Briefly describe the advantages and disadvantages of 18650 lithium-ion power batteries

The 18650 lithium-ion battery is one of the lithium-ion batteries and the first lithium-ion battery. 18650 is actually the size of a battery. Ordinary 18,650 batteries are divided into lithium-ion batteries and lithium iron phosphate batteries. In the 18,650 cells, nmp recovery system 18 indicate a lithium-ion battery diameter of 18 mm, 65 indicate a battery length of 65 mm, and 0 indicates a cylindrical cell.

Lithium-ion batteries 18650 have several advantages

An 18650 lithium-ion battery has a capacity of between Mach 1200 and 3600, while the typical battery capacity is only about Mach 800, and the 18650 lithium-ion battery can easily exceed Mach 5000.

In normal use, the cycle life of 18650 lithium-ion batteries can reach more than 500 cycles, n methyl 2 pyrrolidone solvent which is more than twice that of ordinary batteries.

In order to prevent the short circuit fault phenomenon in the battery system, 18650 lithium-ion batteries are separated at both the anode and cathode to ensure high safety technical performance. Therefore, there is little chance that it will short-circuit. With a protection board installed, students can also extend the battery's network life by preventing it from overcharging or overdischarging.

4 High voltage: 18650 lithium-ion batteries typically operate at 3.6V, 3.8V, and 4.2V, much higher than nickel-cadmium and nickel-metal hydride batteries' 1.2V voltage.

No memory effect, no need to empty remaining power before charging, nmp chemical easy to use.

Polymer batteries have a low internal resistance compared to ordinary liquid batteries. For domestic polymer batteries, this resistance can be as low as 35mω. This greatly reduces self-consumption and extends the standby time of mobile phones, reaching international integration standards. They are also suitable for large discharge currents, making them an ideal choice for remote control models and a promising alternative to NIMH batteries.

An 18650 lithium battery pack can be formed by connecting them in series or combining them together.

The use of a laptop, walkie-talkie, portable DVD player, instrument equipment, sound system equipment, model aircraft, toys, cameras, digital cameras, and other electronic technology.

18650 lithium-ion battery disadvantages

The biggest disadvantage of the 18650 lithium-ion battery is that the volume has been fixed, so it is not well positioned on some notebooks or some products. Although this shortcoming can be said to be an advantage, it can also be said to be an advantage compared to lithium polymer lithium batteries, which are customizable and can be customized in size. Furthermore, it has become a competitive advantage over other products with specified battery specifications.

In order to prevent overcharging and discharges, all 18650 lithium-ion batteries are equipped with a protective circuit. Of course, this is necessary for lithium-ion batteries. Lithium-ion batteries have this disadvantage as well, because they are made out of lithium cobalt oxide, and lithium cobalt oxide batteries are not able to charge at high currents, and they are not safe.

The production conditions of 18650 lithium-ion batteries are higher than those of general batteries, which undoubtedly increases the production cost.

The use of 18650 lithium-ion batteries

In the 18650 battery theory, 1,000 charge cycles were required for battery life. The large capacity of 18650 makes it ideal for notebook batteries; in addition, its work is exceptionally stable, making it widely used in every major electronic field: high-end flashlights, portable power supplies, wireless data transmission, warm clothes, shoes, portable instruments, portable lighting equipment, portable printers, industrial equipment, medical equipment, etc.
