18650 Lithium iron phosphate, lithium manganate and ternary lithium manganate are widely available on the market.
18650 electric core is generally cylindrical and generally packaged with steel shell. Since the lithium ion of 18650 is liquid, just like a cup filled with water, 18650 can only be cylindrical.
The danger of the 18650 is still high, because the 18650 is usually packed with steel shells. If the manufacturer has problems during production, which leads to poor quality, it is easy to have explosion problems.
Lithium polymer core
Lithium polymer electric core is generally made of lithium cobalate, lithium manganate and ternary lithium. It is made by a certain proportion of the mixture of the three with a certain technological process. The outer packaging is important to use aluminum plastic film, and the lithium material in the middle is paste. The shape can be customized.
The biggest safety problem of lithium polymer electric core is that liquid leakage and short circuit may lead to bulge, and in the most serious case, it will cause combustion and flame.
