The world is trying to improve the ability of the battery to store energy. Latvian researcher Kristaps Vitols also deals with it. In LTV broadcasts, Cognitive Impulse, he says battery life should not be fully charged and completely empty.
How is the victory of civilization in exchange for electricity?
- 6th century BC in ancient Greece. Ike found static electricity by rubbing a piece of amber against the wool.
- In 1771, an Italian physician, Luigi Galvani, discovered that the rod was rolled over when it was rolled over.
- In the 19th century, Italian physicist Alesandro Volta created the first electric battery.
- In 1820 André Marie Amper understood how the current magnetic field works.
- In 1831, Michael Faraday found electromagnetic induction and created the basis for creating an electric motor.
- In 1879, American inventor Thomas Edison patented the first light bulb.
It is said that at a time when Faraday was a breakthrough for the country's prime minister, the politician asked if he had any use. Faradey determined at the time – I do not know, but I am convinced that it is possible to collect taxes.
At the same time in another known Nicholas Tesla's legendary personality went a different way – he had the idea of making electricity free for everyone. The basic idea of a Tesla roll is that an object in the city center generates electricity, but incandescent bulbs or other non-electrical electrical appliances receive the necessary energy from it. The problem was that the number of users was very small. Thus, the idea of the Tesla Roll seems to be now a rocky and inefficient way of supplying electricity to consumers. Who knows, maybe electricity availability over the Internet is not the right time.
Much better with James M. Maxwell to make his idea work. His idea of how the moving magnet generates electricity has made a big breakthrough in the development of civilization. The magnet moves electrons such as water. Otherwise, the same electricity is often used for such a comparison, and if there is water there is also current or current and all related units of measurement.
Basic principles of electrical physics
What then is the flow of electricity? These are electrons – small particles in small atoms. Some basic principles of physics need to be kept in mind in order to understand why electrons make up electricity.
Physicists reflect electrons such as balls, all of which have very small but still appealing forces, but unlike others, there is a very strong rejection force. Because the atoms, which have no electrons, also have other particles – protons, they interact with each other. In general, how much the atom does not have a proton, so much electron, and we do not know any specific emissions of electricity. For example, when rubbing one surface to another, we get electrons from one surface to another and the number of particles changes, they start to attract the particles of other objects. And all this can be measured by electricity.
Electric charges can be transferred from one surface to another. For example, this happens every time the hair radiates, synthetic clothes even if they pull the feet to the ground and touch metal objects.
Instead, the electromagnetic field controls the electrons moving in bridges and forming a direct current or flying 50 times per second and generating alternating current.
Investigating Energy Storage
All existing electricity generating methods, except solar energy, generate AC power. However, only direct current can be accumulated. Direct current is a form where energy is also stored in batteries and the battery types are as different as their tasks: the use of devices, the generation of energy.
How and how long the batteries can store energy, depends directly on their chemical elements. On the other hand, the battery charger affects the operation of these elements. "At the moment when we collect energy, some ions move from one side to the other, and no electricity is in. When you charge the battery, the ions are directed to the other side and wait, we connect an external load and the current starts to flow in the opposite direction and the ions move backwards, "says researcher Kristaps Vitols, research institute of industrial electronics and electrical engineering at Riga University of Technology (RTU).
When the batteries are empty or fail to perform, they will not perform the required reactions again, so the particles will not stay in the right places. "There is no reason to throw the battery all the time, as the ions have gone to the other side, they have settled in, and the longer they are there, the more they hold there, the batteries then begin to drop capacity, it can not accumulate so much and it can not function so long, says Vitol.
This means that the battery is not fully charged and fully emptied. "In one case, the ions stay on one side and the other on the other side.
Both extremes weaken the battery, "the researcher says.
Not so long ago it was believed that batteries should not be partially recharged because they resemble their imagination and have not at all attempted to be full. It turns out – this is not a myth or a truth, because everything is where the batteries are made. "Built-in devices, such as lithium-ion batteries, have no memory effect. Previously, nickel-cadmium batteries were reminded – if they were half charged, then only half worked, Vitol says.
To further improve battery recovery, the world does not produce millions in this industry. In Latvia, Kristaps Vitols is one of the scientists who are looking for the best battery system to care for them just like a living organism. "There is no electronics, but chemistry and material sciences that are packed for longer, better and cheaper. Once transplanted, cells have to be combined with systems that cater to the well-being of each cell," says the researcher.
The battery's abundance depends on the temperature, but in order for the electrons to accumulate they must be able to move.
