1. Battery filling method?
Use manual filling machine or automatic filling machine for filling operation.
2. How to check whether the battery is filled with electrolyte?
Use vacuum suction test. When vacuum suction is applied to the filling port, if electrolyte is drawn up, it means it is full, and if not, it means it is not full.
3. What is the role of LiOF6 in the electrolyte?
Conductive electrolyte.
4. Concentration of LiPF6 in the electrolyte?
1mol/L
5. What is the role of solvent in the electrolyte?
Dissolve electrolyte and ionize electrolyte.
6. Conductivity range of electrolyte?
8×10-3Ω-1
7. What is the effect of conductivity on battery operating current?
Conductivity affects rate discharge rate, internal resistance of battery, and voltage of battery.
8. What factors affect the internal resistance of battery?
Conductivity of electrolyte, performance of battery shell material, conductivity of pole piece and cross-sectional area of pole ear material. Quality of battery welding.
9. What factors affect the capacity of the battery?
The characteristics of the positive and negative electrode materials, the type, model and amount of active substances.
The correct ratio of the positive and negative active substances.
The concentration and type of the electrolyte.
The production process.
10. How do you think the water content in the battery can be controlled during the production process?
Strictly control the humidity of the environment and strengthen the baking of the battery cells to control the water content of the battery during the production process.
11. Can the resistance of the battery be measured with a meter when it is charged?
Yes
12. What should the formation machine pay attention to when forming a large-capacity battery?
Pay attention to whether the total power of the battery exceeds the power of the formation machine.
When customizing ultra-large power lithium batteries, you will often encounter some special codes, such as 24400, 48100 and 72280. These codes represent different battery specifications and performances, and have important guiding significance for the production and use of customized ultra-large power lithium batteries. Below we will introduce the meaning and application scenarios of these codes in detail.
