Teach you 18650 lithium-ion battery repair method battery life theory is 1000 times. As a large density of the unit, most of the laptop batteries, in addition, 18650 is very good in security features, widely used in major electronic categories: commonly used in advanced light flashlight, portable electric, wireless data transmission, electrical thermal clothing , Shoes and portable instruments, portable lighting, portable printers, industrial equipment, medical equipment, etc. 18650 means a diameter of 18 mm, length 65 mm.

The type of number of 5 batteries is 14,500, 14 mm in diameter, 50 mm in length. In general, 18650 batteries are used for industrial, less for civil. Ordinary battery is used for laptop batteries and advanced flashlights.

18650 is only the size of the battery type, according to the type of battery, the lithium ion 18650, lithium iron phosphate 18650, hydrogenated nickel 18650 (very rare), ordinary lithium ion 18650. The working principle of the charging and discharge principle lithium-ion battery is charging and discharging. When the battery is charged, the lithium ion is formed in the battery positive electrode, and the lithium ion reaches the negative electrode through the electrolyte.

Carbon, that is, the negative electrode, a layered structure having many micropores, and the lithium ion reaching the negative electrode is embedded in the microporous of the carbon layer. The more lithium ions are embedded, the greater the charging capacity. Similarly, when the battery is discharged (we use the battery process), the lithium ions embedded in the negative electrode carbon will come out and return to the positive electrode.

The more the lithium ions returns to the positive electrode, the greater the discharge capacity. We usually say battery capacity refers to discharge capacity. In 18650, the lithium-ion battery is not difficult to see that during the charge and discharge of the lithium ion battery, the lithium ion is in a motion state from the positive electrode to the negative electrode.

If we compare lithium-ion batteries into a rocking chair, the two ends of the rocking chair are the two poles of the battery, and the lithium ions are like an excellent athlete, and they will move back and forth in both ends of the rocking chair. Therefore, experts have a cute name to lithium ion batteries: rocker chair. 18650 Lithium Ion Battery Correction Principle: Principle of Lithium Ion Battery Calibration 1: It will have a certain degree of oxidation for a long time for a long period of time, leading to mobile phone batteries and mobile phone, and lithium-ion batteries in a short time.

Use, but use eraser or other cleaning tools to raw rusty surface substances, let better battery and mobile phone. Lithium-ion battery correction method two principles: Low temperature can cause lithium ion battery electrolyte attack changes, promote chemical reactions after battery attack. The application process of lithium-ion batteries is actually a charge and discharge process.

During this time, negative charges and positive charges in the battery collide with each other. The battery has become more and more useful, because in normal room temperature, the internal kinetic energy of electrons is relatively large, so the battery is inactive, and the leak is more frequent. However, when a lithium ion battery is placed in a low temperature environment, the lithium ion battery electrolyte surface of the lithium film is electrolyte, and the surface of their interface, it will change significantly, resulting in a reduction in battery interim activity and leakage current.

So after charging, the wait time of the mobile phone will increase. The lithium-ion battery has a circulating life of approximately 600 times. If the amount of charge is too large, the thermal movement of the molecule will gradually destroy the microstructure of its internal molecules, and the power of the storage charge will gradually decrease.

However, the freezing process tends to damage the original internal structure of the battery, which may add the ability to charge in a short period of time, but may have no benefits for long-term use. Once the microstructure of the lithium-ion battery is destroyed, it is impossible to completely recover, and use this method for a long time to accelerate the loss of mobile phone batteries.
