The E-Mobility revolution is taking the world by storm, but its success depends on one crucial element: safe and reliable lithium-ion batteries. These powerful batteries propel electric vehicles, but they often contain flammable electrolytes that pose safety risk if they leak. Leaks can also lead to a rapid decline in battery performance, reducing driving range and overall efficiency.

Marposs, a company dedicated to innovation in manufacturing, has introduced a game-changing solution: the Leak B-TRACER. This revolutionary semi-automatic station offers comprehensive leak testing throughout the battery assembly process, ensuring the integrity and safety of every battery cell.

Double-Edged Sword: Uncompromising Leak Detection

The Leak B-TRACER takes a two-pronged approach to leak detection, guaranteeing unmatched reliability:

• Pre-filling Leak Detection: Before the battery cell is filled with electrolyte and sealed, the Leak B-TRACER leverages a tried-and-tested method – helium leak detection within a vacuum chamber. Here, the system introduces helium gas into the empty cell. A highly sensitive mass spectrometer then meticulously identifies and measures any leaks, ensuring the cell is in perfect condition before filling.
• Electrolyte Tracing – A Pioneering Post-Filling Inspection: Marposs doesn’t stop there. They’ve introduced a groundbreaking Electrolyte Tracing technique for leak detection after the cell is filled and sealed.  In the unfortunate event of a leak, the Leak B-TRACER vaporizes and extracts the electrolytes within the controlled environment of the vacuum chamber. A specially calibrated mass spectrometer then analyses the extracted vapor, quantifying the leak rate with exceptional precision. This vital information allows manufacturers to identify and address even the most minute leaks before defective batteries enter the production line.

Seamless Integration for Maximum Efficiency

Designed for seamless integration into existing production lines, the Leak B-TRACER offers a user-friendly, semi-automatic operation. Operators manually load the battery cells, and the system takes care of the rest with its automated testing cycle. This makes the Leak B-TRACER ideal for a variety of tasks, including:

• Prototype and pilot line testing: During the development phase of new battery designs, the Leak B-TRACER plays a vital role in ensuring the integrity of early prototypes.
• Random off-line testing and statistical process control (SPC) analysis: Manufacturers can perform regular quality checks throughout production runs using the Leak B-TRACER. This helps identify any potential issues in the assembly process and implement corrective measures to ensure consistent quality.
• Re-checking of scrap batches: Even the most advanced manufacturing processes can produce defective batches. The Leak B-TRACER allows for efficient re-checking of scrap batches, helping to salvage usable cells while identifying the root cause of the initial failure.

Unmatched Versatility: A Champion for Multiple Battery Applications

The Leak B-TRACER demonstrates exceptional versatility, accommodating various battery cell formats. Whether you’re working with button, cylindrical, prismatic, or pouch cells, the Leak B-TRACER can handle them all.  Furthermore, the system is adaptable for integration at different stages of the battery building process, including pre- and post-filling, as well as end-of-line testing. This flexibility makes it a valuable asset for any manufacturer producing lithium-ion batteries for a wide range of applications.

Fast Retooling and User-Friendly Design: Minimizing Downtime

Marposs prioritizes ease of use with the Leak B-TRACER. The system features a rapid retooling kit that ensures minimal downtime during production line changeovers. This allows manufacturers to quickly switch between different battery cell formats without sacrificing production efficiency.

Marposs: Pioneering a Safe and Sustainable E-Mobility Future

The Leak B-TRACER is a testament to Marposs’ unwavering dedication to advancing E-Mobility.  This innovative solution ensures battery safety and performance, paving the way for a more reliable and secure future for electric vehicles. By safeguarding battery integrity, the Leak B-TRACER fosters trust in E-Mobility technology, accelerating the transition towards a cleaner and more sustainable future.
