Lithium-ion battery assembly steps and polymer lithium-ion battery assembly methods. Lithium-ion battery assembly and processing equipment is just a shorthand term; the more detailed explanation is that each step in manufacturing a lithium-ion battery involves several stages, from the lithium-ion battery paper machine, to the lithium-ion battery sorting machine, then the lithium-ion battery spot welding machine, followed by the comprehensive testing instrument, and finally the aging chamber. Below, we will introduce the polymer lithium-ion battery assembly method.
Polymer lithium-ion battery assembly method
1. Data Calculation
When assembling polymer lithium-ion battery packs, you first need to calculate the product size and required load capacity of the lithium-ion battery pack. Then, you need to calculate the capacity of the lithium-ion battery pack to be assembled based on the required capacity of the product. Finally, you need to select lithium-ion batteries based on the calculation results.
2. Prepare materials
Choose a reputable lithium-ion battery manufacturer and purchase polymer lithium-ion batteries with quality assurance; don't be tempted by cheap prices. After all, lithium-ion batteries are assembled, and if problems occur during assembly, they could pose a danger.
3. Specific steps for assembling lithium-ion batteries
First, arrange the lithium-ion batteries neatly, then use materials to secure each string of lithium-ion batteries. After securing each string of lithium-ion batteries, use insulating materials such as barley paper to separate each string of lithium-ion batteries to prevent damage to the battery casings that could lead to short circuits later.
After arranging and securing the batteries, the most crucial series connection step can be performed using nickel strips. Once this step is complete, only the final finishing touches remain. Bundle the lithium-ion batteries together with tape, and cover the positive and negative terminals with barley paper to prevent short circuits caused by errors in subsequent operations.
Precautions for polymer lithium-ion battery assembly
1. Aluminum-plastic composite film outer packaging protection: The most important thing is to prevent damage from sharp parts. To this end, polymer battery manufacturers should regularly clean the environment around the batteries, prevent sharp parts from touching or bumping the cells, and wear gloves when handling them to prevent fingernails from scratching the surface of the cells.
2. Top and side sealing edge maintenance: To prevent damage to the top and side sealing edges and impair the sealing effect, bending of the top and side sealing edges should be avoided; at the same time, the cell design must adopt reliable insulation isolation measures to prevent short circuit between the negative electrode and the aluminum-plastic composite film.
3. Terminal Protection: The positive terminal of the polymer lithium-ion battery cell uses an aluminum terminal, and the negative terminal uses a nickel terminal. Because the terminal is thin, bending should be avoided; at the same time, during the production process, the terminal should be prevented from contacting the aluminum-plastic composite film, and a protective film should be used to strictly isolate it.
4. Prevent mechanical impacts, such as falling, shocks, bending of the battery cells, and accidental damage to the battery.
5. Do not use metal objects or wires to short-circuit the positive and negative terminals.
In conclusion, whether polymer lithium-ion battery packs are used in our daily lives or in industrial fields, safety must be taken seriously. At the same time, the safety technology of lithium-ion battery packs must be continuously improved.
