18650 lithium battery repair method and principle analysis of lithium battery repair method

1. Remove all your 18650 lithium batteries after you have used them up, and use temperature to solve them. The battery will greatly shorten the use time when the temperature is unstable, because the battery has no electricity and a considerable part of the lithium ion already has a memory battery. In this way, a part of the memory battery can be released. Winter is here, put it outside for a while, and then inside the house. 2. There is another way to remove the battery, leave it for about a week, and slowly consume the electricity, first use the machine to completely consume the electricity. Then charge it all again. It is estimated that your current charging time must be very short. After the charge is full, disconnect it and charge it again, repeating it several times, it is absolutely effective. The principle of lithium battery repair method one: the metal surface of the 18650 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 time of the lithium battery becomes shorter. Erase the rusty material on the surface to make the battery contact with the phone better. The principle of lithium battery repair method two: low temperature can change the electrolyte inside the 18650 lithium battery, prompting 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. When a lithium battery is placed in a low-temperature environment, the microstructure of the lithium film on the surface of the lithium battery and the electrolyte, as well as their interface, will change distinctly, resulting in temporary inactivity inside the battery and reduced leakage current. So after recharging, the standby time of the phone will increase. The principle of lithium battery repair method three: deep discharge of the mobile phone is to achieve a deeper recharge by depleting the internal power, which requires some unconventional methods. Think of a way to connect the mobile phone to a small 1.5V light bulb, and the power inside the 18650 lithium battery will be transferred to the light bulb until all is discharged.
