What is the principle of aging lithium batteries, which can be restored when put in the refrigerator

How to bring your phone battery back to life.

When your action** battery life becomes shorter (memory effect or aging), do you buy another battery to replace it?

The next time you find yourself in this situation, save your money and tell you a very effective way to try it

1.Wrap the battery in newspaper and put it in a plastic bag, wrap it in the freezer for three days (the newspaper can absorb excess water).

2.After three days, take it out and put it at room temperature for two days.

3.After two days, the battery will be charged, and after it is fully charged, it will be loaded for an action ** wrap test (estimated to save 80%-90%)

This message was revealed by an engineer from a well-known battery manufacturer, and according to friends who have tested it, the effect is quite effective.

This is not a safe method, each thing has its own service life, and it will be eliminated after a long time! That is, the principle of thermal expansion and cold contraction in physics, which is not safe!

Nonsense, how is it possible, you are unscientific, just because of the thermal expansion and contraction, the power is only a little bit, and it won't take a while.

That's true, presumably because the low temperature environment can activate aging chemicals

Another way is to put the battery on the concrete floor and grind it non-stop.

Both sides are ground for a long time.

Of course, it will be very hot when grinding, but the battery power will rise a little after grinding. Can be used for a while. You can continue when you run out of power. However, it will take less time if you continue.

It's really useless to use it like this a few times.

OK.

Lithium batteries use non-aqueous electrolyte systems, and lithium-embedded carbon materials are thermodynamically unstable in non-aqueous electrolyte systems. In the process of first charging and discharging, due to the reduction of the electrolyte, a solid electrolyte intermediate phase (SEI) film will be formed on the surface of the carbon anode, which allows lithium ions to pass through but does not allow electrons to pass through, and makes the electrode electrode active materials with different charged states in a relatively stable state, so it has a low self-discharge rate.

Pool considerations.

Lithium-ion batteries can be stored in a clean, dry and ventilated room with an ambient temperature of -5°C-35°C and a relative humidity of no more than 75%. The battery level remains between 30% and 50% of the nominal capacity. It is recommended to recharge stored batteries every 6 months.

End-of-discharge voltage: The end-of-discharge voltage of the battery should not be less than: the number of cells in series). Over-discharge of the battery will shorten the battery life, and in severe cases, it will lead to battery failure.

Yes, here's how:

1. Wrap the battery in newspaper and then put it in a plastic bag, wrap it in a freezer for three days (newspaper can absorb excess water).

2. After three days, take it out and put it at room temperature for two days.

3. Charge the battery after two days, and install it for dynamic wrapping test after being fully charged (estimated to save 80%-90%)

Someone once said on the Internet that aging lithium batteries will return to normal if they are frozen in the refrigerator. I've also tried freezing the battery in the fridge for a few hours, but nothing worked.

The test was effective and saved a laptop battery. Freeze for as long as possible, and take it out for at least a day before charging. Wrap in plastic wrap and put it in the freezer compartment of the refrigerator.

My laptop battery starved to death, only 8% charged, could not be charged, discharged to 0%, fridge frozen for 10 hours, taken out and left for 1 hour.

Miraculously resurrected, can be recharged.

You don't have to leave it in the refrigerator for 3 days. A few hours will do.

It is best not to do this, according to the construction principle of lithium battery, the energy conversion of lithium battery at low temperature will be greatly reduced, if it is only used, it is best to place it in a cool and dry place.

The principle of putting the lithium battery of the mobile phone in the refrigerator is as follows:

Low temperature can change the electrolyte inside the mobile phone battery, promoting the chemical reaction of the battery that has just been frozen; The use process of mobile phone battery belongs to the charging and discharging process, the negative charge and yang charge in the battery collide with each other, at normal room temperature, the kinetic energy inside the electron is relatively large, the battery is in an active state, and the leakage situation is relatively frequent, and the battery is put into a low-temperature environment, the microstructure of the buried lithium film and the electrolyte on the surface of the lithium battery, as well as the interface will change significantly, resulting in the temporary inactivity of the battery, the leakage current is reduced, and after charging again, the hidden rot waiting time of the mobile phone will increase; The freezing process can easily destroy the original internal structure of the battery, which may increase the ability to charge the battery in a short time. Note: Long-term use of this method may not be effective.

Low temperature can change the electrolyte inside the mobile phone battery, promoting the chemical reaction of the battery that has just been frozen; Professor Ye Gaoxiang of the Department of Physics of Zhejiang University said.

Professor Ye introduced that the use process of mobile phone batteries is actually a charging and discharging process. During this time, the yin and yang charges within the battery collide with each other. The reason why the battery will become less and less used is that at normal room temperature, the kinetic energy inside the electrons is relatively large, so the battery is in an active state, and the leakage is relatively frequent.

When the battery is placed in a low-temperature environment, the microstructure of the lithium film and the electrolyte on the surface of the lithium battery, as well as their interface, will change significantly, resulting in temporary inactivity inside the battery and a reduction in leakage current. So after charging again, the standby time of the phone will increase.

At present, lithium batteries are commonly used for mobile phone batteries, and theoretically speaking, a lithium battery can be charged about 6,000 times. If the number of charges is too high, the thermal movement of the molecules will gradually destroy the microstructure of the internal molecular arrangement, and the efficiency of storing the charge will gradually decrease.

The freezing process is easy to destroy the original internal structure of the battery, which may increase the ability to charge in a short period of time, but it may not be effective for long-term use. Professor Ye said that once the microstructure in the battery is damaged, it is impossible to fully recover, and long-term use of this method will accelerate the wear and tear of the mobile phone battery.

Who told you you just put it in the fridge when it's broken? It's just that the old battery is put in the refrigerator for a few days, which can prolong the battery use time, the principle is to stimulate the vitality of lithium electronics, which can only be said to be a little useful, and the battery can only be replaced with a new one if it is scrapped.

Because low temperature can change the electrolyte inside the mobile phone battery, promoting the chemical reaction of the battery that has just been frozen.

The use of a mobile phone battery is actually a process of charging and discharging. The yin and yang charges inside the battery collide with each other. The reason why batteries are becoming less and less used is that at room temperature, the kinetic energy inside the electrons is relatively large, so the battery is in an active state, and the leakage of electricity is relatively frequent.

When the battery is in a low temperature environment, the microstructure of the lithium film and electrolyte on the surface of the battery and the interface between them will change significantly, resulting in temporary deactivation of the battery and reducing the leakage current. So after charging, the standby time of the phone will increase.

The charging and discharging of a mobile phone's lithium-ion battery is generated by the positive and negative flow of the battery's ion current. It is like a person's blood vessels, as we age, waste products are deposited and blood flow gradually becomes poor. Waste residue is generated due to constant charging and discharging, which hinders the flow of ions, reducing the charging capacity, and as a result, shorter talk times.

The mobile phone battery energy sticker contains a special ingredient extracted from natural ores, which can emit an electronic vibration wave of 3 40 microns, which is the same frequency wavelength as the lithium ion inside the lithium battery. These ions have a fluctuating effect with the electronic waves emitted from the mobile phone battery energy sticker, which significantly delays the oxidation reaction process of the battery, and strengthens the passage of current, so as to improve the charging and discharging efficiency, and prolong the standby and talk time. At the same time, the void radioactive energy emitted by it is used uninterruptedly, so that the electrons in the battery are neatly arranged, and the waste residue is decomposed, so that the ions flow unimpeded, so that the charging capacity is greatly improved.

1.Find a battery recovery device and activate it.

2.Wrap the battery in newspaper and put it in a plastic bag and put it in the refrigerator freezer for 3 days (the newspaper can absorb excess water);

After 3 days, take it out and put it at room temperature for 2 days; After 2 days, the battery will be charged, and the battery will be powered on after full charge (estimated to save 80 to 90% of the battery energy).

This information was revealed by an engineer from a well-known battery manufacturer, anyway, everyone has a refrigerator, so let's try it!

There is no scientific basis for this, and the main reason why low temperature can reduce the thermal movement of molecules and the battery does not store electricity is because of the prolonged contact reaction between the metal and the reactant, and the loss of free electrons. The main purpose of putting the battery in the refrigerator is to use the low temperature below zero in the refrigerator compartment to eliminate the memory ability of the battery, so as to increase the storage capacity of the battery, but this is not a scientific method and has no effect on the vast majority of lithium batteries.

No, lithium-ion batteries have a certain lifespan, especially if the internal production control of some batteries is not good, the internal resistance is large, and the life will be greatly reduced, you can take a look at the answers I gave to other people, and the "lithium-ion battery", "lithium battery" entry.

It cannot be restored, but sometimes the board can be activated, and it is okay to use it temporarily.

No, a time-wasting game.

No. Deceptive. If you can make batteries from there, won't you starve to death?

1.Freezing can restore the ionic properties of lithium batteries.

Room temperature is to promote the exertion of ionic properties.

2.At normal room temperature, the kinetic energy inside the electrons is relatively large, so the battery is in an active state, and the leakage is relatively frequent. When the battery is placed in a low-temperature environment, the microstructure of the lithium film and the electrolyte on the surface of the lithium battery, as well as their interface, will change significantly, resulting in the battery being temporarily inactive and restoring power in the refrigerator.

I tried it, and the effect is good, it is wrapped in newspaper, put it in the freezer for 3 days, that is, 72 hours, and then take it out, put it at room temperature for 2 days, recharge, and fill! More than 85% of the battery can be saved!

Put it back when the battery runs out!

Fake.

The claim on the Internet that it can be recovered is false, and it is caused by a misunderstanding of a standard inside the battery. The industry's low-temperature discharge requirements are that the discharge capacity of -20 degrees Celsius is more than 80% at room temperature. If so, it can be considered that the low-temperature discharge performance of this battery is passable.

However, some people misinterpret it as: "After the mobile phone battery is used up for a period of time, the battery is placed in a low temperature environment, and then taken out, the capacity of this battery can be restored to 80% 90% of the capacity when it left the factory."

1. The initial capacity of the battery cannot be restored

As the number of battery charging increases, the thermal movement of the molecules will gradually destroy the microstructure of the internal molecular arrangement, and the efficiency of storing the charge will gradually decrease. Freezing in the refrigerator will change the original internal structure of the mobile phone battery to a certain extent, which may increase the ability to charge the battery in a short time.

However, once the microstructure in the battery is damaged, it is impossible to fully restore it, and long-term use of this method will accelerate the wear and tear of the mobile phone battery. Moreover, this practice can easily lead to corrosion of the battery due to water ingress.

2. It is recommended to replace the aging battery

Therefore, when the battery ages, it can only be replaced.
