Analysis of the advantages and disadvantages of 18650 cylindrical lithium-ion battery cells

Advantages of 18650 cylindrical lithium-ion battery cells 1. Long cycle life: The cycle life of 18650 lithium-ion batteries can reach more than 500 times, which is more than twice that of ordinary batteries. 2. Large capacity: The capacity of 18650 cylindrical lithium-ion battery cells 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-ion battery cell. If it is combined into a 18650 lithium-ion 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 the 18650 lithium-ion 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-ion 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. Disadvantages and stability of 18650 cylindrical lithium-ion battery cells: As for polymer lithium-ion batteries, 18650 lithium-ion batteries are prone to short circuits or explosions. Can not overcharge: 18650 lithium ion battery processing must have a protection circuit to prevent the battery from being overcharged and causing discharge. High cost: The processing conditions of the 18650 lithium-ion battery are high, which undoubtedly adds to the processing cost.
