Marposs to display EV battery solutions at The Battery Show India 2024 • EVreporter

Marposs is set to exhibit at Battery Show India 2024, presenting its cutting-edge solutions for EV battery manufacturers. Focusing on quality, safety, and efficiency, Marposs offers advanced technologies for various battery types.

Safety is a top priority in the EV battery industry, from coating and drying to calendering, slitting, separation, and assembly. Marposs technologies and products are designed to meet and redefine safety standards, creating a secure, advanced, and reliable process.

Basis Weight Measurement in EV Battery Production

The coating of battery electrode components, involving a roll-to-roll application of active material (slurry) onto a thin metal substrate, must ensure homogeneity and uniformity to prevent potential hazards. Thanks to its acquisition of MeSys, Marposs can provide precise measurements of coating basis weight, ensuring consistent battery production quality, using Ultrasonic basis weight sensors with patented technology.

Marposs technologies extend beyond basis weight measurement. Post-drying, electrodes undergo calendering to increase energy density by compressing the active material. Controlling deviations in thickness is critical, and Marposs utilizes chromatic confocal technology and camera inspections during this vital step.

At the Marposs booth, visitors can learn about Mesys Unisense, a single horizontal traversing scanning sensor available in C or O shapes. The first configuration is perfect for narrower applications. This Ultrasonic sensor scanner offers a simple yet accurate way to measure the basis weight of both wet and dry films in battery production. The second one is versatile and ideal for all web measurement applications.

Mesys Unisense GO is a portable version featuring a single sensor suitable for any environment. It is a versatile solution designed for integration into battery electrode production lines or laboratory settings. Its lightweight body provides immediate usability and can be easily detached and taken wherever needed, offering a convenient and versatile measurement experience without compromising performance.

LeakB-TRACER at The Battery Show

Leak B-TRACER is a revolutionary semi-automatic station designed for comprehensive leak testing of lithium-ion battery cells.

The EV 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.

Leak Detection for Unmatched Reliability

The Leak B-TRACER employs a special process to verify the sealing of batteries:

Marposs has pioneered an Electrolyte Tracing technique for leak detection of several types of sealed battery cells during different assembly process operations, before or after formation and degassing. In the event of a leak, the Leak B-TRACER vaporizes and extracts the solvent 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
• 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 and 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.
