High-Precision, Corrosion-Resistant, Zero-Contamination Key Equipment for Lithium Battery Manufacturing
I. Core Advantages
1. Extreme Corrosion Resistance
Lithium battery production involves numerous corrosive media:
- Electrolyte: Contains fluorinated compounds such as LiPF₆ and LiFSI with strong corrosive properties
- Organic Solvents: Including NMP (N-Methyl-2-pyrrolidone), carbonate-based solvents
- Acid/Base Solutions: Chemical reagents used in electrode material preparation
Corstarfluid ceramic plunger pumps utilize specialized industrial ceramic materials such as zirconia, alumina, and silicon nitride, offering excellent chemical stability. Practical cases demonstrate that boron nitride plungers in lithium battery electrolyte filling pumps operated continuously for 2 years without corrosion signs.
2. Superior Wear Resistance
Lithium battery slurry contains substantial solid particles (lithium iron phosphate, ternary materials, carbon nanotubes, etc.), causing severe wear on traditional metal pumps. Ceramic plungers feature high hardness (Mohs hardness 9), with wear resistance 5-10 times superior to metal plungers.
3. Zero Metal Contamination
Ceramic materials are 100% inorganic, eliminating metal ion contamination and preventing iron, copper, zinc, and other foreign metal particles from entering the slurry, ensuring battery purity and performance. Compliant with FDA certification requirements, with non-porous surfaces that do not adsorb impurities.
4. High-Precision Metering
Flow accuracy reaches ±0.1%~±3%, with pulseless continuous delivery ensuring coating thickness uniformity, contributing to improved battery consistency and yield rates.
5. Long Service Life & Low Maintenance Costs
- Maintenance costs reduced by 80%
- Minimized downtime and production interruption risks
- No frequent replacement of seals and lubricants required
II. Primary Application Scenarios
| Application Scenario | Specific Process | Technical Advantages |
