18650 lithium-ion battery application
The 18650 battery life is theoretically charged 1000 times for the circulatory system. 18650 pack builder Because the capacity of the enterprise unit value density can be very large, most of them are used for laptop batteries. In addition, because of the stable working performance of 18650 in the work, it is widely studied and used in major network electronic technology fields in China: Commonly used in the production of high-grade light flashlight, portable power supply, wireless information data transmission, electric warm clothes, shoes, portable instruments, portable lighting control equipment, portable printers, industrial development instruments, medical instruments and so on.
Advantages:
Capacity 18650 lithium-ion batteries are generally between Mach 1200 and 3600, battery manufacturing machine and the general battery capacity is only about Mach 800, if the 18650 lithium-ion batteries are added up, 18650 lithium-ion batteries can easily break through Mach 5000.
long life 18650 lithium-ion battery has a long service life, and the cycle life can reach more than 500 times in normal use, which is more than twice the ordinary battery.
All 18,650 lithium-ion batteries are safe, non-explosive, non-flammable, non-toxic, non-polluting and RoHS certified. High temperature resistance, 65 degrees discharge efficiency 100%. To prevent battery short circuits, the positive and negative electrodes of 18,650 lithium-ion batteries are separated. So the possibility of a short circuit has been reduced to the limit. li ion battery construction The protection board can be configured to prevent the battery from overcharging and overdischarging, extending the battery life.
The voltage of high-voltage 18650 lithium-ion batteries is generally 3.6V, 3.8V, 4.2V, which is much higher than the 1.2V voltage of nickel-cadmium and nickel-metal hydride batteries.
there is no memory effect in their own charging before the remaining power will not have to empty, the use can be convenient.
Low internal resistance: The internal resistance of polymer batteries is less than that of ordinary liquid batteries. The internal resistance of the domestic polymer battery can be less than 35m, which greatly reduces the self-consumption of the battery, extends the standby time of the mobile phone, and can reach the level of international integration. Polymer lithium batteries that support large discharge currents are ideal for remote control models and are the most promising alternatives to NIMH batteries.
It can be connected in series or combined to form an 18650 lithium-ion battery pack.
Use a wide range of laptop computers, walkie-talkies, portable DVDS, instruments, audio equipment, aircraft models, toys, video cameras, digital cameras and other electronic equipment.
Cons:
The biggest disadvantage of the 18650 lithium-ion battery is that the volume has been fixed, and it is not well positioned on some notebooks or some products. Of course, this shortcoming can also be said to be an advantage, compared to other polymer lithium-ion batteries and other lithium-ion batteries is a disadvantage. And for some products with specific battery specifications, this has become an advantage.
18650 lithium-ion batteries can easily lead to short circuit or information explosion, but also related to polymer lithium-ion battery companies, if a relatively general battery, this main shortcoming is not so obvious.
The 18650 lithium-ion battery comes with a protective circuit that prevents the battery from overcharging and causing discharges. Of course, these are necessary for lithium-ion batteries, because most of the materials used in lithium-ion batteries are lithium-cobalt lithium-ion batteries, but lithium-cobalt lithium-ion batteries cannot be charged at high currents, and safety is poor.
18650 lithium-ion battery production conditions are high. Compared with the general battery production, the production conditions of 18650 lithium-ion batteries are higher, which undoubtedly increases the production cost.
