Galvanic element in form of a button cell and a procedure for the production of a galvanic element

An electrochemical element in the form of a button cell comprises lithium-intercalating electrode(s) and a housing with an opening (8). The opening is closed in a sealed manner during formation of the electrochemical element, opened once after formation for gas to escape from inside of the electroch...

Beschreibung
Zusammenfassung:	An electrochemical element in the form of a button cell comprises lithium-intercalating electrode(s) and a housing with an opening (8). The opening is closed in a sealed manner during formation of the electrochemical element, opened once after formation for gas to escape from inside of the electrochemical element, and then closed in a gastight manner. An independent claim is included for a method for producing an electrochemical element in the form of a button cell, comprising placing lithium-intercalating electrode(s) in a housing having an opening; sealing the opening during formation of the electrochemical element; breaking open the opening once formation of the electrochemical element has been completed for gas to escape from inside the electrochemical element; and closing the opening in a gastight manner.
