From:CTECHI GROUP Limited     Release time:2018-11-08

Overview:Theorical life of 18650 battery for is 1000 circles. Because of the large capacity per unit density, most of 18650 batteries are used for laptop batteries. In addition, 18650 is widely used in various electronic fields because of its excellent stability in work: high-end flashlight, portable power supply, wireless data transmitter, portable instruments and instruments, portable lighting equipment, and so on.

In addition, 18650 is widely used in various electronic fields because of its excellent stability in work: high-end flashlight, portable power supply, wireless data transmitter, portable instruments and instruments, portable lighting equipment, and so on.


18650 means 18 millimeters in diameter and 65 millimeters long. The number 5 battery is 14500, 14 millimeters in diameter and 50 millimeters long. Generally 18650 batteries are used more in industry and less in civilian use.


18650 is only the size of the battery model, according to the type of battery can also be divided into 18650 Li Socl2 Rechargeable Battery, 18650 Lithium Thionyl Chloride Battery, 18650 Limno2 Rechargeable Battery Pack, 3.2v 1000mah 18500 Lithium Phosphate Rechargeable Battery.



Repair Methouds of 18650 lithium battery:


The principle of lithium battery repair method 1: the metal surface of lithium battery used for a long time will be oxidized to a certain extent, resulting in poor contact between mobile phone battery and mobile phone, shorter use time of lithium battery, and the use of rubber Sassafras or other cleaning tools can erase rusty substances on the surface, so that the contact between battery and mobile phone is better.

Li Socl2 Rechargeable Battery

The principle of lithium battery repair method 2 is that low temperature can change the electrolyte inside the lithium battery and promote the chemical reaction of the newly frozen battery. The use of lithium battery is actually a charge and discharge process. During this period, the negative charge and the positive charge are interacted. The reason why batteries are becoming less and less useful is that at normal room temperature, the internal kinetic energy of electrons is relatively large, so the batteries are in active state and leakage is relatively frequent. When lithium batteries are placed in low temperature environment, the micro-structure of lithium film and electrolyte on the surface of lithium batteries and their interface will change significantly, which will cause the interior of the batteries to be temporarily inactive and the leakage current to be reduced. Therefore, after recharging, the waiting time of the mobile phone will increase.


The cycle life of lithium battery is more than 600 times. If charged more times, the thermal movement of the molecule will gradually destroy the internal molecular arrangement and structure, and the storage charge efficiency will gradually decrease. "The refrigeration process can easily destroy the original internal structure of the battery. It may increase the capacity to charge in a short time, but long-term use may not be effective." Once the microstructures of lithium batteries are destroyed, it is impossible to recover completely. Long-term use of this method will accelerate the loss of mobile phone batteries.


The third principle of lithium battery repair method is that deep discharging of mobile phone is to achieve deeper recharge by depleting internal electric energy, which requires some unconventional methods. Find a way to connect the cell phone to a 1.5V small light bulb. The electricity inside the lithium battery will be transmitted to the small light bulb until all the light is shining. "Mobile phones need to slowly consume electricity 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 turn off. The battery can be used for a longer time after the battery is discharged.
