Learn about electricity – why should not the batteries be fully filled and empty? / Article / LSM.LV



The world works to improve the battery's ability to store energy. Kristaps Vitols, a researcher in Latvia, also deals with it. In the LTV broadcast, Cognitive Cognitive, says battery life should not be fully charged and full release.

How was a civilization victory in exchange for electricity?

  • 6th Century BC in Ancient Greece. The liver discovered static electricity by rubbing a piece of amber against wool.
  • In 1771, Italian doctor Luigi Galvani saw that the rod was turned into the leg when it was triggered.
  • In 1800, the Italian physicist, Alesandro Volta, created the first electric battery.
  • In 1820, André Marie Amper understood how the current magnetic field would be affected.
  • In 1831, Michael Faraday discovered an electromagnetic induction and laid the foundations for the creation of an electric motor.
  • In 1879, the American inventor, Thomas Edison, patented the first core bulb.

It is said that, at a time when Faraday showed priority to the prime minister of his country, the politician asked if he had any use. Trade decided at that time – I do not know, but I am convinced that taxes can be collected.

Meanwhile, in other science, the legendary Nicholas Tesla personality went differently – he had the idea of ​​making electricity for everyone. The basic idea of ​​the Tesla railway is that an object in the city center produces electricity, but light bulbs or any other wireless wire devices receive the necessary energy from it. The problem was that the number of users was very small. So, the idea of ​​Tesla's wheel at least now looks like an expensive and ineffective way of introducing electricity to consumers. Who knows, the idea of ​​electricity that is available as a wireless Internet may not be the right time.

Much better with James M. Maxwell making her ideas going to work. Its idea of ​​how a mobile magnet generates electricity has made great progress in the development of civilization. The magnet moves electrons like water. By the way, electricity is often used for comparison of this type, and where there is water, there are also current or current measurement units and all that are associated.

The basic principles of electrical physics

What is the flow of electricity then? These are electrons – small particles in the small atoms. Some basic principles of physics must be remembered in order to understand why electrons make up electricity.

Physicists depict electrons such as balls, which, as any case, have been, but very trivial, but attractive stations, but unlike others, have a very refusal force. Since atoms with no electrons also have other particles – protons, they interact with each other. Normally, there are not many in the proton atoms, so much electron, and we do not feel any special electrical discharges. By the time, for example, when rubbing one face against another, we will get the electrons from one face to another, and then the number of particles change, they begin to attract particles of other objects . And this can be measured as electricity.

Electricity charges can be transferred from one face to another. For example, this happens whenever hair is emitted, synthetic clothing, even if it removes legs on the ground and touches metal objects.

The electromagnetic field, on the other hand, determines whether the electrons move as a transitional river and will form current current, or will fly down here 50 times a second, producing current in second.

Explore energy storage

All current power generation types, other than solar energy, produce an existing series current. However, only direct current can be accumulated. Direct current is the way in which energy is also stored in batteries, and batteries are as diverse as their tasks: to operating devices, to build up energy generated.

Batteries can save energy directly depending on the chemical elements in them. The battery charger, on the other hand, affects the behavior of these elements. "At the moment when we collect energy, some of the ionities move from one side to another, and electricity does not flow inside. When lifting the battery , the plugs are aligned on the other side and are waiting. We connect the external load, and the current current flows to the other address, and & # 39; the ions are moving back. That's why they're on the second balance point, "explained Kristaps Vitols, researcher at the Electronic Technical Institute of Engineering and Electrical Engineering of the University of Riga (RTU).

When the batteries become vacant or fail to perform their task, they do not complete the required reactions again, so the particles do not stand in the correct places. "It's not OK to throw the battery through the road. Because the ions have gone to the other side, they have settled in their place, and they are longer there, po The more they like to stay there. The batteries are starting to fall. They can not accumulate as much and can not wait for a long time, "Vitol said.

This means that the battery should not be fully charged and full discharges. "In one case, the ions continue on one side of the other on the other side.

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

Not far back, it was thought that batteries should not be partially refurbished, because their condition was recorded figuratively and did not at all try to be full. It is evicted – this is not a myth or a story, because everything in it lies in which the batteries are made. "Those that are part of devices, such as lithium-ion batteries, have no memory effect. In the past, there were recycled nickel-cadmium batteries – if it were & # 39, being accused and half, only half worked, "said Vitol.

In order to improve battery capacity to store energy further, the world does not make millions in this industry. In Latvia, Kristaps Vitols is one of those scientists who, looking for the best battery solutions, looks after them just like a living organism. "No electronics, only chemistry and science materials, have been designed to make the batteries last longer, better and cheaper. When they are transplanted, cells must be combined with s & Look after the welfare of each cell, "explained the researcher.

The battery's richness depends on the temperature, but in order to have electrons that they accumulate, they must be able to move.
