Battery and Capacitor Lids
Lithium Primary Battery Covers
SCHOTT´s hermetically sealed battery covers enable the long-lasting performance of lithium primary batteries, even in harsh environment applications.
- Availability of standard sizes from AA, to C and D Cells.
- Customized designs (cylindrical and prismatic).
- High temperature resistance, ranging from -85°F to more than +302°F.
- Proprietary electrolyte-resistant glass specially developed for lithium primary chemistries, including lithium thionyl chloride (Li-SOCL2), Lithium Manganese Dioxide (LiMO2), Lithium Sulfur Dioxide (LiSO2), and more.
- Hermetic sealing reliably prevents humidity intrusion into the cell housing and electrolyte leakage.
SCHOTT battery covers are trusted by the battery industry worldwide with a proven lifetime of up to 25 years or more.
Thermal Battery Covers
Thermal batteries are primary components that employ an internal heat source to bring a battery stack to operating temperature when required. This is often on a moment’s notice after a long period of non-use.
SCHOTT manufactures thermal battery covers that provide unparalleled protection using glass-to-metal sealing technology for decades. These components are engineered to support the long-term uncompromised reliability of thermal battery assemblies.
YOUR ADVANTAGES
- Hermetically sealed for maximum protection.
- Resistant to corrosives, such as lithium and lithium thionyl chloride.
- Made to exact build-to-print customer specifications, with experience in supporting defense applications.
Lithium-Ion Battery Lids
SCHOTT’s battery covers are available in glass-sealed stainless steel or glass-to-aluminium-sealed (SCHOTT GTAS®) designs.
- Simplified, rugged lid design.
- High-temperature resistance, ranging from -76°F to more than +302°F, depending on design.
- Proprietary, electrolyte-resistant glass-sealing, especially developed for a wide range of lithium ion battery chemistries.
- Non-aging, fully hermetic design prevents humidity intrusion into the cell housing.
- Lifetime of up to 25 years.
Ultracapacitor Lids
SCHOTT´s glass-to-aluminum-sealed (SCHOTT GTAS®) ultracapacitor lid systems offer:
- High-temperature resistance, ranging from -40°F to more than +257°F.
- Electrolyte-resistant, non-aging glass seals that eliminate electrolyte dry-out.
- Up to 20% reduction in electrolyte volume.
- Reduction of capacity losses over time by up to 60%.
- Improvement of internal resistance by over 50%.
Ultracapacitors are now applied for larger-scale usage such as electric vehicles that rely on these components as they have far greater charge storage areas than standard capacitors.
High-power and renewable-energy applications also utilize ultracapacitors. These applications have pushed the demand for powerful, lightweight components that require little or no maintenance, are able to operate in harsh environments across a wide range of operating temperatures, and have high-power density and high reliability. SCHOTTs hermetic covers enable new ultracapacitor designs that push the boundaries of innovation even further.
Aluminum Electrolyte Capacitor Covers
SCHOTT´s glass-to-aluminum-sealed (SCHOTT GTAS®) caps for aluminium electrolyte capacitors offer:
- High-temperature resistance, ranging from -40°F to more than +257°F.
- Electrolyte-resistant, non-aging glass seals that eliminate electrolyte dry-out.
- Up to 20% reduction in electrolyte volume.
- Reduction of capacity losses over time by up to 60%.
- Improvement of internal resistance by over 50%.
Making use of these features, capacitor developers can design smaller capacitors with long operating lives, even for applications with high temperature ranges.
