(GB2129604-A)      An electrochemical cell comprises a metal housing (12) contg. an anode, a cathode and an electrolyte. The housing has an open end in the proximity of which the walls (14) are conical.    The novel feature is that the cell is sealed at the top by a metal cap (11) which has a conicity complementary and corresp. to that of the housing wall and has a tight fit with the wall.    The housing constitutes an electrical terminal for the anode or the cathode and the metal cap constitutes the electrical terminal for the other electrode. Between the conical wall of the housing and the conical wall of the metal cap is a thin sealing layer (15) held compressed by the tight fit of the cap.    For cells partic. of the non-aq. type the joint (15) is reliable and of low cost. It can also serve as a venting mechanism which can be abruptly or slowly operated.    (7pp)    (US4533609-A)      Electrochemical cell container comprises a metal-walled vessel having a tapered flattened cone-shaped top, with a circular indentation running round just below the top; fitted with an insulating sleeve and a corresp. shaped cap. The metal wall serves as the anode (or cathode) or is connected to the anode (or cathode); and the metallic cap is connected to the cathode (or anode respectively).    USE -   The container is esp. suitable for non-aqueous electrochemical cell systems.
