Detailed answer to the repair method of polymer lithium ion battery

Polymer lithium-ion batteries refer to batteries containing lithium in the electrochemical system. Lithium metal batteries do not contain metallic lithium and can be charged. Then we encounter lithium-ion batteries that are broken and cannot be used. , so how will the lithium battery be repaired?
Below we explain in detail the three repair methods of polymer lithium-ion batteries, you can try it to see if it is practical. Let's take a look together!
Repair method one:
Remove all the power from the polymer lithium-ion battery on the product and treat it correctly with the temperature. The battery can greatly reduce the use time when the temperature is not stable. This is because the battery is completely depleted. At the same time, there are quite a few lithium ions that already contain memory electricity. Using this method can also release part of the memory electricity. If winter comes, put it outside for a while, and then bring it into the house. The ultra-low temperature can change the electrolyte inside the lithium-ion battery, driving a chemical reaction in the battery that has just been frozen. The use of lithium-ion batteries is actually a charging and discharging process. During this time, the negative and positive charges in the battery collide with each other. The reason why the battery is becoming less and less durable is because at normal room temperature, the kinetic energy inside the electron is still relatively large, so the battery remains active, and the leakage is relatively frequent. However, when a lithium-ion battery is placed in an ultra-low temperature environment, the microscopic particle structure of the lithium film on the surface of the lithium-ion battery and the electrolyte, as well as their interface layer, will undergo significant changes, resulting in temporary inactivity inside the battery and leakage current. reduce. Therefore, after recharging, the standby time of the mobile phone will increase.
Repair method two:
Another method is to remove the battery and leave it for about seven days to gradually consume the electricity. First use the machine to fully consume the electricity. Then charge it fully again. It is estimated that the charging time must be very short now. After charging fully, disconnect and charge again, and repeat several times. The cycle life of lithium-ion batteries is about 600 times. If the charging times are too many, the thermal movement of the molecules will gradually damage the microscopic particle structure of the internal molecular arrangement, and the efficiency of storing charges will be inadvertently reduced. The freezing process is relatively easy to seriously damage the original internal structure of the battery. It may also improve the ability to charge the charge in the shortest time, but it may not be useful for long-term use. Once the microscopic particle structure in the lithium-ion battery is severely damaged, it is almost impossible to completely restore it to normal. Long-term use of this method will accelerate the natural wear and tear of the battery.
Repair method three:
Use a rubber eraser or other cleaning tools to wipe off the rusty components on the surface. The metal surface of the lithium-ion battery used for a long time will be oxidized to a certain extent, resulting in poor contact between the battery and the product, and shortening the service life of the lithium-ion battery. The rust component makes the contact between the battery and the product better.
