Battery Lids and Connectors

Reliability-critical battery and capacitor applications require rugged, long-lasting packaging designs. Offering durable hermetic protection, glass-to-metal sealing (GTMS) is the technology of choice for lithium primary and industrial-grade lithium-ion battery lids, as well as gas-tight caps for aluminum electrolyte capacitors and ultracapacitors.

SCHOTT GTAS® lids for cylindrical battery cells for added battery capacity

Eliminating moisture intrusion and electrolyte leakage

SCHOTT Battery and Capacitor Lids are designed to eliminate moisture intrusion and electrolyte dry-out by using an inorganic, non-aging glass seal. Organic polymer and rubber versions are prone to aging in harsh conditions. As a specialty glass expert, we offer customized battery and capacitor GTMS to fit with different electrolytes and/or specific application requirements.

Simple and rugged for more economical battery designs

Inorganic and robust glass-to-metal or aluminum lid designs allow battery developers to reduce the number of parts needed. This enables a simplified lid construction, potentially even reducing the number of components used for the battery pack as a whole by bringing reliable, long-term hermeticity to the cell level.
