Tips to prevent mobile phone battery incidents

Tips to prevent cell phone battery failures Tips to prevent cell phone battery failures At least for now, the safety of lithium polymer batteries seems to be very high, such as ignition and blasting conditions are generally difficult to break through. However, we can also know from media reports from time to time that the battery catches fire and explodes, and people feel scared. In this regard, the Chemistry Laboratory of Nanjing University of Science and Technology conducted a practical test of battery charging safety, which must answer people's questions to a certain extent. Laboratory operators will participate in the test of two lithium battery symbols, one for normal batteries and the other for maintenance of damaged batteries. After charging for more than 12 hours, the normal battery did not show any abnormality, while the battery with damaged repair circuit appeared deflated after the temperature rose to 100 degrees. Occasionally, the mobile phone battery will explode. When the lithium battery is charged, there will be a maintenance circuit to maintain it to prevent damage to the lithium battery under overvoltage and overcurrent conditions. When the battery overflows, the maintenance system will automatically recognize it and switch from high current to low current, so that the phone cannot be charged. Therefore, if the lithium battery is not faulty in the charger and the maintenance circuit, even if it is charged overnight, it will not cause structural damage to the battery, and it will not cause the battery to catch fire and explode. According to media reports, mobile phone batteries continue to cause blasting conditions that may be due to damage to the repair circuit. It can be considered that the battery's condition is affected by external forces such as drops, or there is a high temperature and humidity environment operating experience. There are several things to pay attention to when charging mobile phones. In addition, although the safety of polymer lithium batteries is higher than that of lithium batteries, there are still several points to pay attention to in daily use. First of all, it is necessary to ensure that the original battery and charger are used. Of course, this is not a problem with the more integrated body planning products. The second is that you should not be afraid to charge your mobile phone for a long time, but you must pay attention to the environment where the mobile phone is charged. The heat dissipation must be better. For example, charging the mobile phone under the pillow may be a more dangerous behavior. Third, once the cell phone battery becomes swollen, you must stop using it immediately. You can replace the battery immediately. Do not open the battery for regular after-sales treatment. Do not continue to use it, otherwise there may be risks. From the early nickel-metal hydride batteries to today’s lithium batteries and lithium polymer batteries, the safety of mobile phone batteries has generally improved. Generally speaking, as long as it is properly maintained, it is difficult for mobile phone batteries to cause personal safety burns or explosions even if they are charged for a long time. Consumers should not worry too much. Disclaimer: Some pictures and content of articles published on this site are from the Internet. If there is any infringement, please contact to delete.
