A feedthrough terminal for a high power electrochemical storage cell providing low resistance coupling to the conductive elements therein while isolating the terminal electrode from the highly corrosive environment within the cell is disclosed. A large diameter, cylindrical copper electrode 40 is enclosed in a stainless steel tube 42 with a BN powder feedthrough seal 52 maintained around the stainless steel tube by means of facing insulative bushings 50A,50B and an outer sleeve 48. One end of the copper conductor is silver-brazed directly to a flat, "butterfly" bus bar 18 within the cell, with the adjacent end of the surrounding outer feedthrough sleeve welded to the bus bar. A threaded seal is fixedly positioned on a distal portion of the stainless steel tube immediately adjacent the distal insulative bushing so as to compress the feedthrough seal in tight fitting relation around the stainless steel tube in providing a rugged, leak-proof electrical feedthrough terminal for the power cell. <IMAGE> |
