Battery and Capacitor Lids

Glass-to-metal sealing has proven to be a highly reliable technology for producing battery and capacitor covers capable of withstanding extreme temperature, electrical current, pressure variations, and corrosive chemicals. SCHOTT glass-to-metal sealed lids can be designed to suit specific requirements, such as humidity-sensitive battery chemistry, corrosive capacitor electrolytes, and high electrical currents. The versatility and durability of glass-to-metal seals make them ideal for a wide range of lithium batteries, capacitors, and ultracapacitors.

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 -65°C to more than +150°C. 
  • 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 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.

SCHOTT´s glass-to-aluminum-sealed (SCHOTT GTAS®) ultracapacitor lid systems offer:

  • High-temperature resistance, ranging from -40°C to more than +125°C. 
  • 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.

SCHOTT´s glass-to-aluminum-sealed (SCHOTT GTAS®) caps for aluminium electrolyte capacitors offer:

  • High-temperature resistance, ranging from -40°C to more than +125°C.
  • 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.
