What are the repair principles of 18650 lithium battery? What are its advantages?

18650 lithium battery repair principle 18650 lithium battery repair method one principle: the metal surface of the lithium battery that has been used for a long time will be oxidized to a certain extent, resulting in poor contact between the mobile phone battery and the mobile phone, and the use of the lithium battery becomes shorter, so use a rubber sassafras Or other cleaning tools can erase the rusty material on the surface, so that the battery and the mobile phone contact better. The principle of 18650 lithium battery repair method two: low temperature can change the electrolyte inside the lithium battery, and promote the chemical reaction of the battery that has just been frozen. The use process of a lithium battery 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 is becoming less and less useful is because the kinetic energy inside the electron is relatively large at normal room temperature, so the battery is in an active state and leakage is relatively frequent. The principle of the third method of lithium battery repair: deep discharge of the mobile phone is to achieve a deeper recharge by depleting the internal electric energy, which requires some unconventional methods. Think of a way to connect the phone to a small 1.5V light bulb, and the power inside the lithium battery will be transferred to the light bulb until all is discharged. The mobile phone slowly runs out of power through a lower voltage. Under normal circumstances, if the mobile phone is connected to the rated voltage of less than 3.6 volts, it will automatically shut down. After the battery is discharged, the recharged mobile phone battery can be used for a longer time. Advantages of 18650 lithium battery 1. Large capacity. The capacity of 18650 lithium battery is generally between 1200mah~3600mah, while the general battery capacity is only about 800mah. If combined into a 18650 lithium battery pack, the 18650 lithium battery pack is anything you want. It can break through 5000mah. 2. Long life, 18650 lithium battery has a long life, and the cycle life can reach more than 500 times in normal use, which is more than twice that of ordinary batteries. 3. High safety performance, 18650 lithium battery has high safety performance, non-explosive, non-combustible; non-toxic, non-polluting, and has passed RoHS trademark certification; all kinds of safety performance can be achieved in one go, and the number of cycles is more than 500; high temperature resistance performance, 65 degrees conditions The discharge efficiency reaches 100%. In order to prevent the battery short-circuit phenomenon, the positive and negative electrodes of the 18650 lithium battery are separated. Therefore, the short-circuit phenomenon may have been reduced to the extreme. A protection board can be installed to prevent overcharge and overdischarge of the battery, which can also extend the life of the battery.
