18650 lithium battery with polymer battery

Source: 2020 - 04 - 19 21:07 hits: 18650 lithium battery is widely application in the real life, with the continuous development of power batteries and upgrade, this kind of battery is more popular with people, will appear in a variety of devices. Polymer lithium battery and lithium battery than 18650 lithium batteries are very different, the ancestors of this by outside daub some polymer battery, so that you can make the battery have longer service life, there is a very has the advantage part is' polymer, electrolyte electrolyte injection form of this part, let's take a look at the 18650 lithium polymer batteries and battery. Polymer lithium battery 1. Safe if used in harsh environment, such as environmental temperature is too high, charging time is too long, will cause some big in lithium battery internal reactions, there are a lot of gas, so there will be a danger of explosion. The traditional 18650 lithium batteries in use are likely to exist the problem, when the internal pressure reaches a certain extent, steel shell would burst, causing serious safety accidents. It is for this reason, when we test 18650 lithium batteries, we usually in testing outside establish a protective layer, someone must not enter in the testing process. Compared with 18650 lithium-ion battery, polymer battery without this kind of situation, even in some condition is not very good, is not easy to explosion, the worst is burning. As a result, polymer battery safer than 18650 lithium batteries. 2. Whether can customize the biggest advantages of lithium battery can be designed according to customer demand, so there is no unified standard. So far, the lithium battery industry is only a basic standard models, namely 18650 lithium-ion batteries, the rest are designed according to customer's requirements. 3. Low energy density of lithium battery capacity can reach about 2200 18650 mAh, the energy density is about 500 Wh/L, polymer battery mass production can be nearly 600 Wh/L, but this kind of battery is one of the biggest problems in the production cost is higher than other types of many, because it can be designed according to customer demand, so should include research and development costs. In addition, due to the different shapes and kinds, all kinds of fixture are standard parts in the manufacturing process. Another disadvantage is that polymer battery is not everything, it is also the result of the flexible design. Usually need to redesign a for customers, so that you can adjust the original 1 mm difference.
