Marposs offers a comprehensive range of standard products and customized applications, in order to guarantee the best performing battery systems. 

This includes leak testing at various stages, from checking the sealing on the cell housing to the testing of the finished battery cell. The quality control extends to components of the battery pack, such as trays, frames, and covers, as well as the refrigeration circuit, covering chillers and cooling plates.
Our portfolio spans from in-line (IL) process control during cell assembly to complete end-of-line (EoL) checks and product validation after formation and aging. This comprehensive approach by Marposs guarantees the highest standards in the production of battery systems. 
We develop in-line quality control solutions for the roll-to-roll (R2R) production of electrode foils (cathode and anode) used in lithium-ion batteries (LIB). These solutions integrate various non-contact measurement and inspection technologies.

Marposs presents a variety of solutions throughout the manufacturing process for both pre-production pilot lines and mass production. 
In the roll-to-roll (R2R) production process of electrode foils for lithium-ion batteries (LIB), Marposs employs non-contact gauging and inspection technologies. 
Ahead of cell sealing, several applications for leak testing of various battery cell types with helium as a tracer gas are available. Instead, our innovative electrolyte tracing method allows testing sealed battery cells. 
For the End-Of-Line phase, Marposs provides dedicated solutions for electrical testing of all battery cell types.

Marposs designs leak testing machines using helium as a tracer gas in an accumulation chamber or vacuum chamber for testing both modules and fully assembled battery packs. Additionally, a comprehensive range of electronics based on air testing methods is available.
Marposs provides modular solutions dedicated to functional control at the end of the line in the assembly of modules and packs, in compliance with the most stringent safety and quality standards for the automotive market.
