Hermetic Sealing Solutions for High-Performance Miniaturized Battery Systems
by Master Bond from IEEE Spectrum on (#72CP3)

Achieve reliable hermetic sealing for millimeter-scale microbatteries using dual-seal epoxy adhesive methods that maximize energy density while preventing electrolyte leakage and moisture ingress.
What Attendees will Learn
- Seal smart, not complex" -- Dual-seal approach combines epoxy adhesives with gaskets for optimal hermeticity.
- 2mm breakthrough -- Successfully demonstrated microbatteries operating at 120C with 22-hour continuous performance.
- Energy density maximized -- Surface-area-to-volume optimization maintains high Wh/L and Wh/kg ratios.
- Proven materials -- Epoxy adhesives with Kapton/neoprene gaskets deliver chemical resistance and low permeability.
