With the increasingly serious global pollution, energy conservation and environmental protection has become advocated by all sectors of the project, then, how to save energy, how to environmental protection? People should start from the daily use of products, there are now a lot of products on the market pollution of the environment, from these products governance for the fundamental. In the battery market, lithium battery is a super star, by virtue of its long life, complete charge and discharge, no memory effect, no pollution and other characteristics of the market quickly occupied by consumers.

Due to the differences in the electrolyte materials used to make the lithium-ion battery, the lithium-ion battery is also classified as a polymer lithium-ion battery and a liquid lithium-ion battery. Polymer lithium-ion battery have the same anode and cathode materials as liquid lithium-ion battery, and batteries work in a similar way, with different electrolytes. Polymer Lithium batteries are lightweight, have high energy storage capacity, excellent discharge performance and can be made into a variety of shapes, and have a long life. The polymer lithium battery has a solid electrolyte, which can be shaped to improve the specific capacity of the battery compared to the liquid electrolyte of the liquid lithium-ion battery.

So how long do Polymer Lithium batteries last? Under the international standard, battery life is not expressed by time, but by cycle number, that is, complete discharge computing once, the general Lithium Polymer Battery is between 300-500 times, grade A polymer battery can reach 500 times. So choose a good battery supplier battery quality will be guaranteed, the service life will be longer.

If lithium-ion battery is used in high temperatures, such as 60 °C or higher, the battery will continue to store less power, which means it won’t last as long as it would in normal temperatures. In this high temperature environment to charge the battery, the battery will suffer a large degree of damage, which affects the battery life. Charging even in a hot environment can cause varying degrees of battery damage, so you should try to avoid charging the battery at high temperatures. If need to use in high temperature, then must customize 85°C high-temperature battery. Charging a battery at low temperatures, such as BELOW-20C, can also cause battery damage.

If the polymer lithium-ion battery is not charged for a long period of time, its life will be reduced. Polymer lithium-ion batteries need to be in a state of constant flow of electrons to achieve their ideal life.

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

The life of Lithium Polymer battery is related to the charge cycles, but not directly to the charge numbers.

A simple understanding, for example, is that a piece of lithium-ion battery uses half as much power on the first day and then recharges it full. If you do it again the next day, charge it when use it in half, then the twice charge should count as one charge cycle, not two. As a result, it can often take several recharges to complete a cycle. Each time a charge cycle is completed, the power is reduced a little bit. But the reduction is so small that high-quality batteries retain 80% of their original charge after many cycles, which is why many lithium-ion polymer battery power-supply products are still in use after two or three years. Of course, lithium-ion polymer batteries eventually need to be replaced.

Lithium-ion batteries typically have a lifetime of 300 to 500 cycles. Assuming Q is the charge provided by a complete discharge, lithium-ion batteries can supply or supplement 300Q-500Q over their lifetime, regardless of the reduction in charge after each charge cycle. From this we know that if you charge it with 1/2, you can charge it 600-1,000 times; if you charge it with 1/3, you can charge it 900-1,500 times. By analogy, if the charge is random, the number of times is variable. In short, no matter how you charge it, the total amount of electricity added up to 300Q ~ 500Q is constant. So, we can also understand: lithium-ion battery life is related to the total charge capacity of the battery, and charge times have nothing to do. The effect of deep charging&discharging and shallow charging&discharging on the life of lithium battery is similar.

In fact, shallow charge&discharge is more beneficial to the lithium polymer battery, only in the product’s power module for Lithium Battery calibration, deep charge& discharge is necessary. Therefore, the use of lithium-powered products do not adhere to the process, all in the first convenience, ready to charge, do not have to worry about the impact of life.

If the lithium battery is used above the specified operating temperature, that is, above 60 °c, the battery power will be continuously reduced, that is, the battery power supply time will not be as long as usual. If you have to charge the device at this temperature, the damage to the battery will be even greater. Even if the battery is stored in a hot environment, it will inevitably lead to corresponding damage to the battery quality. Therefore, as far as possible to maintain the appropriate operating temperature is a good way to extend the life of lithium battery.

If the low temperature environment, that is-20 °c below to use of lithium-ion batteries, the same will find that the use of the battery time is reduced, some phones of the original lithium-ion in the low temperature even can not be charged. But don’t worry too much, this is only a temporary situation, different from the use of high temperature environment, once the temperature rises, the molecules in the battery heated, immediately back to the previous electricity.

To get the most out of the lithium-ion battery, it needs to be used regularly to keep the electrons flowing. If you do not often use the lithium-ion battery, please remember to complete a monthly lithium-ion battery charge cycle, do a charge calibration, that is, deep charge&dicharge once.
