Flexible packaging refers to the outer packaging material of lithium batteries
The outer packaging materials are classified into steel shell (18650 type), aluminum shell (old lithium battery). mobile phone), flexible packaging in aluminum plastic film. (Most smartphones now use it)
The performance difference between soft bags and other packaging materials mainly lies in safety performance. The safety performance of soft bags is better when the internal air pressure is too high, sealing. The sides will break and not explode.
I hope to adopt it, thank you!
What do the numbers on soft batteries mean?
Soft batteries. 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 according toVarious 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.
In addition to the basic parameters of voltage and capacity, a string of numbers mainly represents the model or manufacturer number of thelithium cell .
Battery cells are divided into three types: aluminum shell batteries, soft package batteries (also called "polymer batteries") and cylindrical batteries. packed itsoft ge means that the outer packaging material of the lithium battery is aluminum-plastic film, and there are also copper-plastic film and steel-plastic film.
Usually, mobile phone batteries use aluminum shell cells, digital products such as Bluetooth mainly use soft-packaged cells, and laptop batteries use series-parallel combination of cells cylindrical.
Home wiring note:
1.L means live wire, N means neutral wire, also called neutral wire, usually red, yellow and Green. used Among these three wire colors, the neutral wire uses the blue wire For the socket, the right jack is the live wire and the left jack is the neutral wire.
2. Usually, the installation of interior circuits is: left zero, right light, intermediate ground, represented by leall, L is the live wire, N is the neutral wire. Represented by color: red is the live wire, blue is the neutral wire, and the two-tone yellow and green wire is ground.
3. The wire joint should be tightly wound, smooth and without thorns. Before disconnecting the wire, press it with a steel wire, then wind it up to the opening to ensure the wire is disconnected at the wire. Seal. When connecting two insulated wires, you need to peel the insulation off the ends of the wire, wipe the inner core of the wire, then twist and solder the ends of the wire.
4. When the wire is connected to a switch, fuse or other equipment, a special connector must be soldered to the end of the wire. The direction of the ring should be consistent with the tightening direction of the screws. to prevent tightening the screw cap from causing loosening of the thread.
