What is Battery:
The term battery can refer to a device that is capable of generating enough electrical energy to activate other objects such as flashlights, cell phones and cars, a percussion instrument, or it is also used to refer to a set of cooking utensils.
The word battery derives from the Latin verb battuere which means "to hit."
Originally, the word battery indicated tools forged by blows later, it was used to indicate an artillery set and at the end of the 18th century, Benjamin Franklin (1706-1790) coined the term battery to refer to “a set of connected units capable of discharging power ”.
Battery or electric cell
The battery, also called a cell or accumulator, is a mechanism of one or more cells with 2 poles or electrodes that in contact with a conductive liquid (electrolyte) is capable of producing electrical energy.
Batteries are called electrical because they produce electrical energy through the chemical energy of the ions that pass between the poles or electrodes.
Electrodes contain a limited number of units of chemical energy that can be converted into electrical energy. In this sense, rechargeable batteries use materials that allow reversible reactions for the battery to release and, in turn, accumulate energy.
The size, number of cells and materials of the batteries or cells will determine if the amount of electromotive force (measured in volts) and electrical current (measured in amperes) will be sufficient to be transmitted to the objects to be charged with electrical energy.
Drums and Alessandro Volta
The Italian chemist Alessandro Volta (1745-1827) is the inventor of the first voltaic pile, also known as the Volta pile.
In 1800, Alessandro Volta presented to the scientific community a mechanism with 30 copper and zinc discs separated by wet cloths, which would produce direct current.

Batteries in cars work on the same principles as electric batteries in a toy, lithium batteries in a cell phone, or a computer.
The car battery is composed of 6 cells of 2 sets of electrodes. Each cell generates 2 volts of power which gives a total of 12 volts, enough electrical energy to start the motor, its main and most important function.
Like all batteries, the electrodes or poles have a positive and a negative side. The positive releases energy while the negative accumulates it. The material that covers the cells is generally lead and lead oxide, thanks to its electrical conductivity.
On the other hand, the cells are submerged in 35% sulfuric acid and 65% water, which constitutes the electrolyte of the battery, that is, the substance that conducts electricity.
The French scientist Gastón Planté (1834-1889) is the inventor of the first battery capable of recharging its cells through reversible reactions. Its lead-acid battery dates from the year 1860.
In this way, the batteries or cells present in most of the electronic devices that we use every day, have changed the way we use energy and technology.
