Soft bag. According to the official website of Ningde Times, we learned that the soft packaging of lithium batteries is customized according to the specific size of the PACK box. The cells are arranged in various battery layouts to fully utilize the internal space of the case. battery box. Because soft battery is a battery in which the positive and negative electrode materials are separated by a membrane or composite membrane to form a foldable and foldable package. Soft batteries have the advantages of small size, high energy density and high flexibility, so they are suitable for applications in electric vehicles and power tools with limited space.
Actually, lithium batteries are divided into flexible packaging and rigid packaging.
Soft bag means the case is soft and there will be marks when you scratch itere with your nail. Hard bags are those with aluminum shells and steel shells, and the outer shell is very hard. They all have their own advantages. See the product selection.
Lithium polymer batteries, ternary batteries, manganese and lithium iron phosphate batteries are simply different in the internal composition of the cells. Chemical substances are added as needed to modify certain characteristics of the battery. Such as voltage, temperature resistance.
The cylindrical is round like nickel metal hydride, but the voltage is 3.7V.
