Safety considerations on lithium-ion batteries

Source: 2020 - 03 - 28 and clicks: time use lithium battery notice the note: when using lithium battery, the battery should be paid attention to after a period of time will enter a dormant state, when the capacity is lower than normal, use time will be shortened. However, the lithium battery is easy to be activated. 3 - to charge and discharge normally After five times, can activate batteries, back to normal capacity. Due to the nature of the lithium battery, they will have little impact on memory. As a result, the new lithium ion battery does not need special method or equipment to activate the user's mobile phone. Not only in theory, but in my own practice, best use standard cost method from the start. There're a lot about the 'activate' lithium ion battery, charging time must be more than 12 hours, and repeat three times to activate the battery. 'the first three time charge need more than 12 hours' this sentence is obviously a continuation of nickel cadmium battery and nickel metal hydride batteries. So it is misunderstood from the start. Lithium battery charge and discharge characteristics are very different from nickel battery, it can be very clear you, all my serious formal technical information emphasizes the excessive charging and excessive charging can do a lot of lithium batteries, especially liquid lithium ion battery. Therefore, it is best to according to the standard and method of charging time, especially the charging time can't more than 12 hours. Generally speaking, the mobile phone specification described in the way of charging is the charging standard for mobile phones. In addition, mobile phone or lithium ion battery charger will automatically stop after a full charge. There is no such thing as' a trickle nickel battery charger that persists for more than 10 hours. That is to say, if your lithium battery fully charged, the charger is white. But also cannot guarantee the battery charge and discharge protection circuit will never be destroyed, so your battery may be in danger for a long time. This is another reason we oppose charging for a long time. Charging for some phones, if after a period of time still not unplug chargers, never stop charging system not only, also will begin to discharge. The manufacturer of this method may have their own purpose, but it apparently does not favor the battery and the lifetime of the cell phone/charger. In addition, the charging takes a long time for a long time, usually at night. In China's power grid, for example. In many places, a high voltage in the night, volatile. As mentioned earlier, lithium battery is very fragile. Compared with nickel battery, it bear the ability to charge and discharge fluctuations far worse, that leads to the additional risk. In addition, another aspect is that nots allow to ignore, lithium battery is not suitable for discharge, the lithium battery is very bad.
