Under what circumstances will the mobile phone lithium-ion battery swell

1. The quality of lithium-ion battery itself is inferior. The number of mobile phones has increased, and the batteries have become diverse. Many manufacturers produce batteries. In pursuit of profit, some fake and inferior batteries. The most important component of the battery is the battery cell. Poor quality, insufficient power, false capacity, etc. Generally good batteries have a smooth surface, and the texture is generally soft and hard. The surface of inferior batteries becomes very hard; 2. The so-called good horse with a good saddle is the reason for using non-original chargers. , No matter how good the lithium-ion battery is, if there is no good charger to charge the lithium-ion battery, it is easy to cause the bulging phenomenon of the lithium-ion battery. This is because the parameters of each charger are different, especially in terms of overcharge and overcurrent power. Long-term charging will damage the lithium-ion battery pack; 3. To prolong the life of the lithium-ion battery pack in a high-temperature environment for a long time, the ambient temperature is an important factor, which is also an important reason for the bulging of the lithium-ion battery. The high temperature environment will cause the battery heat to rise. Avoid direct sunlight, and at the same time, it is best to unplug it when the battery is fully charged. The reasons for the bulging of the battery: 1. The level of battery manufacturing, the uneven electrode coating, and the rough production process; 2. The violent reaction of the short circuit generates a lot of heat, which in turn causes the electrolyte to decompose and vaporize, and the battery bulges. 3. In addition, the phenomenon of bulging will occur if the battery is not used for a long time, because the air is conductive to a certain extent. Therefore, if the battery is left for too long, it is equivalent to the direct contact of the positive and negative electrodes of the battery, causing a chronic short circuit.
