What is the root cause of the explosion of mobile phone batteries?lithium 3400mah 3.7v 18650 battery

release time:2023-09-14 Hits:     Popular:AG11 battery

  

  The root cause of mobile phone explosions is the battery, which can be divided into internal and external reasons. The internal reason refers to the poor quality of mobile phone batteries. Nowadays, most mobile phones use lithium batteries, and the storage capacity of lithium batteries is related to the activity of lithium metals. If lithium metals have good activity, the storage capacity of lithium batteries is high; The poor activity of lithium metal results in low storage capacity of lithium batteries. Some manufacturers may inappropriately increase the activity of lithium metal in order to increase the battery's storage capacity. However, the stronger the activity of lithium metal, the greater the likelihood of crystal branches and internal short circuits in the battery, and the higher the likelihood of phone explosions.

  External factors are the main cause of mobile phone explosions, directly related to mobile phone chargers. Zhou Hongzhi introduced that when charging a mobile phone, the charger will convert a household voltage of 220 volts into a working voltage of around 5 volts. This process requires the charger components to have good insulation performance, and the production process needs to comply with strict quality standards. Due to the correlation between the insulation capacity of some components and insulation materials in the charger and the power consumption of the charger, as the power consumption increases, the insulation capacity will decrease; During the charging process, if the design circuit of the charger is inherently inadequate, the quality of the components is poor, and the manufacturing process is not up to standard, its insulation is easily damaged, which can easily cause voltage breakdown and cause the phone to explode. Especially some chargers have inherent circuit design issues that pose significant safety hazards. It is recommended that people pay more attention to their quality when purchasing cheap chargers.
