Li-ion battery charging method you don’t know

The lithium-ion battery charging method you don’t know When buying a new mobile phone, the general lithium-ion battery manufacturer of the mobile phone will say that the first charge is charged for all 12 hours, but in fact many people who use lithium-ion batteries correctly do not understand , Then the author explains for everyone: When using lithium-ion batteries, it should be noted that after a period of time, the battery will enter a sleep state, when the capacity is lower than the normal value, the use time will be shortened. However, lithium-ion batteries are easily activated. Only after 3 to 5 normal charge and discharge cycles can the battery be activated and return to normal capacity. Due to the characteristics of lithium-ion batteries, it has almost no memory effect. Therefore, the user is not a special method and equipment in the activation process of the new lithium-ion battery. Not only in theory, but also in my own practice, the naturally activated charging method is the best from the beginning. Regarding the activation of lithium-ion batteries, many people say: The charging time must be more than 12 hours, repeated three times to activate the battery. The statement that the first three charging times exceeded 12 hours is obviously a continuation of nickel batteries (such as nickel-cadmium batteries and nickel-metal hydride batteries). So this is a misunderstanding in the first place. There is a big difference between the charge and discharge characteristics of lithium-ion batteries and nickel batteries. I can tell you clearly that all serious official technical documents I have read emphasize that overcharge and overdischarge can cause great harm to lithium-ion batteries, especially It is a liquid lithium ion battery. Therefore, it is best to charge according to the standard charging time and method, especially the charging time should not exceed 12 hours. In addition, the lithium-ion battery or charger automatically stops charging when the battery is fully charged. There is no trickle that lasts more than 10 hours when charging with a nickel coin charger. In other words, if your lithium-ion battery is charged, it will not work on the charger. No one of us can guarantee that the characteristics of the battery's charge and discharge protection circuit will never change, and the quality will never change, so your battery will be in danger for a long time in the future. This is another reason against prolonged charging. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
