What are the methods for repairing lithium-ion batteries?

1. Use rubber sassafras or other cleaning tools to remove the rusty material on the surface. The principle of the lithium ion battery repair method: the metal surface of the lithium ion battery used for a long time will be oxidized to a certain degree, resulting in poor contact between the mobile phone battery and the mobile phone. The use time of the lithium ion battery is shortened, and the rusty material on the surface can be wiped off with a rubber eraser or other cleaning tools, so that the battery is in better contact with the mobile phone

2. After the battery is used up, remove all the batteries and perform temperature treatment. When the temperature is unstable, the battery will greatly shorten the use time, because the battery has no electricity, and a considerable part of the lithium ion already has a memory battery, this method can release some The memory current, winter is coming, put it outside for a while, and then bring 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 battery that has just been frozen. Lithium The use process of ion batteries is actually a charge and discharge process. During this period, the positive and negative charges in the battery collide, and the reason why the battery becomes more and more useless is that at normal room temperature, the internal functions of the electrons are relatively large. Therefore, the battery is in an activated 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 of the lithium-ion battery and its interface will change significantly, causing the battery to be temporarily inactive and leaking The current decreases, so after charging, the standby time of the phone will increase.

3. There is another way to remove the battery, leave it for about a week, and slowly consume the power. First, use the machine to completely consume the power, and then rinse it all away. It is estimated that your current charging time must be very short. After filling, disconnect and rinse again. Repeat several times. This is absolutely effective. Lithium-ion battery repair method 3 principle The cycle life of lithium-ion batteries is about 600 times. When the number of charges is large, the thermal movement of the molecules will gradually destroy the microstructure of the internal molecular arrangement, and the charge storage efficiency will gradually decrease. The freezing process easily destroys the original internal structure of the battery. It may increase the charging capacity in a short time, but long-term use may be ineffective. Once the microstructure of a lithium-ion battery is damaged, it cannot be completely restored. Long-term use of this method will accelerate the loss of mobile phone batteries. The principle is: the deep discharge of the mobile phone is to achieve deep charging by depleting the internal electric energy, which requires some unconventional methods. Find a way to connect the phone with a small 1.5V light bulb, the power inside the lithium-ion battery will be transmitted to the light bulb until it is all lit. The phone will slowly drain its power through a lower voltage. Under normal circumstances, if the connected voltage is lower than the rated voltage of 3.6 volts, the phone will automatically shut down. The battery of the mobile phone after charging takes longer to discharge.
