteries in 1800. Although the early batteries were of great value for experimental purposes, they were turned upside down during the use of currents for daniel’s cell, and in 1836 British pharmacist john Frederick daniel invented the first scientific source of electricity like a battery.

Types of Batteries


It is a device consisting of two or more electrochemical cells, and the principle of its work is to convert the chemical energy stored into electrical power. And this battery contains two compartments, one negative and the other positive; the latter is the source of electrons when connected to the outer circle through the flow and delivery of energy to the external system.

And when the battery remains connected to the outer ring. The electrolytes can move within the battery like ions, and there are many shapes and sizes for this type; two types:

Primary batteries are most common in mobile devices. They retain power for a long time and can recharge securely because active chemical reactions are difficult to return to their original form.
Secondary batteries: they are rechargeable batteries again.

Manufactured using liquid electricity technology through an unsightly container, which requires the battery to remain upright, and a well-ventilated area to ensure the safe dispersion of hydrogen and gas produced during overcharging.

Car Battery

It is a rechargeable species, supplies electric power to cars, controls the engine, lights, and ignition system, usually made with acid lead, lead dioxide, sulphuric acid, and water, consisting of six gulf cells, and can recycle car batteries, this reduces the need for resources to manufacture new batteries while protecting the spread of toxic bullets in landfills as improper disposal.

Liquid car battery liquid or lead battery, one of the most commonly used accumulators in cars, consists of an outer shell: an external object made of compressed rubber, divided from the inside into rooms called cells. These chambers contain plates.

Top cover: They make it of compressed rubber. Its function is to protect the internal battery parts from external factors. Several openings have the same battery cells to fill the battery with a solution. Plates: mesh-like panels, including vacuums filled with active material, divided into positive sheets, dark brown, fill the voids of lead-positive panels, negative sheets, gray, and reload the voids of lead-negative panels.

Insulating panels: made of insulating material such as plastic. These panels separate the positive and negative panels so that the smooth surface is opposite to the negative plates. While the surface of grooves is opposite to the positive plates. And the insulating plates are porous, to allow the solution to pass through the panels. Lead accumulation: you have to add diluted sulphuric acid solution to the accumulated, covering all panels.

Lithium Battery

These types have a three-letter abbreviation, lib. Commonly used in portable electronic devices, an excellent alternative to acid lead batteries, initially used for golf carts and vehicles. Thanks to the proposal of their manufacture to ms Whittingham of Binghamton University. They have made several modifications to their manufacture, most recently in 2014.

battery Mechanism

Discharge phase: it is the conversion of chemical energy into electric power by connecting an electric load with the battery. By consuming part of the electrical power stored in the battery, thus separating SO4 found in sulphuric acid from hydrogen.

And its association with lead on both plates, consisting of lead sulfate, while the oxygen atom and hydrogen combine, forming the water molecule. And at the end of the discharge phase. The solution becomes water. While positive and negative plates consist of lead sulfate.

Charging phase: it is to convert electrical power into chemical and restock it in the battery, by connecting the battery with a charging source. Thus degrading the water molecule into oxygen and hydrogen. And separating SO4 lead is associated with hydrogen so that the solution becomes made up of sulphuric acid. And the plates are made up of information.
