Experts explain why mobile phone batteries have become grenades

Mobile phone battery explosion experts explain why mobile phones turned into grenade According to the Voice of my country News evening peak report, with the popularity of smart phones, people will find their batteries more and more useless, so carrying spare batteries and mobile phone charging stations have become a Kind of habit. However, the use of mobile phone batteries is also a problem to pay attention to. If used improperly, it may even cause safety accidents. This is not a line, nor is it a joke. Fire expert Li Jin said that such things will really happen in our lives. The cell phone battery is the culprit behind the instant grenade. Li Jin: On October 24 this year, a fire broke out in a farmhouse in Guangdong Province. Later, it was discovered that the owner's mobile phone overheated, causing an explosion. The flying sparks finally burned the house. Li Jin said that mobile phones not only bring hidden dangers to mobile phone batteries, but the batteries we often use now also have hidden dangers. Li Jin: On June 23, 2013, from Metro Line 10 to Dahongmen Station, a female passenger's charging bag spontaneously ignited, causing the car to smell of burning and smoke. The passengers were also frightened in a short time and evacuated urgently. On August 24 this year, this situation happened again on Beijing Subway Line 15, which was also caused by the spontaneous combustion of the charging device in the passenger bag. How can a good-end mobile phone turn into a grenade? What caused the explosion of the mobile phone battery? Li Jin analyzed that the formation of these security incidents is still an important reason for the use of non-genuine batteries. Li Jin: This phone is designed with a protection circuit to prevent overcharging and overloading. Charging is safe under normal conditions. In addition, some external conditions can also cause a mobile phone attack to burst out instantly. Li Jin: Extreme voltage and current can cause the battery to explode. For example: more than 9 volts, may exceed 3 amperes of current, but our civilian chargers generally do not exceed such a high current or voltage. With the diversification of mobile phone functions, many people are accustomed to listening to music, playing games, watching movies, etc. Li Jin said that this kind of overuse will also cause the mobile phone battery to overload and burst. Li Jin: Long-term discharge may cause problems with long-term charging. For example: listening to music for a long time, watching a movie for a long time, the long hands will be hot or even hot at these times. There is still the habit of charging the mobile phone for one night, so the lithium battery will be added, the battery will drum, take off, the electrolyte of the battery is broken, heat and gas occur, causing the battery to swell, therefore, the surface of the battery ruptures, encounters oxygen, and the core Will be shattered. Therefore, experts suggest that the use of mobile phone batteries must not be cheap and use non-genuine batteries, and at the same time use the mobile phone batteries correctly and cherish the good habit of charging. Li Jin: Once it is found that the battery of the mobile phone is not fully charged, it may be a hot one-time charge, or an abnormal phenomenon such as the flat surface of the mobile phone, the battery should be replaced immediately to avoid catastrophe.
