The difference between Polymer lithium battery and lithium battery
2021-07-02
Lithium polymer batteries are characterized as follows relative to lithium ion batteries:
1, No battery leakage problem, the battery does not contain liquid electrolyte, the use of colloidal solid.
2,Can be made thin battery: to 3.6V 400mAh capacity, its thickness can be as thin as 0.5mm.
3,The battery can be designed in a variety of shapes.
4,Battery bending deformation: Polymer batteries can bend about 900 maximum.
5,Can be made into a single high voltage: the battery of liquid electrolyte can only be a few batteries in series to get high voltage, high polymer batteries.
6,Since it is liquid-free, it can be made in multiple layers in a single package to achieve high voltage.
7,Capacity than the same size lithium-ion battery twice as high.
The polymer lithium battery life:
Lithium battery life is generally 300 to 500 charge cycles. Assuming a full discharge to provide the power of Q, without taking into account the charge after each charge cycle to reduce the total of lithium in its life can provide or to supplement its 300Q-500Q of electricity. From this we know that if each with 1/2 to charge, you can charge 600-1000 times; if each with 1/3 to charge, you can charge 900 to 1500 times. And so on, if the random charge, then the number of uncertain. In short, no matter how charge, add a total of 300Q ~ 500Q into the power of this point is constant. Therefore, we can also understand: lithium battery life and the total charge of the battery, and the number of charging has nothing to do. Deep deep charge and shallow shallow charge for the lithium life of little difference.
In fact, shallow charge for lithium more benefits, only in the product's power supply module for the lithium to do calibration, have deep deep filling the need. Therefore, the use of lithium-powered products do not have to rigidly adhere to the process, all to facilitate the first, at any time charging, do not worry about the impact of life.
If lithium is used at temperatures above 35 ° C above the specified operating temperature, the battery power will be reduced continuously, ie, the battery will not run as long as usual. If at such temperatures, but also for the device to charge, then the battery damage will be greater. Even in a hot environment, storage batteries, will inevitably lead to the corresponding damage to the quality of the battery. Therefore, try to maintain the appropriate operating temperature is a good way to extend the life of lithium.
If the low-temperature environment, that is below 4 ° C in the use of lithium, the same will also reduce the use of battery time, and some of the original lithium battery in the low-temperature environment, and even charge is not power. But do not worry too much, this is only a temporary situation, unlike the use of high-temperature environment, once the temperature rises, the molecules in the battery heated to immediately restore to the previous power.
