The world is working to improve battery capacity to store energy. Kristaps Vitols, Latvian researcher, also deals with this. In the LTV transmission, Cognitive Impulse, he says that the battery life must not be fully charged and totally discharged.
How was the victory of civilization in exchange for electricity?
- 6th century BC in ancient Greece. The yoke discovered the static electricity rubbing a piece of amber against a la.
- In 1771, the Italian doctor Luigi Galvani observed that the rod was stuck in the leg when he helped him.
- In 1800, the Italian physicist, Alesandro Volta, created the first electric battery.
- In 1820, André Marie Amper understood how the current magnetic field is affected.
- In 1831, Michael Faraday discovered the electromagnetic induction and laid the foundations for the creation of an electric motor.
- In 1879, the American inventor, Thomas Edison, patented the first incandescent bulb.
It is said that, at a time when Faraday was showing an advance for the prime minister of his country, the politician asked him if he had any use. Faradey at that moment determined – I do not know, but I am convinced that it will be possible to collect taxes.
Meanwhile, in another science, the legendary personality of Nicolás Tesla was in a different way: he had the idea to make electricity free for all. The basic idea of a Tesla reel is that an object in the center of the city generates electricity, but the lamps or other non-electric electrical equipment receive the necessary energy. The problem was that the number of users was very small. So Tesla's coil idea at least now looks like an expensive and ineffective way of delivering electricity to consumers. Who knows, maybe the idea of electricity available as a wireless internet is not the time.
Much better with James M. Maxwell doing his ideas to work. Your idea of how a mobile magnet generates electricity is a breakthrough in the development of civilization. The magnet moves electrons like water. By the way, the same exact electricity is usually used for such comparison, and where there is water, there is also a current or current and all related units of measure.
Basic principles of electrical physics
What is the flow of electricity? These are electrons: small particles in the small atoms. It is necessary to take into account some basic principles of physics to understand why electrons form like electricity.
The physicists illustrate electrons like balls that, like any case, have, although they are very insignificant but still forces of attraction, but unlike other people, they have a very pronounced rejection force. Since atoms without electrons also have other particles – protons, they interact with each other. Normally, how long the atom does not have a proton, either of an electron, and we do not feel any special electric shock. For time, for example, when rubbing one surface against another, we obtain the electrons from one surface to another, and then the number of particles changes, they begin to attract particles from other objects. And all this can be measured as electricity.
Electric rates can be transferred from one surface to another. For example, this occurs every time emitting hair, synthetic clothing, even if it pulls the legs on the floor and touches metal objects.
The electromagnetic field, on the other hand, determines if the electrons will move like a bridge river and will form a direct current, or they will fly here 50 times per second, generating alternating current.
Exploring energy storage
All types of power generation currently available, except solar energy, generate an alternating current. However, only direct current can be accumulated. The DC is the way in which energy is also stored in batteries and the types of batteries are as varied as their tasks: operating devices, accumulating produced energy.
The way and how long the batteries are capable of storing energy depend directly on the chemical elements in them. The battery charger, on the other hand, affects the behavior of these elements. "At the moment we accumulate energy, some of the ions move from one side to another and the electricity does not flow inside. When charging the battery, the ions align on the other side and wait. We connect the external load, and the current starts to move in the opposite direction and the ions move backwards. That's why they are at the second point of equilibrium, "explains Kristaps Vitols, a researcher at the Institute of Industrial Electronics and Electrical Engineering at the Technical University of Riga (RTU).
When the batteries are empty or do not perform their task, they do not perform the necessary reactions again, so the particles are not placed in the correct places. "It's not good to take the battery all the time. Because then the ions have gone to the other side, they settled in their place, and the longer they are there, the more they like to be there. Then the batteries begin to fall into capacity. accumulate so much and can not operate for so long, "says Vitol.
This means that the battery should not be completely charged and fully discharged. "In one case, the ions remain on one side and another on the other side.
Both extreme points degrade the battery, "explains the investigator.
Not so long ago, it was believed that batteries should not be partially recharged, because then they figuratively remembered their condition and did not try to be full. It turns out that this is not a myth nor the truth, because everything is within what batteries are made. "Built-in devices, such as lithium-ion batteries, have no memory effect. In the past, there were nickel-cadmium batteries that reminded themselves if they loaded on average, then only half worked," Vitol says.
In order to improve the capacity of batteries to store energy, the world does not make millions in this industry. In Latvia, Kristaps Vitols is one of those scientists who, when looking for the best battery solutions, take care of them as a living organism. "There is no electronics, only chemistry and materials science, united to make batteries last longer, better and cheaper. When they are going to be transplanted, cells should be combined with schemes that take care of the welfare of each cell," explains or researcher.
The battery's wealth depends on the temperature, but to have electrons that accumulate, they must be able to move.
