1. Anode assembly for use in a fused bath electrolysis aluminum production cell, comprising:

  • an inert anode in the shape of a ladle, with length L, and comprising a cavity, an open end comprising an opening, a wall surrounding the cavity, a closed end and at least one means for mechanically connecting the inert anode to a connection conductor;

    a connection conductor comprising a connection end and means for mechanically connecting the connection conductor to the inert anode, and capable of cooperating with the means for mechanically connecting of the inert anode, so as to create a mechanical linkage between the conductor and the inert anode; and

    at least one brazed metallic joint or at least one brazing material that can form a brazed metallic joint by brazing wholly or partly during use, the joint or the material being disposed directly between the conductor and the anode, at at least part of at least one anode connection surface at the open end of the inert anode, and at least part of at least one conductor connection surface at the connection end of the conductor.
