What will affect the life of mobile phone lithium battery?

Have you ever thought about the feeling of the battery? Many people find that after a few days of use, the battery of the mobile phone is charged faster and faster, but the standby time is getting shorter and shorter. In order to make the battery life of the mobile phone longer, many people go online and follow the advice on how to extend the battery life. But did you know? Many online charging methods are wrong, and you have been cheated for years. Do you want to completely drain the battery before charging? No way! Deep discharge will damage the battery. It is said that the battery has a memory function. You must wait for the mobile phone battery to be fully discharged before charging to 100%, or the battery will remember the proportion of charging Demand, so the battery has no charging demand, and the charging will not overflow. Smart phones now use lithium batteries, and the technology and structure of lithium batteries have undergone tremendous changes. New energy power lithium-ion battery research and development engineer Wang Yonggang, Tianneng lithium battery research and development engineer, told the reporter of 'Science and Technology Daily' that the complete exhaustion of electricity, the so-called deep discharge, may have an irreversible impact on the internal material structure of the battery and shorten the battery life. When charging, the positive lithium ion jumps from the positive electrode into the electrolyte, crawls through the winding holes in the diaphragm, swims to the negative electrode, and merges with the electrons from the positive electrode earlier; the discharge is reversed. Dr. Hua Zhang graduated from the University of California, Los Angeles, the head of the Department of Materials Science and Engineering. In the United States, he made an example: whether it is discharging or charging, lithium ions must escape their original structure, a bit like holding a bunch of things from a room to another. Therefore, the knowledge of battery life should be based on the knowledge of battery structure. In other words, during the charging and discharging process, the fewer lithium ions participate in movement each time, the less damage to the structure; the slower the speed of each movement of lithium ions, the less damage to the structure. If the lithium ions are exhausted, there will be a deep discharge. If the lithium ions continue to be extracted, this is harmful to the battery. Do you want to charge it right away? Don't! The battery has overcharge protection. When the phone is charged, the battery will be fully charged immediately after it is charged to 100%, otherwise it will damage the battery life. In this regard, Wang Yonggang said that there is no need to worry too much. Lithium batteries are usually equipped with overload protection. When the battery is full soon, it will automatically switch to charging, that is to say, the charge is very slow, and it is still very small. When the power supply will automatically cut off and overflow, it will not continue to overcharge, so The rush to 100% will not have a major impact. Wang said that many people like to charge their mobile phones before going to bed. Driving the mobile phone at night will also cause battery loss, and the charger will continue to charge the mobile phone with a small amount of current. But such a long cycle will have an impact on battery life. Will scattered charging damage the battery? Wrong! Light charging and discharging are good for the battery. The typical life of a lithium battery is hundreds of charge and discharge cycles. The charge-discharge cycle here refers to the process of recharging the battery after it is used up, not the process of plugging the battery into the charger and taking it out again. Wang said that shallow charging of lithium batteries or charging at odd times will have little effect on the structure of the positive and negative materials, and will not affect the life of the battery. Therefore, we usually emphasize that the charging and discharging of lithium batteries should be light and light, and do not challenge the limits of batteries. Zhang Hua said. Linking to these practices will also affect battery life. Charge with non-original chargers. Different models of mobile phones have their own chargers. When using non-original chargers, the charger current may be too large and irreversibly affect battery performance. attack.
