Three silver lithium-ion batteries and capacitors

Battery and Capacitor Lids

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.

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.

Product variants

SCHOTT offers GTMS lid systems in standard or customized geometries for cylindrical and prismatic cell designs. To provide optimal housings for lithium batteries and capacitors operating in a broad range of conditions, our hermetically sealed lids are made of robust metals such as steel, stainless steel, or aluminum, all matched with specialty glass.
