Comparison of polymer lithium battery life and lithium battery life

Appropriate point of view: polymer lithium battery is actually a kind of lithium battery, so you don't need to worry too much. You will understand the life of lithium battery by carefully knowing the life of lithium battery. The life of a lithium battery is related to the frequency of completion of the charging cycle of a polymer lithium battery, but not directly related to the charging frequency. We can change our point of view. For example, a lithium battery uses only half of its power on the first day, and then fills it with electricity. If the situation persists the next day, charge half of the charge and charge it twice in total. This can only be counted as one charging cycle, not two. Therefore, it may usually take several times of charging to complete a cycle. Every time a charging cycle is completed, the power will drop a little bit. However, the reduction is very small. High-quality batteries will still retain 80% of the original power after being charged for many cycles. Many lithium battery-powered products are still used as usual after two or three years. This is the reason. Of course, the lithium battery has to be replaced at the end of its life. The life of a lithium battery is generally 300 to 500 charging cycles. Assuming that the power given by a one-time complete discharge is Q, if the reduction in power after each charging cycle is not considered, the lithium battery can give or supplement 300Q-500Q of power during its life. So we know that if you charge 1/2 each time, you can charge 600-1000 times; if you charge 1/3 each time, you can charge 900-1500 times. By analogy, if it is charged randomly, the frequency is variable. In general, no matter how charged, it is constant to add a total of 300Q to 500Q of power. Therefore, everyone can also understand this: the life of a lithium battery is related to the total charge capacity of the battery, and has nothing to do with the charging frequency. The impact of deep discharge and shallow charge on the life of the lithium battery is not very different. In fact, shallow charging and shallow charging are more beneficial for lithium batteries. Only when the product's power module is calibrated for lithium batteries, it is necessary to deep discharge and deep charge. Therefore, products powered by lithium batteries do not need to be limited to the operation process. Everything is convenient and can be charged at any time without worrying about affecting life. If the lithium battery is used in an environment that is higher than the specified operating temperature, that is, 35°C or higher, the battery's power will continue to decrease, that is, the battery's power supply time will not be as long as before. If the device needs to be charged under such working temperature, the damage to the battery will be even greater. Even if the battery is stored in a hot environment, it will cause corresponding damage to the quality of the battery. Therefore, it is a good way to extend the life of lithium batteries to maintain a suitable operating temperature as much as possible. If the lithium battery is used in a low temperature environment, that is, below 4°C, the battery life will also be reduced. The original lithium battery of some mobile phones cannot even be charged in a low temperature environment. But don't worry too much. This is only a temporary situation, which is different from the use in a high temperature environment. If the molecules in the battery are heated once the working temperature rises, it will immediately return to the previous power. If you want to maximize the effectiveness of lithium batteries, you must use them frequently to keep the electrons in the lithium battery in a flowing state. If you don't use lithium batteries often.
