The battery has been left for a while why is it charged again 5

Now we use chemical batteries, and I haven't seen bioenergetic ones.

Chemical energy is because the reaction produces the movement of electrons, and there is electricity. And when the chemical reaction is almost over, there will be no movement of electrons if there is no reaction, and naturally there will be no electricity at this time, and a small amount of electrons will be produced again after a period of time, because the chemical reaction cannot be thorough! There is always a little bit of rereaction, and if there are more electrons gathered, you will feel that the battery is charged again!!

In fact, the chemical effect is occurring inside the battery, and if the electricity is used too quickly, the battery electrolysis cannot keep up with the speed of use, and the battery will run out of power. After you stop using it for a while, the electrolysis reaction continues, and the remaining battery solids continue to release electricity, which will produce a certain amount of residual electricity.

Hope it helps!

Dry batteries have such a condition.

This is not the case with alkaline batteries and rechargeable batteries.

The reason is that the middle of the dry battery is a carbon rod, which has a chemical reaction with the material on the side, and a positive charge is concentrated on the carbon rod.

Or hit the battery 2 times with a heavy object, so that the material around the carbon rod is replaced immediately, and the battery will be charged immediately

There are many kinds of batteries!

But batteries are the result of chemical reactions! If the battery is not used for a long time, the internal chemical reaction will slowly accumulate, and the accumulated electricity will be released the moment you use it again.

As long as the chemical reaction inside the battery is not completed, the battery will always have power, but there is a problem of whether the power is sufficient!

Batteries are not full of positive and negative ions.

When the two ends are turned on, the anion moves to generate an electric current.

At the end of the chemical reaction, after the negative decomposition is completed, it is considered to be out of power.

But inside the battery. Any stable ionic compound is relatively stable.

The flow of electrons is also generated. So that's why there's electricity.

But this movement is very subtle due to the plain clothes of the keys.

Because the battery is re-concentrated in the process of cooling, but it is not released and there is electricity, but the remaining power is concentrated, and the more it is used, the less it will be, until it is exhausted.

Chemical reactions always take time. If the local substance is consumed too much and the concentration is too low, the reaction will not proceed further. After leaving it for a period of time, the concentration becomes higher when the substances inside the battery are homogeneous. There will be electricity.

Virtual electricity. Can be used up. Go and charge it again. This is normal. It's okay. I have four pieces of electricity, and sometimes I don't use one of them for a long time, and I don't charge it, but when I use it again, there will still be a small amount of electricity.

It's virtual electricity, and it won't be there for a while.

Aren't you feeling energetic again after you sleep?

There was a little electricity, but it didn't take long.

At the same time, after a long period of storage, self-discharge will cause impurities to be deposited on the surface of the electrode, and the electrolyte will deteriorate, resulting in low open-circuit voltage and shorter continuous and stable discharge time, and eventually the battery will have no power.

At the same time, there are trace amounts of impurity elements in the positive and negative electrode materials of the battery, so that many microbatteries are formed inside, and chemical reactions are occurring all the time, consuming the active substances inside the battery, that is, self-discharge. In a place with higher temperatures, self-discharge will be faster. In addition, the amount of electricity is inversely proportional to the storage time, and the battery that exceeds the shelf life will have the problems of weak power and unstable discharge.

The shelf life of batteries of different brands, models and materials is different, so when you buy batteries, you must buy better quality, so that you can avoid no electricity after a period of use and reduce the occurrence of frequent battery replacement.

The battery is a consumable, that is, if you don't buy it, put it in the mall, its power will still be lost. If you have already bought it and dismantled the package, then do not let the poles of the battery contact with the material that can conduct electricity when not in use, so that the battery can be stored for a long time.

The battery will automatically discharge after being left for a long time. If you want to solve this problem, the best way is to store it in a plastic battery box instead of putting it in the charger after it is fully charged. Of course, after a long time, it will also discharge.

Here's how it works. In the case of a zinc-manganese battery, a redox reaction occurs inside the battery, and the negative electrode substance (zinc) is oxidized and loses electrons.

Electrons flow to the positive electrode through an external circuit, and react with manganese dioxide on the surface of the positive electrode (graphite) to reduce manganese dioxide, a process that continues so that current is continuously generated, while the negative electrode (zinc) and electrolyte solution (ammonium chloride and manganese dioxide) are constantly consumed.

If the battery is not suitable for a long time, the battery life will be shortened and the battery will not be stored. When the battery is not in use, remove it to replenish the electrolyte, charge it sufficiently, and then recharge it every two or three months.

Because after the battery is put on for a period of time, it will run away by itself, which is why Nanfu is so good, because it gathers energy ring.

The energy is released in one minute, and the same is true for batteries.

Whistleblowing is a result of the polarization effect of the battery. During the use of the battery, the charged and blindly dismantled ions will move to the positive and negative electrodes and gather there, generating a certain resistance that affects the discharge of the battery. At this time, from the outside, it looks like the battery is dead, and the discharge capacity has decreased.

But if it is left for a while, it will spread out again due to the Brownian motion of the particle. So the battery seems to be charged again.

In fact, this is also the case when charging, when charging, the positive and negative poles will more or less produce some bubbles and impurities. This makes the rechargeable grinder need to use a higher voltage to charge the battery, so the voltage of the battery increases. The general charger detects this increased voltage to determine whether it is full.

And at this time, if you move the battery to the charger for a while, you will find that it can be charged again. At this time, it is often easy to cause the battery to overcharge and return to the battery. Therefore, it makes no sense for some people to charge the battery with a travel charger, and to use the dock charge to detect whether the battery is full after charging.

To put it simply: the chemicals in the battery have not been completely reacted, and the reaction speed cannot keep up with the power consumption when the electricity is about to run out, which is manifested as running out of power, and there will be a little electricity if he is fully reacted for a short period of time.

The battery will run out of power after a long time, so it is recommended to use the battery every once in a while to avoid aging and prevent the battery from running out of power.

A battery is a device that converts dry chemical energy into electrical energy in a cup, trough or other container or composite container that contains an electrolyte solution and metal electrodes to generate electric current. It has a positive electrode and a negative electrode. With the advancement of technology, batteries generally refer to small devices that can generate electrical energy.

Such as solar cells. The performance parameters of the battery mainly include electromotive force, capacity, specific energy and resistance.

Here's how it works inside the battery: First of all.

Take carbonic acid batteries, for example.

The redox reactions that occur inside are: Zn(s) Zn2+(AQ) +2E- 2Mno2(S) +NH4+(AQ) +2E- MN2O3(S) +2NH3(AQ) +H2O(L) when the battery is in use.

The above reactions will occur over and over again. However.

If you use it all the time, the concentration of chemicals in the battery will continue to decrease.

Until the concentration of those chemicals drops to a certain low level.

The rate of reaction is not sufficient for the battery to generate sufficient electromotive force (as the rate of reaction decreases as the concentration of the chemical decreases).

At this time, the battery is announced"There is no electricity for the time being".But when the battery is left out for a while.

Based on the fact that there is also a certain rate of chemical reaction at room temperature.

So in the elapsed time.

There will be a slight increase in the concentration of chemicals in the battery.

At this time, it is equipped with a mausoleum"Savings"A little bit of power.

So you can use it for a little longer. Of course.

At this time, the battery only blooms its afterglow.

It won't be long anymore.

Reference: My Chemical Knowledge battery discharge is based on a flat parabolic pattern, i.e., more discharge at the head and less discharge at the end. On the contrary, power-consuming appliances consume less electricity in the initial stage, and the electricity consumption is fixed only when the working temperature is reached.

Overlap the two graphs, when the power consumption exceeds the discharge, it means that there is no electricity and stop, and then turn on after the power consuming appliance cools down, because the power consumption is now lower than the discharge chart, so the appliance can be started again until it exceeds the discharge chart.

The term is called "self-discharge", one is that the moist gas in the air forms a loop between the positive and negative electrodes of the battery, and the other is the internal resistance consumption of the electrodes inside the battery.

This is because of "self-discharge".

The main cause of self-discharge is an irreversible reaction that occurs inside the battery, resulting in a loss of battery capacity. There are various types of irreversible reactions, including:

The cathode reacts irreversibly with the electrolyte.

The negative electrode reacts irreversibly with the electrolyte.

An irreversible reaction caused by impurities carried by the electrolyte itself.

Irreversible reactions caused by micro-short circuits caused by impurities generated during manufacturing.

It's up to you to put what you put together. If it's metal, then you definitely don't have it!

The battery is left unused

It won't run out of power, du is fully charged

Put the battery, you can protect the battery, not to return.

Yu was damaged. How to save the mobile phone answering battery:

1. If the mobile phone battery is left for too long and is not used, it is best to go to the mobile phone maintenance department to apply for an activation treatment for the battery, or you can use a DC constant voltage by yourself, adjust the voltage to 5 6V, and the current is 500 600mA to connect the battery in reverse. Note that you can let go with one touch, repeat up to three times, and then use the original charger for "adjustment period" charging.

2. Do not expose the battery to high temperature or severe cold, like dog days, do not put the mobile phone under the sun and withstand the scorching sun; Or take it to an air-conditioned room and put it in a place where the air conditioner blows directly. When charging, the current product is reflowed and it is normal for the battery to heat up a little.

If it is a lithium battery, it is best to charge it in three months. If it is an ordinary No. 5 battery, buy a new one before the test.
