More Information

Microbatteries face unique challenges in hermetic sealing due to their millimeter-scale dimensions. As battery size decreases, the surface-area-to-volume ratio increases, making traditional sealing methods like laser welding impractical. This guide explores innovative dual-seal methods using epoxy adhesives combined with laser-cut gasket materials to achieve hermetic integrity while maximizing energy density. The approach addresses critical requirements including chemical resistance to electrolytes, low permeability to moisture, and thermal stability across operating temperatures.
