How to charge lithium battery

　　It should be noted in the use of a lithium battery that after the battery is placed, it enters the dormant state. At this time, the capacity is lower than the normal value, and the use time is also shortened. However, lithium batteries are easy to activate. As long as 3-5 normal charging and discharge circulation can activate the battery and restore the normal capacity. Due to the characteristics of the lithium battery itself, it determines that it has almost no memory effect. Therefore, the new lithium battery in the user's mobile phone does not require special methods and equipment during activation. Not only theoretically, from my own practice, it is best to use standard methods to charge from the beginning. For the "activation" problem of lithium batteries, many saying is that the charging time must be more than 12 hours, and repeatedly do it three times to activate the battery. This saying that "the first three charging must be charged for more than 12 hours" is obviously a statement from nickel battery (such as nickel -cadmium and nickel -metal hydride). So this statement can be said to be misunderstood at the beginning. There are very large differences in the charging and discharge characteristics of lithium batteries and nickel batteries, and it can be clearly told that all the serious formal technical materials I have reviewed emphasized that over -charging and over -discharge will be on lithium batteries, especially liquid lithium lithium lithium lithium lithium, Ion battery causes huge damage. Therefore, it is best to charge the charging according to the standard time and standard methods, especially do not perform ultra -long charging for more than 12 hours. Generally, the charging method introduced in the mobile phone manual is the standard charging method suitable for the mobile phone.

　　In addition, the mobile phone or charger of the lithium battery will automatically stop the charging after the battery is fully. There is no so -called "trickle" charging for more than 10 hours. In other words, if your lithium battery is full, it is also a white charging on the charger. And none of us can guarantee that the characteristics of the battery's charging and discharge protection circuit will never change and quality, so your battery will be hovering for a long time. This is another reason we oppose the charging. In addition, on some mobile phones, after a certain period of time charging, if you do not remove the charger, the system will not only stop charging, but also start discharge-charging cycle. Perhaps the manufacturer of this approach has its own purpose, but it is obviously not good for the life of batteries and mobile phones/chargers. At the same time, it takes a long time charging and often needs to be carried out at night. From the situation of my country's power grid, the voltage of many places at night is relatively high, and it fluctuates greatly. As mentioned earlier, lithium batteries are very delicate. It is much worse than that of nickel electricity in power and discharge, so this brings additional danger. In addition, another aspect that cannot be ignored is that lithium batteries are also not suitable for discharge, and over -discharge is also very unfavorable to lithium batteries. This leads to the following problems.
