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.
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.
Hermetically sealed lids for years of reliable performance
SCHOTT lid systems are designed to provide dependable protection for lithium batteries and aluminum electrolyte capacitors and ultracapacitors for their entire lifetime, in many cases up to 20 years. Chemical stability, high temperature resistance, and autoclavability are further reasons why leading customers all over the world rely on these state-of-the-art battery and capacitor housings from SCHOTT.
