Core Advantages of Ceramic Electrolyte Pumps
- Ultra-High Precision Filling: Micro-liter and milli-liter level dosing with excellent repeatability ensures consistent electrolyte injection for every battery cell.
- Excellent Corrosion Resistance: Made of zirconia ceramic, the pump does not react with electrolyte and prevents contamination.
- Zero Leakage Sealing: Ceramic-to-ceramic mirror polishing provides perfect sealing performance, eliminating leakage and improving safety.
- Super Long Service Life: Wear-resistant ceramic materials ensure stable operation over 50 million cycles, reducing maintenance costs.
- No Metal Contamination: Inert ceramic materials prevent metal ion contamination, improving battery quality and yield.
- Custom Manufacturing Available: JuchangCeramic supports customization of flow rate, dimensions, and installation interfaces.
Working Principle
The lithium battery ceramic pump is driven by a servo motor or stepper motor. The ceramic plunger performs high-precision reciprocating motion inside the ceramic cylinder, changing the chamber volume to achieve accurate suction and discharge of electrolyte.
The extremely small clearance between ceramic components ensures strong sealing performance. Combined with a one-way valve system, the pump achieves stable, pulse-free, and leak-free fluid delivery.
This design guarantees high precision, consistency, and reliability, making it a critical component in lithium battery filling equipment.
