Precision Engineering for Extreme Conditions

When it comes to ensuring the performance and longevity of lithium batteries, the importance of battery end seal technology cannot be overstated. Complete Hermetics specializes in custom glass-to-metal sealing techniques engineered for maximum reliability in lithium battery seals. These seals are designed to endure harsh environments—extreme temperatures ranging from -40°C to over +150°C, high electrical currents, pressure changes, electrochemical corrosion, and moisture sensitivity.

Unmatched Quality in Battery End Feedthrough Seals

Battery end feedthrough seals serve critical roles in a variety of industries, including medical devices, communication systems, military applications, sensors, and the automotive sector. These hermetic products ensure that lithium batteries remain safe, functional, and long-lasting under the most demanding conditions. With each seal, Complete Hermetics conducts a rigorous 100% leak test with a minimum leak rate of 1×10⁻⁸ cc He/sec and offers optional high-voltage breakdown and electrical isolation tests to meet industry-specific needs.

How Hermetic Seals Enhance Lithium Battery Performance

A properly sealed battery end cover ensures optimal power delivery and extends battery life. Missing or damaged seals allow energy to escape, drastically shortening battery lifespan. The glass-to-metal sealing process used by Complete Hermetics requires precision temperature control and material compatibility to form a lasting, cohesive seal. The result is a barrier that resists power loss and blocks the ingress of moisture and contaminants.

Why Dependability Matters

For applications where failure is not an option—pacemakers, weapons systems, or aerospace components—durability and precision are paramount. As a leading battery end seal manufacturer, Complete Hermetics delivers consistently reliable solutions that meet the highest standards of quality and performance.
