Hermetic epoxy seals protect lithium ion batteries

Whether they take to the streets in electric vehicles or stand still in energy storage systems, lithium-based battery modules pose a tough challenge from a wire sealing standpoint. Modern battery modules have a variety of power and signal conductors running between their individual electrochemical cells and through the battery pack’s exterior casing.

 Increasingly, battery makers are looking to epoxy-based feedthroughs as an alternative to glass-to-metal seals. Epoxies have a unique balance of mechanical, electrical, thermal and chemical-resistance properties that make them a good fit for battery sealing applications.

Check out our latest paper to learn how to incorporate hermetic power and signal feedthroughs into modern battery modules.
