A brief description of the advantages and disadvantages of 18650 lithium-ion power batteries is provided

There are two types of lithium-ion batteries: 18650 lithium-ion batteries and 18650 lithium-ion batteries. Ordinary 18,650 batteries can also be divided into lithium-ion batteries and lithium iron phosphate batteries. 18650 manufacture Among the 18,650, 18 correspond to a lithium-ion battery with a diameter of 18 mm, 65 to 65 mm, and 0 to a cylindrical cell.

18650 lithium-ion batteries have several advantages

Its capacity is usually between Mach 1200 and 3600, while the typical lithium-ion battery's capacity is only about Mach 800, and the 18650 lithium-ion battery can easily exceed Mach 5000.

In normal use, 18650 lithium-ion batteries can be cycled more than 500 times, which is more than twice as long as ordinary batteries.

A high level of safety technical performance for 18650 lithium-ion batteries: To prevent the short circuit fault phenomenon in the battery system, the cathode and anode of 18650 lithium battery are separated. Thus, the probability of it short-circuiting is minimal. It is possible to prevent the battery from overcharging and overdischarging by installing a protection board, which allows students to extend the battery's life as well.

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

No memory effect, no need to empty the remaining power before charging.

One notable advantage of polymer batteries is their low internal resistance. Compared to traditional liquid batteries, the internal resistance of polymer batteries is significantly reduced. In fact, domestic polymer batteries can have an internal resistance lower than 35mω. This greatly minimizes battery self-consumption and extends the standby time of mobile phones, making it comparable to international standards. Additionally, polymer lithium batteries are capable of supporting large discharge currents, making them an ideal choice for remote control models and a promising alternative to NIMH batteries.

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

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

The disadvantages of 18650 lithium-ion batteries

As a result of its fixed volume, the 18650 lithium-ion battery is not well positioned on some notebooks or other products. In comparison to other lithium polymer lithium batteries, which can be customized and changed in size, this shortcoming can also be said to be an advantage. This has also become a competitive advantage over some products that have specific battery specifications.

The 18650 lithium-ion battery is manufactured with a protective circuit to prevent overcharging and discharge. Of course, this is a necessary feature for lithium-ion batteries. As lithium-ion batteries are made of lithium cobalt oxide, this is also a disadvantage, and lithium-ion batteries made of lithium cobalt oxide cannot be charged at high currents, which results in poor safety and inefficiency.

There are high production conditions for 18650 lithium-ion batteries. As compared with general battery production, the production conditions for 18650 lithium-ion batteries are higher, which undoubtedly increases the cost of production.

An 18650 lithium-ion battery is used as a power source

There are 1,000 charge cycles in the 18650 theory of battery life. The large unit density capacity of 18650 makes it ideal for notebook batteries, and the high stability of the 18650 battery makes it widely used in all major electronic fields: portable power supplies, wireless data transmissions, warm clothing, shoes, portable instruments, portable lighting, portable printers, industrial equipment, medical equipment, etc.
