Lithium power battery charging voltage.best portable power station

　　Generally, the battery voltage of the mobile phone is 3.7V, but the voltage of the general charger is written with 5V, but it will not affect the use, because there is no 3.7V mobile phone charger for sale. New battery should not be over -charged

　　Many saying about the "activation" of the new lithium -ion battery is: 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 continuation of nickel battery (such as nickel -cadmium and nickel -metal hydride). So this statement can be said to be misunderstood at the beginning. The charging and discharge characteristics of lithium batteries and nickel batteries are very different, and they can tell you very clearly that all serious formal technical materials emphasize that over -charging and over -discharge will cause huge huge on lithium batteries, especially liquid lithium -ion batteries. harm. Therefore, it is best to charge the charging according to the standard time and standard methods, especially not to perform ultra -long charging for more than 12 hours.

　　So does the battery need to be activated? The answer is yes, it needs to be activated! However, this process is done by manufacturers, has nothing to do with users, and users are unable to complete. The real activation process of lithium batteries is this: lithium-ion battery shells instill electrolyte-seal-turned into a constant voltage charging, and then discharge. So far, this is the activation process-tolerance, that is, the lithium-ion battery has been activated after the factory is left. In addition, the activation process of some batteries requires the battery to be in a state of opening, and then seal after activation. Unless you own the battery production equipment, how to complete it?

　　But why do some products say that the user is used in the first three times to fully charge the mobile phone? Isn't this activation? In fact, this is the case. In the battery, it will be sold, and then in the hands of users, it will go through a period of time, one month or several months. In this way, the electrode material of the battery will be "passivated". At this time At normal values, the use time also shortened. However, lithium batteries are easy to activate. As long as 3-5 normal charging and discharge cycles can be activated, the battery can be activated to restore the normal capacity. Due to the characteristics of the lithium battery itself, it determines that it has almost no memory effect. Therefore, the user's new lithium battery does not require special methods and equipment during activation.
