What are the advantages and disadvantages of 18650 cylindrical lithium battery cells?

Advantages of 18650 cylindrical lithium battery cells 1. Long cycle life: The cycle life of 18650 lithium batteries can reach more than 500 times, which is more than twice that of ordinary batteries. 2. Large capacity: The capacity of the 18650 cylindrical lithium battery cell is generally between 1200mah and 3100mah. It is important to know that the general battery capacity is only about 800. This is just a single 18650 cylindrical lithium battery cell. If it is combined into an 18650 lithium battery pack, it is not a problem to break through 5000mah. 3. High safety performance: In order to prevent battery short-circuit phenomenon, the positive and negative poles of 18650 lithium battery are separated. Therefore, the short-circuit phenomenon may have been reduced to the extreme. High safety performance, no explosion, no combustion. 4. High voltage: The voltage of 18650 lithium batteries is generally above 3.6 and 3.7, which is much higher than the 1.2V voltage of nickel-cadmium and nickel-hydrogen batteries. 5. No memory effect: recharge and discharge, easy to use. The shortcomings and stability of the 18650 cylindrical lithium battery cell: As for the polymer lithium battery, the 18650 lithium battery is prone to short-circuit or explosion. Can not overcharge: 18650 lithium battery processing must have a protection circuit to prevent the battery from being overcharged and causing discharge. High cost: The processing conditions for 18650 lithium batteries are high, which undoubtedly adds to the processing cost.
