Analysis of 18650 lithium battery repair principle and repair method

18650 lithium battery repair principle 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. 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 significantly, resulting in temporary inactivity inside the battery and reduced leakage current. So after recharging, the standby time of the phone will increase. The 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. 18650 lithium battery repair method 1. Remove all your batteries after they are used up, and treat them with temperature. The battery will greatly shorten the use time when the temperature is unstable, because the battery is not charged and a considerable part of the lithium ion has been taken. If you have a memory battery, you can use this method to release a part of the memory battery. When winter comes, put it outside for a while, and then go 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 fully 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. Repeat a few times. It is absolutely effective. 3. In order to fully activate the 18650 lithium battery, it must be fully charged and discharged several times. The discharge circuit is composed of resistors and light-emitting diodes, and the state of discharge can be estimated through the light-emitting diodes. Battery repair refers to the general term for repairing rechargeable batteries that have deteriorated or failed through physical or chemical means. Repairing can restore the battery capacity, prolong the service life of the 18650 lithium battery, and improve the performance of the battery.
