In theory, lithium batteries can be charged and discharged repeatedly.
In practice, the capacity of a lithium battery will decrease slightly with each cycle. The more it is cycled, the greater the reduction in capacity. Therefore, it is not recommended to charge and discharge the battery frequently.
The principle is: during charging, lithium ions will enter the graphite layer of the negative electrode. During discharge, lithium ions will detach from the graphite layer, forming electronic movement to generate current. However, even if the lithium ions are 100% detached from the graphite layer, there is a certain percentage that cannot be detached. Such continued accumulation will result in continued decline in capacity.
Can cell phone lithium batteries be recharged intermittently? I charge them for half an hour ata times I unplug them then charge them again, I only charge them for a short time each time and they won't. fully charged.
Let me tell you first. Frequently charging your phone won't do much harm, but draining the phone's battery and then recharging it will damage the battery. Today's cell phones use lithium-ion polymer batteries, which lack the "memory effect" common to nickel-chromium batteries of old.
So frequent charging will not damage the lithium battery itself. The lifespan of a lithium battery is generally 300 to 500 charge cycles. This cycle refers to the process from 0 to 100 and then from 100 to 0. As for whether it goes from 0 to 50 to 80 to 100 in the middle, or from 0 to 50 directly to 100, it has no effect on lithium batteries.
In addition, the lifespan of lithium-ion polymer batteries under normal conditionses is fixed, and a portion of the lifespan will be reduced each time a full charge cycle is performed. The charge cycle life of a new lithium-ion polymer battery is about 500 times.
But nowadays we usually don't know how to maintain their cell phone batteries. Many people use their cell phone while it is charging. This is not good, but it depends on the situation. If you read novels and follow the news while you load, you're fine.
But if you play games, watch videos and other software that consumes the CPU of the mobile phone while charging, it will have a certain impact on the battery of the mobile phone, and the heat of the phone may be too high and it may explode. Therefore, it is best not to play with your cell phone while charging, so that the battery lifeof your mobile phone does not run out too quickly.
Some people also say that the mobile phone must be fully charged when charging? In fact, for current lithium batteries, it is enough to keep the power of the mobile phone above 30%, and it is not necessary to fully charge it.
However, the battery of the mobile phone cannot be too low. When the mobile phone battery is too low, it is best to charge it in time. and you always play games, then the harm to the mobile phone is: Very significant, it will damage the battery performance of the mobile phone and shorten the life of the mobile phone.
No.
Lithium batteries have almost no memory effect, but they still have a memory effect.
For example: the battery memory effect is 300 times, and only 299 times remain after a single charge.
As some people said, without memory function, the battery will never break, ^_^.
Try charging when the phone tells you the battery is low.
Lithium-ion batteries cannot be depleted, as this may damage the battery.
