An electrochemical generator is provided, more especially a cell or battery of the metal/air type, comprising a thin positive air electrode 1 forming cathode and having a shape such that it leaves available a space which it partially surrounds, a current collector 2 associated with this positive electrode, an anode mass 4 disposed inside this positive electrode in said available space, a second current collector 5 associated with this anode mass and possible a separator 6 between said anode mass and said positive electrode, characterized in that said positive electrode has the shape of a glove finger or bell.

Electrochemical generator of the metal/air type comprising: (a) a cylindrical container; (b) a thin positive air electrode constituting a cathode and being constituted by a slightly truncated conical portion, closed at its smaller diameter end by a substantially hemispherical cap portion, integral with said truncated cone portion, a solid cylindrical nipple crowning the hemispherical cap, said electrode being located inside said container at a certain distance from the internal surface of said container so as to leave a volume of air between said surface and the external surface of said electrode; (c) an anodic mass located inside said electrode, said mass occupying a substantial portion of the volume inside said electrode; (d) a first current collector associated with said electrode, said first current collector being constituted by a thin porous metallic film adhering on at least a part of the external surface of said electrode; (e) a second current collector associated with said anodic mass; and (f) a separator between said electrode and said anodic mass, said separator being applied against the internal surface of said electrode.
