Metrology for battery cells

Battery cells are at the heart of every high-voltage battery. Precise production and process monitoring is essential to ensure maximum safety, efficiency and service life. Mahr offers high-performance metrology solutions for this – both for monitoring individual production steps and for quality assurance on the finished product.

Typical tasks in cell and electrode production:

  • Tactile layer thickness detection
  • Monitoring the calendering process
  • Inline film measurement
  • Inspection of the cutting profile
  • Web edge control


Our systems solve the following tasks, for example:

  • Optical monitoring and control systems
  • Leak and high-voltage testing
  • Production monitoring of relevant individual components such as battery frames, connectors and structural components

Metrology for battery modules and packs

A battery module, in turn, is a highly complex assembly within the high-voltage battery. The assembly process places the highest demands on precision, cleanliness, insulation, heat dissipation and process stability. Mahr supports manufacturers here specifically in the end-of-line area with the appropriate metrology.
