In response to the growing demands of the E-Mobility market, Marposs is proud to own the Leak B-TRACER, a revolutionary semi-automatic station designed for comprehensive leak testing of lithium-ion battery cells.
Ensuring Safety and Performance in Next-Generation Batteries
The E-Mobility revolution depends on the safety and reliability of lithium-ion batteries, a cornerstone technology in electric vehicles. These batteries often contain electrolytes with flammable components that can pose safety risks if compromised. Leakage can also lead to performance degradation. The Leak B-TRACER addresses these concerns by offering leak detection throughout the battery assembly process.
Two-Step Leak Detection for Unmatched Reliability
The Leak B-TRACER employs a two-step process to guarantee the integrity of battery cell seals.
Pre-filling Leak Detection:
Before electrolyte filling and sealing, the Leak B-TRACER utilizes a proven helium leak detection method within a vacuum chamber. Helium gas is introduced into the empty cell, and a mass spectrometer precisely identifies and measures any leaks.
Electrolyte Tracing for Post-Filling Inspection:
Marposs has pioneered a groundbreaking Electrolyte Tracing technique for leak detection after electrolyte filling and sealing. In the event of a leak, the Leak B-TRACER vaporizes and extracts the electrolytes within the vacuum chamber, allowing a specially calibrated mass spectrometer to quantify the leak rate.
Flexibility and Efficiency for Seamless Integration
The Leak B-TRACER is designed for seamless integration into existing production lines. This user-friendly, semi-automatic station features manual loading with an automated testing cycle, making it ideal for:
- Prototype and pilot line testing
- Random off-line testing and statistical process control (SPC) analysis
- Re-checking of scrap batches
- Unmatched Versatility for Diverse Battery Applications
The Leak B-TRACER offers unparalleled versatility, accommodating various battery cell formats (button, cylindrical, prismatic, or pouch) and electrolyte types (DMC, EMC, PP, etc.). Furthermore, the system is adaptable for integration at different stages of the battery building process, including pre-and post-formation, as well as end-of-line testing.
Fast Retooling and Easy Use
The Leak B-TRACER prioritizes ease of use with a rapid retooling kit, ensuring minimal downtime during production line changeovers.
