1. Li-ion battery repair method

Use rubber sassafras or other cleaning tools can erase the rusty material on the surface.

Lithium battery repair method principle.

The metal surface of the lithium battery used for a long time will have a certain degree of oxidation, resulting in poor contact between the mobile phone battery and the mobile phone, lithium battery use time becomes shorter, and the use of sassafras or other cleaning tools can erase the surface of the rusty material, so that the battery and mobile phone contact becomes better.

Take down your battery after all the use, with the temperature treatment, the battery in the case of temperature instability will greatly shorten the use of time, because the battery is no electricity and a considerable part of the lithium ion has been with memory electricity with such a method can make memory electricity release part of the winter, put outside for a while, and then get the house.

Lithium battery repair method principle.

The low temperature can make the electrolyte inside the lithium battery change and promote the chemical reaction of the battery that has just been frozen. The process of using lithium batteries is actually a charging and discharging process. During this time, the negative and positive charges within the battery collide with each other. The reason why batteries become less and less durable is that at normal room temperature, the kinetic energy within the electrons is relatively high and thus the battery is in an active state and leaks are relatively frequent. When a lithium battery is placed in a cold environment, the microstructure of the lithium film on the surface of the lithium battery and the electrolyte, as well as their interfacing interface, change significantly, resulting in a temporary inactivity inside the battery and a reduction in leakage current. So after charging again, the standby time of the phone will increase.

There is another method, remove the battery, put about a week, will slowly consume the electricity, you need to use the machine first after the electricity is completely consumed. Then charge it all again, estimating that your current charging time must be very short, charge it all, disconnect and charge it again, repeat several times, absolutely effective.

Lithium battery repair method principle.

The cycle life of lithium batteries is about 600 times. If charged more times, the thermal movement of the molecules will cause the internal molecular arrangement of the microstructure to be gradually destroyed, and the efficiency of the stored charge will gradually decrease. The process of freezing tends to destroy the original internal structure of the battery, which may increase the ability to charge a charge for a short period of time, but may not be effective for long-term use. Once the microstructure within a lithium battery has been destroyed, it is impossible to fully restore it again, and long-term use of this method will accelerate the wear and tear of the phone's battery.

Deep discharging the phone is a way to achieve a deeper recharge by depleting the internal electrical energy, which requires some unconventional methods. Find a way to connect the phone to a small 1.5V bulb. The internal charge of the Li-ion battery will be transferred to the small bulb until it is all discharged. The phone needs to be slowly drained of power by the lower voltage. Under normal circumstances, the phone will automatically switch off if it falls below the rated voltage of 3.6 volts when it is switched on. After discharging, a recharged phone battery will last longer.
