In today’s high-performance energy applications, maintaining reliability under extreme conditions is critical. This is where hermetic products come into play—especially in lithium battery systems. These systems depend on tight, durable glass to metal seals and ceramic to metal seals to protect against environmental threats like moisture, pressure changes, and chemical reactions. Without a robust seal, the risk of failure, leakage, or degradation increases dramatically, affecting both performance and safety.

Precision Engineering for Demanding Applications

Whether it’s for medical, military, aerospace, or automotive use, hermetic connectors and custom hermetic feedthroughs must deliver uncompromising performance. Leading the charge is Complete Hermetics, a trusted hermetic seal manufacturer known for their innovation and consistency. Their solutions are engineered to perform in temperature extremes from -40°C to +150°C and provide exceptional resistance to corrosive agents, high voltages, and physical stress.

Each hermetic header and feedthrough is customized using high-grade materials such as stainless steel, alloy 52, and titanium. Paired with top-performing glasses like Corning 9010 and TA23, these materials ensure maximum sealing integrity. Every unit is helium leak-tested to a sensitivity of 1×10⁻⁸ cc He/sec, with optional electrical isolation and breakdown voltage testing.

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.
