I believe that some friends may encounter such a problem. The battery of the mobile phone that I have used for two years suddenly swelled, and I even pried off the back case. This makes people very worried about its potential safety hazards. We must know that there will always be accidents of charging and fire happening around us from time to time. Today, the editor will give you a specific introduction to some knowledge about mobile phone drums, and hope that it can provide some help for everyone to use mobile phones healthily!
1. The reason for the cell phone battery bulge
1. Use a non-original inferior charger
If low-quality plates, refurbished or inferior components are used, heat generation and inaccurate parameter drift will cause the charging limit voltage to be out of control, causing the gas inside the battery to be squeezed, causing the battery shell to deform, fill, burst, or even explode.
2. The battery is overcharged
There is a small circuit board in the battery, which mainly protects the battery core. When it is over-current or over-charged, it will automatically disconnect and stop charging or discharging. In order to increase the battery capacity, some unscrupulous manufacturers set the limit voltage of the battery a little higher, which will cause the battery to be overcharged, because most of the chargers do not have overcharge protection, and rely entirely on the internal circuit of the battery for protection. Possibility of battery packs.
3. Charging in high temperature environment
Generally, the best environment for mobile phone charging is around 25 degrees, especially for charging in summer, when the weather temperature is high, and the heat generated by the charger, double-sided pinching will cause the temperature of the narrow surface inside the battery to rise, slow heat dissipation, and scald the battery surface protection Shell, the heat continues to intensify, making the battery bulge.
4. The quality of the battery itself
The quality problem of the battery itself is also a fatal factor causing bulging. As we all know, the key part of the battery is the battery cell. Some manufacturers use inferior batteries in order to save costs and attract the market. Generally speaking, the quality of lithium polymer batteries is more guaranteed.
5. Long-term high current charging and discharging
Fast charging is actually charging with high current. Its charging current is 6-10 times higher than that of ordinary chargers. High current charging has a certain impact on battery life. It seriously exceeds the charging load of the battery and will damage the internal structure of the battery.
Often used in a high-current charging environment, the large internal resistance of the battery consumes a lot of current and generates heat, which will cause the battery to lose water, accelerate battery aging, warp and deform the plate, increase the concentration of acid, and swell due to water loss after a long time.
2. Measures to avoid mobile phone bulging
Premise If the battery of your mobile phone has bulged, it is recommended to replace it with a new battery in time.
1. Usually, don’t play with your mobile phone while charging
We usually charge when playing games or watching TV, which will cause great damage to the battery and radiation to people. Try to avoid the habit of charging while playing with your mobile phone.
2. Use the original charger to charge the phone
When charging normally, it is recommended to choose the original charger. For example, the rated charging voltage of the battery is 3.7v, and the limit voltage is 4.2V. Try not to choose a charger that exceeds this voltage. It is best to maintain a constant current.
3. Replace the battery and select the original battery
It is recommended to only choose the original battery for the mobile phone battery. If the battery is broken, it is recommended to buy the battery from the original factory, so that the mobile phone can be used with the most peace of mind.
4. Avoid charging the mobile phone in a high temperature environment
Avoid charging the mobile phone in a high temperature environment, which will affect the life of the mobile phone battery.
3. Summary
We still need to pay attention to the problem of mobile phone battery bulging, which requires us to maintain good habits in the process of daily use of mobile phones, not charging, not charging in high temperature environments, keeping less falling, using regular batteries and charging Appliance products and other good habits.
