Why do batteries sit down?

How electricity is generated is more or less represented by each person familiar with the course of physics in high school. However, as we know, there is no electricity in batteries. So, on what basis do they work, and why do the batteries sit down? This is what we will try to explain today.

How batteries work

Batteries contain chemicals that have a unique potential for generating electricity. When we insert the battery and turn on the device, these chemicals react and create electricity. This is due to the fact that electrons pass from one atom to another, creating a flow of electrical energy on the microscopic scale of the atom. If a large number of atoms join, then the electrons go in different directions. In batteries, the most commonly used atoms of zinc, manganese, lithium, nickel, lead, cadmium. For example, zinc atoms donate electrons, and accept manganese.The characteristic of the force with which atoms give up their electrons is voltage.

Why the battery is discharged

The magnitude of the voltage in batteries depends on different combinations of atoms, because their activity is unequal. The battery sits down when all the electrons are finally transferred from one group of atoms to another. However, there are such batteries that can be recharged (for example, lead batteries of cars, or nickel-cadmium batteries), that is, to direct the process of electron transfer in the opposite direction. If you are concerned about the question of why batteries of this type are discharged, then the point is that with frequent recharging, the battery (especially its internal part) gets mechanical damage. That is why eternal batteries do not yet exist. Now you know why the batteries sit down. To learn more about this and in more detail, study the sections of physics that are devoted to various energy production from chemicals.
