How long is the life of a polymer lithium battery.

With the increasing global pollution, energy conservation and environmental protection have become the projects advocated by all walks of life, then how to save energy, how to be environmentally friendly? Starting from the products that people use every day, there are many products that pollute the environment on the market, and the management of these products is fundamental. In the battery market, the lithium battery is a supernova, which is quickly recognized by consumers because of its long service life, complete charge and discharge, no memory effect, and no pollution.

Since the electrolyte materials constituting the lithium ion battery are different, the lithium ion battery is also classified into a polymer lithium ion battery and a liquid lithium ion battery. The polymer lithium ion battery is the same as the positive and negative materials of the liquid lithium ion battery, and the battery works similarly, and the electrolytes are different from each other. The polymer lithium battery is light in weight, has high energy storage capability, good discharge performance, and can be formed into various shapes and has a long life. The electrolyte of the polymer lithium battery is a solid electrolyte, and the polymer lithium battery can cause various shapes to improve the specific capacity of the battery with respect to the liquid electrolyte of the liquid lithium ion battery.

So how long does the polymer lithium battery last? Under the international unified standard, the battery life is not expressed by time, but by the number of cycles, that is, the complete discharge of the electricity once, the general lithium battery is between 500 and 800 times, the A polymer battery can Up to 800 times. Therefore, the quality of the battery of the selected battery supplier will be guaranteed and the service life will be longer.

If a lithium-ion battery is used in a high-temperature environment, such as a temperature above 350C, the amount of battery stored will continue to decrease, resulting in a battery that does not last as long as it is in a normal temperature environment. When the battery is charged in such a high temperature environment, the battery will be damaged to a large extent, thereby affecting the service life of the battery. Even charging in a hot environment can cause different degrees of damage to the battery, so you should try to avoid charging the battery in a high temperature environment. If the battery is charged in a low temperature environment, such as in an environment below 40C, the battery will also be damaged.

If the polymer lithium-ion battery is not charged for a long time, it will reduce its life. Polymer lithium-ion batteries need to reach their ideal lifetime when the electrons remain flowing for a long time. The commercial production technology of polymer lithium-ion batteries in the world is not very mature, and now the market share is not high.

At present, the market price of polymer lithium ion batteries is higher than that of liquid lithium ion batteries. Compared with liquid lithium ion batteries, it has a long life and good safety performance. It is believed that there will be a large room for improvement in the near future.

A simple understanding, for example, a lithium battery used only half of the electricity on the first day, and then fully charged. If it is still the next day, it will be charged in half, and it will be charged twice in total. This can only be counted as one charging cycle, not two. Therefore, it is usually possible to complete a cycle after several charges. Each time a charge cycle is completed, the amount of power is reduced a little. However, the reduction is very small. After a high-quality battery has been charged for many cycles, it will still retain 80% of the original power. Many lithium-powered products are still used after two or three years, which is why. Of course, the life of the lithium battery will eventually need to be replaced.

The life of lithium batteries is generally 300 to 500 charge cycles. Assuming that the amount of electricity supplied by a full discharge is Q, if the power consumption is reduced after each charging cycle, the lithium battery can provide or supplement 300Q-500Q power in its lifetime. From this 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 you charge randomly, the number of times is variable. In short, no matter how charged, it is constant to add a total of 300Q ~ 500Q power. Therefore, we can also understand that the life of the lithium battery is related to the total charge of the battery, regardless of the number of times of charging. The effect of deep deep charge and shallow charge on lithium battery life is not much different.

In fact, shallow shallow charge is more beneficial for lithium battery. Only when the power module of the product is calibrated for lithium battery, it is necessary to deep charge. Therefore, products that use lithium-ion power supply do not have to be constrained by the process. Everything is convenient and can be charged at any time without worrying about affecting life.

If lithium is used in an environment above the specified operating temperature, ie above 35 °C, the battery's power will continue to decrease, ie the battery will not be as long as usual. If the device is to be charged at such a temperature, the damage to the battery will be greater. Even if the battery is stored in a hot environment, it will inevitably cause damage to the quality of the battery. Therefore, trying to maintain a favorable operating temperature is a good way to extend the life of the lithium battery.

If you use lithium battery in a low temperature environment, that is, below 4 °C, you will also find that the battery life is reduced. Some mobile phones' original lithium batteries are not charged even in low temperature environments. But don't worry too much. This is only a temporary situation. Unlike the use in high temperature environment, once the temperature rises, the molecules in the battery are heated and immediately return to the previous power.

In order to maximize the performance of a lithium-ion battery, it is necessary to use it frequently so that the electrons in the lithium battery are always in a flowing state. If you do not use lithium batteries frequently, please remember to complete a charging cycle for the lithium battery every month, do a power calibration, that is, deep charge deep charge once.
