Abstract (en)

[origin: WO2022243716A1] This cover assembly for a secondary electrochemical cell comprises a cover plate (36), a negative terminal (16), a positive terminal (18). The negative terminal or the positive terminal comprises a terminal assembly (40), which comprises a terminal plate (50) adapted to be brought in contact with a connector; a terminal base (52) adapted to be electrically connected to a collector of the electrochemical cell; and a fuse (54) adapted to melt when subject to a determined rated electrical current and/or a determined rated electrical voltage. The fuse provides in the unmelted state an electrical connection of the terminal plate with the terminal base. The fuse (54) is adapted to, when melting, electrically separate the terminal plate from the terminal base and, upon melting, becoming molten fuse material. The terminal assembly comprises a fuse cavity (80) adapted to receive the molten fuse material.
