High incremental track with constant current metering pump to improve injection accuracy
Date: 2023-09-04Read: 3
In the process of rapidly entering the TWh era in the lithium battery industry, the demand for scale development continues to drive technological innovation, leading to the growth of a large number of high-speed segmented tracks in the front, middle, and rear stages of the lithium battery process.
Injecting liquid is one of the core components of the mid stage I sequence, which has maintained rapid market growth in recent years. The injection process has gone through technological iterations such as atmospheric pressure injection, negative pressure injection, and isobaric injection. The infiltration speed of the electrode is constantly improving, which helps to increase the production efficiency of the injection process.
We need efficiency and yield. The ppb level defect rate requirement for extreme manufacturing in the "T era" concerns every detail in the lithium battery process.
For injection workers, achieving extreme manufacturing still faces many pain points such as low precision in injection volume and long injection time. The demand for liquid injection without batteries has become increasingly differentiated. This all points the finger at the injection pump, which is the core component of the injection system.
In response to this, Guangzhou Feisheng has launched the Constant Current Meter series, which can meet the needs of different battery types and I process types, providing safe, efficient, and more accurate injection processes for lithium batteries.
FSH-CF10 Constant Flow Meter Pump System
At present, the industrialization of large cylindrical batteries is imminent. Compared to square batteries, cylindrical batteries require a higher level of precision in liquid injection. In this regard, the FSH-CF10 constant current metering pump system has a repeated injection accuracy of 0.1%, which has passed the standard CE certification and is suitable for high-precision injection scenarios including 32 series and 46 series batteries.
FSH-CF22 constant current meter pump system
The FSH-CF22 constant current meter pump system adopts constant current metering technology, which can accurately control the injection flow rate and provide precise variable replenishment at any position to ensure stable and reliable injection process. It has passed the CE&ATEX standard explosion-proof&EMC&MD certification and is widely used in fields such as power battery and energy storage battery injection.
FSH-CF30 Explosion proof Constant Current Meter Pump System
The FSH-CF30 explosion-proof constant current metering pump system has a liquid injection efficiency of 40ml/s and a repeatability accuracy of 0.3%.
It is worth mentioning that in the era of lithium battery industry going global, the compliance importance of core components in overseas markets has become increasingly prominent. UL/ATEX explosion-proof certification is the operating threshold for injection pumps overseas.
For the North American market, the FSH-CF30-NA-E-P explosion-proof constant current meter pump system has passed UL explosion-proof certification; For the European market, the FSH-CF30-EU-E explosion-proof constant current meter pump system has passed ATEX explosion-proof certification.
FSH-CF150 Explosion proof Constant Current Metering Pump System
Energy storage batteries weighing over 800g are more concerned about the efficiency of liquid injection and standard explosion-proof certification. The FSH-CF 150 constant current meter pump system has a liquid injection efficiency of up to 120ml/s and has passed the CE&ATEX standard explosion-proof&EMC&MD certification, ensuring efficient and safe liquid injection for energy storage batteries.
In addition to addressing pain points in multiple application scenarios, the FSH-CF constant current meter pump adopts a new fully enclosed chamber, which avoids the formation of crystals and pump jamming caused by electrolyte contact with air.
In addition, the FSH-CF constant current meter pump adopts precision servo drive, which can achieve digital setting, modify the injection volume, realize intelligent closed-loop control, greatly improve the CPK value, enhance the consistency and stability of injection, and ensure the yield of injection process.
As of now, Guangzhou Feisheng has served the vast majority of China's top 30 lithium battery customers and exported to overseas markets such as Japan, South Korea, China, the United Kingdom, and Germany. Its FSH-CF constant current pump has been used in over 5000 lithium battery injection applications in China, and has obtained long-term batch verification and recognition on the production line.
