LITHIUM-ION BATTERY SEAL

摘要

A hermetic seal that is compatible with lithium-ion electrolyte in lithium batteries is formed in feedthroughs by compression, chemical bonding, and mechanical bonding between the metal pin and a sealing glass, such as Cabal-12. The pin is alternately coated with a metal or a metal oxide to enhance compatibility with the lithium battery environment. The pin surface is deformed to enhance bonding with the glass seal. Mechanical bonds are also achieved by placing the pin/glass seal interface in compression by a compression bushing.
