Disadvantages of 18650 battery cells

    1.Subside: The storage capacity of all lithium-ion batteries will slowly subside, which is related to the utilization frequency and operating temperature.  

    2.Difficult to recycle: it is basically not recycled.

    3.Intolerance to moderate charging and over-discharge: When overcharging, the lithium ions embedded in the appropriate amount will be permanently fixed in the crystal structure, and there is no way to release them again, which can cause short battery life.When over-discharging, too many lithium ions are de-embedded in the battery, which can cause the crystal structure to collapse, thereby shortening the life span.

    4.The nose does not move: Because the basic shape and size have long been fixed, it is difficult to have a polymer battery. The nose is changeable. Of course, this is also the upper hand. Fixed specifications symbolize interchangeability.
