Currently, most of the smart technology devices in people's own hands need lithium batteries to power them. But how exactly should lithium batteries be used correctly?

Mistake 1: The first time you use the battery, you must be fully charged, fully charged, so repeat three times to activate the battery!

Answer: lithium batteries are not used for a long time (usually at least 3 months or more to be called long-term), it is true that the electrode material will produce passivation leading to performance degradation, and it is also true that the above method can be used to lift the passivation. But this is not necessary, because lithium batteries as long as with continuous use, electrode passivation without deliberate activation can also slowly disappear. So, unless you are really bored, you can activate it deliberately.

Mistake 2: Playing with cell phone while charging, the battery is charging and discharging at the same time, which is harmful to the battery and doubles the radiation.

Answer: Playing with a cell phone while charging does charge and discharge the battery at the same time. Light use of the cell phone does not do much harm to the battery. If you play games heavily, you really need to be careful because the heat from charging the phone increases and playing the phone heavily is also very hot. When the two are superimposed, the heat increases a lot, and lithium batteries have an optimal operating temperature. If it gets too hot, the life of the lithium battery will decrease a lot, which is really harmful. As for the last sentence, it is incorrect to say that the radiation increases exponentially, because charging a cell phone does not increase the radiation. It only increases the radiation when calls are coming and going. In order to keep the call smooth when it comes in, the cell phone must increase its transmit power in order to communicate with the base station, so the radiation increases.

Mistake 3: Batteries have a limit on the number of times they can be charged and discharged, so you can reduce the number of times they are consumed by using them until they are completely dead before you start charging them, and charging them until they are fully charged, with as little interruption as possible in between.

Answer: Batteries do have a limit on the number of times they can be charged and discharged, but that's not how it's calculated. It says the number of times is complete once. For example, if we charge our cell phone from 30% to 70% in one charge, then it is only 0.4 times, not 1 time. So, we don't need that to save times at all.

Mistake 4: The first three times the system is charged, it must be charged for 12 hours, otherwise the performance of the battery will be permanently degraded.

Answer: This is usually related to the activation of the battery as mentioned earlier, but, nowadays, cell phones support fast charging, and usually an hour is enough for a full charge. And the battery overcharge and overdischarge protection circuit inside the cell phone will automatically cut off the charging current when fully charged, so even if you plugged in 12 hours and people fully charged and unplugged is an effect. So there is no need. This must be charged for 12 hours is mainly for nickel-metal hydride batteries, because nickel-metal hydride batteries have a memory effect, if you often do not fully charged to start discharging, or do not put a late charge on charging, nickel-metal hydride batteries will memorize the capacity, resulting in a reduction in capacity. But this effect of lithium batteries has been negligible.
