Hermeticity Testing

For medical batteries, hermeticity is a critical quality and safety requirement. Even microscopic leaks can affect battery performance, reliability, and ultimately the safety of the final medical device.

At Wyon, leak detection is an integral part of our quality strategy. Every battery design and production process is developed with a strong focus on maintaining the hermeticity of the cell throughout its entire lifecycle.

Beyond conventional testing methods, Wyon has developed an innovative leak detection approach in collaboration with TOFWERK. This technology enables the direct detection of electrolyte solvent emissions under ambient conditions, allowing highly sensitive and non-destructive testing of individual battery cells. The method provides quantitative and traceable results while supporting rapid testing suitable for production environments.
