Why Can’t We Charge the Phone Battery Instantly?

our phone or computer when we need it most. run out of chargecan leave us in a rather helpless situation. So much so that the fact that the phone batteries only take 1 day is comforting, on the other hand, they are used 2-3 times a day. charging Being forced to do it gets on our nerves.

Even if there are fast charging options, why do phones usually have to charge their battery? for hours do we have to wait? Instead, let’s transfer all the energy that the phone needs to the battery, as if we were getting fuel for our car. 2-3 minutes Can’t we have a fully charged battery in it?

First of all, let’s solve the most fundamental misconception: Phone batteries are not tanks into which we fill electric current.

If they were anyway, your phone would noticeably droop when you run out of charge. it would be light. Rather inside the batteries, actually chemical reactions is happening. Even now, the reaction in question is taking place while you are reading this content.

This reaction takes place in two ways, when charging and discharging:

In both cases, anode and cathode are used. The conductivity between them is electrolytes provides. During charging, the cathode gets a negative value, while the anode gets a positive value. In the meantime, electrons are exchanged. When you plug the device into the charger, you reverse the chemical reaction that occurs when you use the phone. The roles of anode and cathode are thus changed.

In short, one click away from charging electricity to the phone and spending it as you use it. more complicated things are turning. Let’s continue with the simplest form though.

It is not possible for this reaction to occur all at once.

This is where the action-response rule comes into play. Let’s try to visualize it in your mind. On a road where there is no traffic, you can drive at any speed with your vehicle. resistance You can proceed without seeing. But if the road is full, you will not be able to go that fast as there will be a resistance in front of you. Or results it will be bad.

Electrons traveling on the battery, while you charge the device and use it after unplugging it. in motion It is possible. Meanwhile, from the conductor they are on, with resistance they face. This also generates heat, which is why we feel the phone getting hot when charging it as well as when using it for normal daily work.

This resistance exists because of the limitations of today’s technology. Well, let’s say we still give the phone the current it needs for a full charge, what happens?

If twice the current is supplied to the phone than normal, the electrons will be lost again because of the resistance. double will generate more heat. 1 hour full battery in 1 minute When we try to fill it, this means compressing the load that can be taken in roughly 60 minutes to 1 minute. It is clear what will happen as a result.

At this point in your mind, Samsung’s exploding phone Galaxy Note 7 may have come. Normally, lithium phone batteries have circuits to prevent overheating. enough for these circuits to dissipate heat effectively. wide area they must have. This was also the issue where the Note 7 was missing and disastrously, it didn’t offer enough room for the circuitry and therefore was incapable of dissipating the heat.

Another important purpose of the circuit in question is to prevent thermal leakage:

This situation reduces the heat of the heated system. by not distributing and therefore there is even more by feeding repetitively causing it to burn. In other words, as we have just said, the high amount of current given to the phone instantly will cause such a reaction and make the device unusable.

But in such a case, you don’t have to worry about your device. Because your hospital expenses will be more noticeable.

A method has recently been discovered that will quickly charge the batteries:

As a result of this study, which focused on electric vehicles, a method was found to solve the problem of lithium-ion batteries overheating under heavy load. Those who perform the work, for the battery wider Of course, they didn’t think of using a space. Instead of machine learning problems are expected to be solved.

Within the scope of the said study, the researchers used batteries for all types of batteries. unharmed how is the charging time can be optimized and saw which charging methods different batteries would cause problems. In the method used as a result of the analysis, the charging of an electric car battery percent 0 to 90 in just 10 minutes removed.

When we see this becoming widespread, it is an undoubted fact that electric vehicles will gain strength in competition. On the other hand, we expect to see the same development in smartphones.
