Marposs has acquired the Leak B-TRACER, a semi-automatic station designed for thorough leak testing of lithium-ion battery cells, in response to the increasing demand in the e-mobility market.

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.

Leak Detection for Unmatched Reliability

The Leak B-TRACER employs a special process to verify the sealing of batteries: Marposs has pioneered a groundbreaking electrolyte tracing technique for leak detection of several types of sealed battery cells during different operations of the assembly process, before or after formation and degassing. In the event of a leak, the Leak B-TRACER vaporises and extracts the solvent contained in the electrolyte recipe 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

·Rechecking 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 prioritises ease of use with a rapid retooling kit, ensuring minimal downtime during production line changeovers.

Marposs: Committed to the Future of E-Mobility

The Leak B-TRACER represents Marposs’ unwavering dedication to advancing e-mobility by providing innovative solutions that ensure battery safety and performance.
