The battery bulge will not explode.
The cell phone battery is bulged, but it will not explode as long as it is not connected to the power supply and is not affected by heat sources external. However, it can ignite spontaneously during. the charging process, which poses a safety risk. The reason why the cell phone battery swells may be due to charging for too long.
The cell phone battery swelling problem may be caused by quality problems or malfunction. There are certain precautions when charging cell phone batteries. Used cell phone batteries must be disposed of properly to prevent them from posing many dangers. They must be recycled and used normally. The cell phone must be protected in various ways. The baterie should generally not be bulging. It is easy to inflate after excessive discharge and recharge, and excessive current will cause swelling. Also, if you are unlucky and come across poor quality batteries, they will bulge.
According to lithium battery industry standards, the lifespan of smartphone lithium batteries should be at least 500 times, and higher quality batteries can last 700 times. Taking an average of 600 cycles and charging with 50% of its power each day, it can be used for approximately 1,200 days.
It's been about 3 years. People don't plug in and charge when the battery is still more than 50% charged. The idea is that over time, batteries develop a kind of memory. This view is false. If the battery power reaches 80%, you can continue charging. Frequent charging will not damagebattery.
Causes of cell phone battery bulges:
1. Battery quality reasons or design defects, if a battery contains substandard parts or the design is unreasonable, then it is very easy to overcharge, overdischarge or the charging temperature is too high when charging. subsequent use, which will eventually cause the battery to swell, and in severe cases, it may explode.
2. When used in high temperature environments, the ambient temperature at which cell phone batteries operate is limited, whether high or low. If the ambient temperature is too low, the energy efficiency rate of the battery will decrease. If the ambient temperature is too high, the battery cells will be abnormally active. If there is a charging and discharging process during the period, thisit will accelerate. aging of the battery and increases the risk of battery swelling.
3. Use inferior chargers. Inferior quality chargers cannot provide stable current and voltage within the output range of mobile phones. Long-term use will keep the mobile phone battery in an overcharged state, eventually leading to battery swelling. .
Can the bulged lithium battery still be used?
It is not recommended to reuse the lithium battery once it has swollen. During the inflation process, the battery capacity is reduced. The lithium battery has shrunk and the standby time has been significantly reduced. In severe cases, the standby time will be extremely short, you may not even be able to make calls, and it will restart as soon as you make a call. At this point, the battery should generallybe replaced. For safety reasons, it is best to purchase a new battery.
When the lithium battery has a bulging problem, it is best not to continue using the problem battery. Because the battery core expands, when the expansion reaches a certain limit, it may explode, which is very dangerous. For your own safety, it is best to wait for the lithium battery to appear. If the bulge appears, replace it as soon as possible. The lithium battery is of poor quality and takes too long to charge. The recharged battery can no longer be used. Replace it with a new battery as soon as possible.
Will the bulging lithium battery explode?
It will generally not explode unless exposed to sunlight or high temperature. But it is better not to use such lithium batteries, because this battery is currently very dangerousher.
Lithium battery swelling is caused by overcharging during charging. The internal chemistry of the battery changes and gas is produced. Typically, soft polymer batteries “swell” when overcharged. are steel shell batteries, they will explode. Lithium batteries can explode if leaked or damaged. It is recommended that you no longer use the battery and replace it with a spare battery.
Lithium battery bulge repair method
1. When the battery inflates, we first seal the battery with plastic wrap, then put it in the refrigerator to cool for about half an hour. hour.
2. Remove the battery after the temperature has dropped, then peel off the wrapping paper on the surface of the battery.
3. Then use a needle to pierce a small hole on the surface of the batterylithium.
4. Press with your fingers to expel the gas present in the battery.
5. Seal the vent holes with masking tape.
