Detailed explanation of the principle of lithium battery repair

Repair principle 1: 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 time of the lithium battery is shortened. Rust material makes the battery contact with the mobile phone better. Repair principle 2: Low temperature can change the electrolyte inside the 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 cycle life of lithium batteries is about 600 times. If the number of charging is increased, the thermal movement of the molecules will gradually destroy the internal molecular arrangement and microstructure, and the storage charge efficiency will gradually decrease. The freezing process is likely to damage the original internal structure of the battery, and it may be able to add charge in a short period of time, but long-term use may not be effective. Once the microstructure in the lithium battery is destroyed, it is impossible to fully recover. Long-term use of this method will accelerate the loss of the mobile phone battery. Repair principle 3: 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. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
