Advantages and disadvantages of 18,650 lithium-ion batteries
Application of lithium-ion batteries 18650
The 18650 battery has an estimated lifespan of 1000 charges for its circulatory system. Due to its high capacity and value density, it is primarily utilized in laptop batteries. Its dependable performance makes it a popular choice in various electronic fields within China, including high-end flashlights, portable power sources, wireless data transmission, electric clothing and footwear, handheld devices, lighting control equipment, printers, industrial instruments, and medical equipment.
The advantages include:
When the capacity of the 18650 lithium-ion batteries is added up to the general battery capacity of Mach 800, the 18650 lithium-ion batteries can easily break through Mach 5000.
In normal use, the 18650 lithium-ion battery can be cycled more than 500 times, which is more than twice the life of an ordinary battery.
All 18,650 lithium-ion batteries are RoHS certified and meet strict safety standards. They boast high temperature resistance and a 65-degree discharge efficiency of 100%. To prevent short circuits, the positive and negative electrodes are separated, greatly reducing the risk of accidents. Additionally, a protection board can be included to safeguard against overcharging and overdischarging, ultimately prolonging the battery's lifespan.
The voltage of 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 be emptied, making it convenient to use.
One of the notable features of polymer batteries is their low internal resistance. Compared to traditional liquid batteries, polymer batteries have significantly lower internal resistance. In fact, the internal resistance of domestic polymer batteries can be as low as 35m, resulting in decreased battery self-consumption and increased standby time for mobile phones. These batteries also meet international standards and are a suitable choice for remote control models due to their ability to support large discharge currents. They are considered the top contenders to replace NIMH batteries in the near future.
The 18650 lithium-ion battery pack can be connected in series or combined.
Use laptop computers, walkie-talkies, portable DVD players, instruments, audio equipment, aircraft models, toys, video cameras, and digital cameras.
The cons are:
A major disadvantage of the 18650 lithium-ion battery is that it has a fixed volume, and it is hard to position on some notebooks or products because of its fixed volume. In some cases, this is an advantage, as compared to other polymer lithium-ion batteries and other lithium-ion batteries, it is a disadvantage.
