What should I do to prevent the battery from bulging ?

How to prevent the battery bulging of electric vehicles, learn these points to extend the life of the battery for two years.

Recently, some **iPhone mobile phones have burst the shell due to battery expansion. In this regard, Bi Hui, an associate researcher at the Shanghai Institute of Ceramics of the Chinese Academy of Sciences, said: "The expansion of the battery is mainly due to the production of gas, and one of the reasons for the production of gas is the 'side reaction' inside the battery.

Side reaction' means that when there is some water or other impurities in the battery, a certain reaction may occur inside, producing oxygen, hydrogen, carbon dioxide and other gases, squeezing the battery shell, causing the battery to bulge. In addition, if the battery is overheated, it can also cause thermal stability to deteriorate, and the electrolyte inside will decompose, resulting in gas and expansion.

At present, the "bulging" battery cannot be repaired, how to prevent it? 1.Use a properly matched charger.

First of all, the protection circuit system of the irregular charger is likely to be imperfect, and secondly, the use of a charger higher than the rated voltage of the battery, such as the charger of the tablet product, the charging current will be relatively large, which will cause damage to the battery for a long time, resulting in expansion; 2.Don't wait until the battery runs out of power before recharging. If it is full, it must be taken down as soon as possible, and it is best to control the power at 20% to 80%; 3.

Buy a mobile phone battery from a regular manufacturer. Some unqualified non-original cheap batteries often cut corners and imperfect protection circuits; 4.Don't charge your phone while you're using it.

Charging while playing will make the phone too current, and it will be in a higher temperature environment for a long time. High temperatures can cause side reactions in the electrolyte to produce gases.

It's best not to use it anymore, the bulge is a problem of individual differences in the battery, not a problem with the Scud charger, I have two batteries of BL-4C and BL-5L with the original wire charger, and it is also bulging, no way, only to buy a new battery, otherwise it is easy to lead to ** and other dangers, which cannot be repaired. For the safety of you and the people of Jiasen Stove, it is recommended to purchase a new battery.

Hope it helps!!

When the phone is bulging, do not continue to use it! Take it to the after-sales center repair point and let the professionals check the repair.

If the mobile phone battery is bulging, it is likely that a chemical reaction occurred instantaneously, resulting in the production of carbon dioxide, carbon monoxide, hydrogen and other gases. Because the battery is very tightly sealed, the gas cannot flow out, and a bag will bulge inside. However, after the mobile phone bulges, it means that the inside of the mobile phone battery cell has changed.

Reasons for the bulging of the phone:

1. Using a non-original inferior charger for charging, the voltage and current that are compatible with the charging requirements of the mobile phone cannot be provided during the charging process, resulting in overcharging, which often causes the tolerance of the mobile phone battery to decline and age in advance;

2. Poor charging or use environment, abnormal use habits, choose to continue to use without charging under low power conditions, or charging in extreme environments. If you like to put your mobile phone under the windshield to charge when driving, in hot weather such as summer, the mobile phone will receive direct sunlight for a long time, resulting in too high temperature of the fuselage, resulting in abnormal battery reaction, and bulging may occur during charging;

3. The problem of the mobile phone battery itself. Of course, the probability of bulging caused by battery quality problems is very low. In the production process, due to process problems or poor quality inspection, problematic batteries enter the market.

Usually this kind of mobile phone will have a phenomenon such as a bulging battery for a short period of time.

Lithium battery bulging solution.

Solution: 1, do not continue to use the toner cartridge battery, there is a toner cartridge pack, back to 2, usually do not play when charging the phone. Stick the battery regularly to avoid dangerous situations.

3. Generally, when charging, pay attention to the choice and size of the charger, the rated charging voltage of the battery is 3 7V, the limit voltage is 4 2V, try not to choose the charger that exceeds the voltage, you can keep the constant current as the best.

1.If the phone battery bai

It has been inflated and puffed up

If you come, there is also a way to solve it. It is.

Use your finger to find the battery DAO first

The void is specialized, and the target will poke a small hole and let the air inside run out.

2.In addition, buy a new lithium battery pack and purchase a new battery to replace it.

3. When the lithium battery pack 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.

The battery is swollen, which means that the battery has been scrapped. I'm afraid of charging again. Under normal circumstances, the battery is no longer used. Should**. Well, there are people who collect batteries. Whoever stuffs those scraps, they'll be **.

If it is a hot bulge, put the battery in a cool place to lower the temperature, if the battery service life is up, directly dispose of it as hazardous garbage.

In the forum, many people who signed up after me have become ** members.

The battery bulge should be removed and placed in a special institution for collecting waste batteries, not thrown into the trash, it is harmful to the environment.

I can only buy new ones. The warranty period is already out. And the battery also has a life. It's time for a new one.

For battery bulging treatment, please refer to the test answer.

The mobile phone battery is the life of the mobile phone, it almost determines the life of the mobile phone, and now the mobile phone battery is basically a lithium battery, and this kind of battery will bulge and swell when it is used. So how do you prevent your phone battery from bulging?

1. It is normal for the mobile phone to generate no more than 60 at normal room temperature, and the battery will not be damaged.

2. The use of high-current charger should not be too long, too long charging will damage the battery, and heat will also be generated.

3. It is best to use the original or quality reputation of the charger.

4. If you are not in a hurry to use it, it is recommended to charge it with a socket charger (slow charging mode) to avoid causing the battery to heat up, and it is best to use the original charger of the mobile phone.

The above is an introduction to how to prevent mobile phone battery bulging, I hope it will help you.

1.Please do not continue to use bulging batteries. If there is a bulge, try to replace it with a new one in time.

Try not to rely on some methods taught online to continue using the battery. 2.Don't usually charge your phone while playing with it.

Check the condition of the battery regularly to avoid dangerous situations. 3.When charging, pay attention to the choice of charger.

For example, the rated charging voltage of the battery is, and the limit voltage is to try not to choose a charger that exceeds this voltage. It is best to maintain a constant current. 4.

Choose batteries produced by large manufacturers, so that the quality is relatively reliable. The main thing is that you should pay more attention to the degree of battery damage caused by your usual usage habits. 5.

If the phone battery has been charged and bulging, first use your finger to find the gap in the battery (the back of the phone battery is close to the phone charging electrode, and it is a little soft to press down). Just poke a small hole with a needle to let the air out of it.

Please do not continue to use the battery bulge and go to the service center for inspection and repair as soon as possible.

Reasons: 1. When the battery leaves the factory, there are defects in design and structure.

2. There is a filial piety and a joke on the quality of the battery.

3. There is no protective plate inside the product, positive and negative electrode pieces, and the electrolyte is unevenly distributed.

Method: 1. Please do not continue to use the bulging battery, if there is a bulging situation, try to replace the new battery in time, and try not to rely on some methods taught online to continue to use the battery.

2. Don't charge while playing with your mobile phone, and sell the battery regularly to avoid dangerous situations.

3. When charging your mobile phone, pay attention to choosing the right charger and maintaining a constant current.
