Abstract
The disclosure provides seals for devices that operate at elevated temperatures and have reactive metal vapors, such as lithium, sodium or magnesium. In some examples, such devices include energy storage devices that may be used within an electrical power grid or as part of a standalone system. The energy storage devices may be charged from an electricity production source for later discharge, such as when there is a demand for electrical energy consumption.
Claims17
An electrochemical cell, comprising:
- a container comprising a conductor aperture, wherein said container is configured to contain a reactive material at a temperature of at least about 200 C;
- a conductor that extends through said conductor aperture;
- and
- a sealing unit that couples said container to said conductor to seal said conductor aperture, wherein said sealing unit comprises a first ceramic component, a second ceramic component, a third ceramic component, a first metal sleeve, and a second metal sleeve that are configured to be exposed to said reactive material while sealing said conductor aperture, wherein said first metal sleeve is disposed between said first ceramic component and said second ceramic component, wherein said second metal sleeve is disposed between said second ceramic component and said third ceramic component, wherein said second ceramic component electrically isolates said first metal sleeve from said second metal sleeve, and wherein (i) said first metal sleeve is coupled to said container and (ii) said second metal sleeve is coupled to said conductor.
