Application of lithium-ion batteries 18650

The estimated lifespan of the 18650 battery is 1000 charges for its circulation system. 18650 manufacture Due to its high capacity and value density, it is primarily utilized in laptop batteries. Additionally, its stable performance makes it a popular choice in various network electronic technologies in China. Some common applications include high-end flashlights, portable power sources, wireless data transmission, electric heated clothing and footwear, handheld instruments, lighting control devices, printers and other industrial and medical equipment.

The advantages are:

The capacity of 18650 lithium-ion batteries is between Mach 1200 and 3600, and the general battery capacity is only about Mach 800. Adding up 18650 lithium-ion batteries, 18650 lithium-ion batteries can easily exceed Mach 5000.

Two, long-life 18650 lithium-ion batteries have a long service life and can be cycled more than 500 times, which is twice as long as ordinary batteries.

The 18,650 lithium-ion batteries have been certified as safe and environmentally friendly, with high temperature resistance and a discharge efficiency of 100% at 65 degrees. To ensure safety, the positive and negative electrodes are kept separate to minimize the risk of short circuits. Additionally, a protection board can be installed to prevent overcharging and overdischarging, thus prolonging the battery's lifespan.

The voltage of high-voltage 18650 lithium-ion batteries is generally 3.6V, 3.8V, 4.2V, which is significantly higher than the 1.2V voltage of nickel-cadmium and nickel-metal hydride batteries.

Since there is no memory effect in their own charging before the remaining power will not have to be emptied, the use is convenient.

Polymer batteries possess a low internal resistance, making them superior to traditional liquid batteries in this regard. In fact, the internal resistance of domestic polymer batteries can even dip below 35m, resulting in reduced self-consumption and longer standby time for cell phones. These highly efficient batteries also rival international standards and are particularly well-suited for high discharge current activities such as remote control models. As they continue to evolve and improve, polymer lithium batteries are emerging as the most viable substitute for NIMH batteries.

The 18650 lithium-ion battery pack can be connected in series or combined.

Electronic equipment includes laptop computers, walkie-talkies, portable DVD players, instruments, audio equipment, aircraft models, toys, video cameras, and digital cameras.

The cons are:

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. In contrast to other polymer lithium-ion batteries and other lithium-ion batteries, this shortcoming can also be viewed as an advantage. This has proven advantageous for some products with specific battery specifications.

If a relatively general battery, 18650 lithium-ion batteries may not be vulnerable to short circuits or information explosions as well as polymer lithium-ion batteries.

In order to prevent the battery from overcharging and discharging, the 18650 lithium-ion battery comes with a protective circuit. Obviously, these are necessary for lithium-ion batteries, since lithium-cobalt lithium-ion batteries are most commonly used. However, lithium-cobalt lithium-ion batteries cannot be charged at high currents, and their safety is poor.

In comparison to general battery production, the production conditions of 18650 lithium-ion batteries are higher, which undoubtedly increases production costs.
