What battery cells are good for lithium battery PACK.energy storage battery for solar system manufacture

　　What kind of battery cell is better to do the lithium battery pack? Although there are configured lithium battery packs on the market, there are still quite a few people who like to assemble themselves by themselves.

　　There is no need for people who like to assemble the lithium battery pack by themselves. The next content is mainly for those who want to assemble lithium batteries by themselves but have not got started or just get started to understand the battery cells used.

　　The battles that assembled the lithium battery pack mainly include 18650 battery cells and lithium polymer cells. These two are also more common lithium battery packaging batteries.

　　18650 battery cell

　　The 18650 market is generally three yuan of lithium iron phosphate and lithium manganate.

　　The 18650 battery is generally cylindrical and generally packaged in steel shells. Because the lithium ion of 18650 is in a liquid state, it is like a cup filled with water, so 18650 can only be cylindrical.

　　The danger of 18650 is still high, because the packaging of 18650 is generally used for steel shells. If the manufacturer has problems when producing, it will cause explosion problems.

　　Lithium polymer cell

　　Lithium polymer cells are generally mixed with lithium cobaltate, lithium manganate, and ternary lithium. Through a certain proportion of the three mixtures, it is made with a certain process. The outer packaging is mainly using an aluminum plastic film, and the lithium material in the middle is paste. The shape can be customized.

　　The greatest safety problem of lithium polymer cells is that the leakage and short circuit may lead to the occurrence of drums. The most serious cases will cause burning phenomenon and cause flames.

　　Compare 18650 battery cells and lithium polymer battles

　　The 18650 battery cells and lithium polymer battles have begun to vary in raw materials. The raw materials of the 18650 battery cells include lithium iron phosphate, lithium manganate, and ternary. It is mixed with a variety of materials such as lithium cobaltate, lithium manganate, and sandy lithium. The former has a single raw material, while the latter is rich in raw materials.

　　The safety of the two is also very different. The polymer power core is likely to explode when the quality of the steel shell is packaged. However, the entry who wants to assemble is likely to be unable to distinguish whether the 18650 cells they have traded to pass the quality. For novices, the 18650 battery is difficult to get started. It is best to ask professionals to assemble on behalf of them.
