Which battery cell is better for lithium battery packs?

Which battery is more suitable for making lithium battery packs? Which battery is more suitable for making lithium battery packs? Although there are well-equipped lithium batteries available for purchase, there are still many people who like to assemble them together. For those who like to assemble lithium battery packs by themselves, there is no need to read this article. The rest are those who want to make their own lithium batteries but are not yet familiar with them. The batteries of the assembled lithium battery pack include 18650 batteries and lithium polymer batteries, which are also commonly used data for lithium battery packs. 18650 battery 18650 is widely used in lithium iron phosphate, lithium manganate and ternary lithium. 18650 batteries are usually cylindrical and are usually packaged in a steel box. Because the lithium ion of 18650 looks liquid, like a glass filled with water, the lithium ion of 18650 is only cylindrical. The risk in 18650 is still relatively high. Since the packaging of the 18650 is generally made of steel, if the manufacturer has a problem during the processing and the quality is not up to the standard, an explosion will occur. Lithium polymer batteries Lithium polymer batteries generally use a mixture of lithium cobaltate, lithium manganate, and ternary lithium. After a certain proportion of the three mixtures, after a certain process, the outer packaging is mainly made of aluminum plastic film, and the middle is lithium paste. The shape can be customized arbitrarily. The biggest safety problem of polymer lithium battery is that leakage and short circuit may cause bulge problems, and the most serious situation will cause burning and fire. Comparing 18650 batteries and lithium polymer batteries, the two original data of 18650 batteries and lithium polymer batteries are beginning to be different, the original data of 18650, lithium iron phosphate batteries, lithium manganese and ternary, etc., and lithium polymer The raw data of physical batteries are usually mixed data such as lithium cobalt oxide, lithium manganate and ternary lithium. The original data of the former is single, and the original data of the latter is rich. The safety of 18650 batteries is also very different. The 18650 battery may explode when the processing quality does not meet the standard because of its steel shell packaging. However, beginners who want to assemble 18650 batteries may not be able to tell whether the quality of the 18650 batteries they buy is good or bad. For beginners, the 18650 battery is more difficult and not recommended. The safety of lithium polymer batteries is higher than that of 18650 batteries. The packaging structure of the lithium polymer battery is that the outer layer is a layer of aluminum plastic film, and the outer layer is a layer of high temperature adhesive tape. The more serious accident phenomenon is the beginning of combustion, rather than a direct explosion. The energy density of lithium polymer batteries is also higher than that of 18650 liquid batteries. In short, when assembling lithium batteries, beginners in the assembly of lithium battery packs choose the best lithium polymer batteries. Because of their high energy ratio and high safety, the important thing is that high safety is the most important thing. After all, to protect their personal safety talents Do what you like better.
