Analysis of the correct charging method of 18650 lithium battery

The 18650 lithium battery is cylindrical and has liquid inside. Because of the battery design and material, the 18650 is suitable for high current. Therefore, almost all notebooks and electric vehicles are designed with 18650 batteries; only the super notebooks are energy-saving, so 18650 can be omitted. Instead, use polymer lithium batteries, especially tablet computers; digital cameras require high voltage and instantaneous high current for flash charging and discharging, so they can only use 18650 similar batteries, but they are slightly smaller. 1. When using 18650 lithium battery, it should be noted that after the battery is left for a period of time, it will enter the dormant state. At this time, the capacity is lower than the normal value, and the use time is also shortened. But the lithium battery is easy to activate, as long as 35 normal charge and discharge cycles can activate the battery and restore normal capacity. 2. Due to the characteristics of the 18650 lithium battery, it has almost no memory effect. Therefore, the new lithium battery in the user's mobile phone needs no special methods and equipment during the activation process. 3. It is best to charge according to the standard time and standard method, especially not to charge for more than 12 hours. Generally, the charging method analyzed in the instruction manual is the standard charging method. 4. 18650 lithium battery is also not suitable for overdischarge, and overdischarge is also very unfavorable for lithium batteries. 5. Smart charging: This is now considered an ideal charging management method. It follows the charging algorithm mentioned at the beginning of this section and is integrated in a small chip IC. The peripheral circuit is simple, stable and reliable. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
