What are the methods for repairing lithium ion batteries?

　　(1) Use rubber sassafras or other cleaning tools to remove rust on the surface. The principle of lithium ion battery repair method: the metal surface of the long-term lithium ion battery will be oxidized to a certain extent, resulting in poor contact between the mobile phone battery and the mobile phone. The service life of the lithium-ion battery is shorter, and the rust on the surface can be removed with a rubber eraser or other cleaning tools, so that the battery can better contact the mobile phone

　　(2) After the battery is used up, remove all batteries for temperature treatment. When the temperature is unstable, the battery will greatly shorten the service time, because the battery has no power, and a considerable part of lithium ions have memory power. This method can release some memory current. Winter comes, put it outside for a while, and then take it to the house. The principle of lithium ion battery repair method 2: Low temperature will change the electrolyte in the lithium ion battery and promote the chemical reaction of the newly frozen battery. The use process of lithium ion battery is actually a charging and discharging process. During this period, the positive and negative charges in the battery collide with each other. The reason why batteries become more and more useless is that, at normal room temperature, the kinetic energy inside the electron is relatively large, so the battery is in an active state and leaks relatively frequently. When the lithium-ion battery is placed in a low temperature environment, the microstructure of the lithium film and electrolyte on the surface and interface of the lithium-ion battery will change significantly, resulting in temporary inactivity of the battery and reduced leakage current. Therefore, the standby time of the phone will increase after charging

　　(3) There is another way. Take out the battery, leave it for about a week, and slowly consume the power. First of all, using the machine completely consumes electricity. Then rinse it all off. It is estimated that your current charging time must be very short. When full, disconnect and flush again. Repeat several times. This is absolutely effective. 3 Principle of lithium ion battery repair method The cycle life of lithium ion battery is about 600 times. When the number of charges is large, the thermal movement of molecules will gradually destroy the microstructure of the internal molecular arrangement, and the charge storage efficiency will gradually decrease. The original internal structure of the battery is easy to be damaged during the freezing process. It may increase the charging capacity in a short time, but it may not be effective for long-term use. Once the microstructure of lithium ion battery is damaged, it is impossible to completely recover. Long term use of this method will accelerate cell phone battery loss. The principle is that the deep discharge of the mobile phone is achieved by exhausting the internal electric energy, which requires some unconventional methods. Find a way to connect the mobile phone with a 1.5V small bulb. The power inside the lithium-ion battery will be transferred to the small bulb until it is all lit. The phone will slowly run out of power through low voltage. Under normal circumstances, if the connection is lower than the rated voltage of 3.6 V, the phone will automatically shut down. The mobile phone battery will discharge longer after charging.
