Learn about electricity – why should not the battery be fully charged and discharged? / Article / LSM.LV

The world is trying to improve the energy storage capacity of the battery. Kristaps Vitols, a researcher in Latvia, is also dealing with this problem. In LTV broadcaster Cognitive Impulse, he said the battery life should be fully charged and not completely discharged.

What was the victory of civilization in return for electricity?

  • In the 6th century BC Ancient Greece. York rubbed wool on wool and found static electricity.
  • In 1771, Italian physician Luigi Galvani observed that the bar was stepped on when the legs were spinning.
  • In 1800, Italian physicist Alesandro Volta built his first electric battery.
  • In 1820 André Marie Amper understood how the magnetic field is now affected.
  • In 1831, Michael Faraday discovered electromagnetic induction and laid the foundation for the creation of electric motors.
  • In 1879, American inventor Thomas Edison patented the first incandescent lamp.

When Faraday breaks out to his prime minister, the politician asked him what he was using. Then Faradey decided – I do not know, but I am sure it will be possible to collect taxes.

On the other hand, the legendary character of Nicolas Tesla in another science was done in a different way. He had the idea of ​​giving electricity to everyone free of charge. Tesla's basic idea is that an object in the city produces electricity, but a light bulb or other non-wire electrical equipment receives the energy it needs. The problem was very few users. So the Tesla Reel idea seems to be an expensive and inefficient way of supplying electricity to the consumer at least. Who knows, perhaps the idea of ​​electricity that can be used with the wireless Internet is not the right time.

The idea of ​​James M. Maxwell is much more effective. His idea of ​​how moving magnets generate electricity has made great strides in the development of civilization. Magnets move electrons like water. However, exactly the same electricity is often used for such comparisons, and where there is water, there are all units of measurement associated with current or present.

Basic Principles of Electrophysics

So what is the flow of electricity? This is electrons – small particles in small atoms. To understand why electrons are like electricity, you have to keep in mind the basic principles of physics.

Physicists describe electrons like a ball, which can not be neglected at all, but still has the power to pull, but unlike others, it has very strong rejection. Since electrons without electrons have different particles, protons, they interact with each other. Usually, many electrons in an atom are not protons and do not feel a special electrical discharge. For example, if one surface is rubbed with another surface, electrons are taken from one surface to another, and then particles of other particles are attracted when the number of particles changes. And all this can be measured by electricity.

Charges can be transferred from one surface to another. For example, this happens every time hair is released. Synthetic sheathing occurs even when the bridge touches the ground with metal objects.

The electromagnetic field, on the other hand, decides whether the electrons will move to the bridging river to form a direct current or fly 50 times per second to generate alternating current.

Explore energy storage devices

All types of electricity except for the current solar energy generate AC. However, only DC can accumulate. Direct current is the form in which energy is stored in the battery, and the type of battery is as varied as the operation of the device and the accumulation of the produced energy.

How long and how long the battery can store energy depends directly on the chemical elements in it. Battery chargers, on the other hand, affect the behavior of these elements. "As we accumulate energy, some ions move from one side to the other, and electricity does not flow in. When charging the battery, the ions are aligned and waiting on the other side. So, they are at the second equilibrium point, "explains Kristaps Vitols, a researcher at the Institute of Industrial Electronics and Electrical Engineering at Riga Technical University (RTU).

If the battery is empty or does not perform the operation, the particles will not stand in the correct position because they will not perform the required reaction again. "It's not good to throw away the battery completely because the ions went to the other side, so they settled in their place, and the longer they stay, the longer they stay in. Then the capacity of the battery starts to decrease. No, it can not work for a long time, "says Vitol.

In other words, the battery should not be fully charged and fully discharged. "In one case, the ions remain on one side and the other side remains on the other side.

These two extreme points weaken the battery, "the researcher explained.

Until recently, the battery should not have been partially recharged. Because they remember figuratively their condition, they are not fully charged. It turns out – this is neither myth nor truth. Because everything is in it where the battery is made. "Products built into devices such as lithium-ion batteries have no memory effect. In the past, there was a nickel-cadmium battery, which is remembered to work only half when charged," Vitol says.

The world can not make millions of dollars in this industry to further improve the battery's ability to store energy. Kristaps Vitols in Latvia is one of the scientists looking for the best battery solution. "There is no electronics, and the combination of chemistry and science in materials has allowed batteries to last longer. When they are implanted, the cells must be combined with a plan to manage the welfare of each cell," the researcher explained.

The battery's charge depends on the temperature, but it must be able to move in order to have the accumulated electrons.
