Abstract: A lid assembly for an electrochemical cell comprises a plate-shaped lid having an opening and a glass-to-metal seal (GTMS) residing in the lid opening. The GTMS does not have a ferrule. Instead, the GTMS has a sealing glass that seals directly to a terminal pin and to the lid. The terminal pin has an enlarged diameter pin section contacted by the sealing glass and a first reduced diameter pin section extending axially outwardly from the enlarged diameter pin section. An electrochemical cell provided with the lid assembly is also described.
