Explanation on the repair method of 18650 lithium battery

Repair method of 18650 lithium battery 1. Repair method of lithium battery 1: Use an eraser or other cleaning agent to wipe off the rust on the surface. Lithium battery calibration method 1. Principle: Long-term use of lithium batteries will have a certain degree of oxidation in the metal appearance, resulting in poor contact between the mobile phone battery and the mobile phone, the lithium battery has a short use time, and the rust material can be wiped off with rubber or other cleaning materials. The appearance allows a better battery and cell phone connection. 2.Lithium battery correction method 2: After using your battery, the temperature and battery temperature will be greatly reduced, because the battery has no electricity and quite a lot of lithium ions in the memory can be used in this way. Part of the electric version is coming in winter, and there is a period of time outside the house. Lithium battery calibration method principle 2: low temperature will cause changes in the internal electrolyte of the lithium battery and promote the chemical reaction of the freshly frozen battery. The application process of lithium batteries is actually a charge and discharge process. During this period, the negative and positive charges in the battery collide with each other. The reason why the battery will be less and less used is that the kinetic energy inside the electronics is relatively large at normal room temperature, so the battery is in an active state and leaks more frequently. When a lithium battery is placed in a low-temperature environment, the microstructure of the lithium membrane and electrolyte on the exterior of the lithium battery and its interface will change significantly, causing the battery to be temporarily inactive and reducing leakage current. Therefore, after charging, the battery time of the phone will increase. 3. Lithium battery correction method 3: There is another way, remove the battery and leave it for about a week, the power will gradually be consumed, and the machine must be used to complete the power consumption. Then fully charge, it is estimated that your current charging time must be very short, after fully charged, disconnect and charge, repeat several times, it is absolutely effective. Three Principles of Lithium Battery Calibration Method The cycle life of lithium batteries is about 600 times. If charged repeatedly, the thermal movement of the molecules will gradually destroy the internal molecular microstructure, and the storage efficiency of the charge will gradually decrease. The freezing process will only destroy the original internal structure of the battery, which may increase the ability of the battery to charge in a short period of time, but it may not be effective in the long run. It is impossible to completely recover the microstructure damage of lithium batteries, and long-term use of this method will accelerate the wear and tear of mobile phone batteries. The three principles of lithium battery calibration methods: the mobile phone is deeply discharged, that is, through the exhaustion of internal electricity, to achieve a deeper level of charging, which requires some unconventional methods. Find a way to connect the phone to a 1.5v light bulb, and the energy in the lithium battery will be transferred to the light bulb until all the light is emitted. Under low voltage, the battery of the mobile phone is insufficient. Under normal circumstances, if it is connected to a rated voltage of 3.6 volts, the phone will automatically shut down. After discharging, the charged mobile phone battery can last longer. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
