Title: Feedthrough terminal for high-power cell

Abstract

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 is enclosed in a stainless steel tube with a BN powder feedthrough seal maintained around the stainless steel tube by means of facing insulative bushings and an outer sleeve. One end of the copper conductor is silver-brazed directly to a flat, butterfly bus bar 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.

  • A double sealed technique in an evacuated quartz jacket produces an electrical feedthrough assembly suitable for use in sealed-off , pulse, longitudinal discharge lasers compatible with operating temperatures of up to 1100/sup 0/ C without oxidation and with a minimum of circuit inductance.
  • Multiterminal, high voltage dc power networks is disclosed in which the sub-terminals are electrically isolated from each other comprise dc transformers, as the terminals. Each transformer comprises a large number of efficient, high energy batteries, connected as two separate groups: one group made up of paralleled long strings of series connected batteries and the other group made up of paralleled short strings of one or more batteries each. Each transformer also comprises automatic monitoring, control and switching means for periodically exchanging charged and discharged strings between the two groups, one of which-the ''primary''-is connected across the supply lines from themore » power source(s) for the network and the other of which-the ''secondary''-is connected across the service lines providing power to users thereof.« less
