Repair Principle 1: The metal surface of the lithium-ion battery for a long time will have a certain degree of oxidation, causing the mobile phone battery with the mobile phone, the lithium-ion battery is used to expire, and the surface with rubber or other cleaning tools can be removed The rusty substance allows the battery to contact the phone. Repair Principle 2: Low temperature can change the electrolyte of the electrolyte inside the lithium ion battery to promote chemical reactions that have just been crystallized. The use of lithium-ion batteries is actually a charge and discharge process.

During this time, the female charge and the positive charge in the battery collide with each other. The battery will be more increasingly not used, because in normal room temperature, the kinetic energy of the electronics is relatively large, so the battery is active, and the leakage is relatively frequent. The lithium-ion battery is placed in a low temperature environment, and the microstructure of the lithium film and the electrolyte surface of the lithium-ion battery, and the interior of their intersection, resulting in the interior of the battery, and the leakage current is reduced.

So after charging again, the phone's time-to-call time will increase. The cycle life of the lithium ion battery is about 600 times. If the number of charge is more, the thermal movement of the molecule will gradually be destroyed in the internal molecules, and the storage charge efficiency will gradually decrease.

The refrigeration process is easy to damage the original internal structure of the battery, and may have a new charge capability in a short time, but long-term use is not necessarily effective. Once the microstructure in the lithium ion battery is destroyed, it is impossible to completely recover, and this way to speed up the loss of mobile phone batteries. Repair principle 3: Deep discharge of mobile phones is to achieve deeper and reproduction by depleting internal energy, which is to adopt some unconventional approach.

If you want to connect your phone with a 1.5V light bulb, the amount of electricity inside the lithium-ion battery will be transmitted to the small bulb until all are light. The phone is slowly exhausted with a lower voltage.

Under normal circumstances, if the mobile phone is turned on less than 3.6 volts, it will automatically shut down. After the electricity is complete, the rechargeable mobile phone battery can be used longer.

18650 Lithium Ion Battery Repair Measures 1, remove your battery, remove it, solve it with temperature, the battery will greatly shorten the usage time in the case of temperature unstable, because the battery is no electricity and a considerable part of the lithium ion already With memory, this method can be used to release the memory, in winter, put it outside for a while, then go to the house. 2, there is another way, remove the battery, put a week, will slowly consume the electricity, and then use the machine to completely consume the electricity. Then all rinters, I will definite the charging time of your present, it is definitely very short, after the fullness, disconnect, repeated a few times, absolutely effective.
