    • An improved air cathode structure (10) for use in primary batteries and the like. The cathode structure includes a matrix active layer (11), a current collector grid (12) on one face of the matrix active layer, and a porous, nonelectrically conductive separator (15) on the opposite face of the matrix active layer, the collector grid and separator being permanently bonded to the matrix active layer. The separator has a preselected porosity providing low IR losses and high resistance to air flow through the matrix active layer to maintain high bubble pressure during operation of the battery. In the illustrated embodiment, the separator was formed of porous polypropylene. A thin hydrophobic film (16) is provided, in the preferred embodiment, on the current collecting metal grid.

    • An improved porous cathode structure (11) for use in a battery having a reactive metal electrode and flowed electrolyte. The cathode (10) is preferably formed of an electrically conducting porous material with categorically active surface (12) at an interface with the electrolyte. Alternatively the cathode (10) may be of an electrochemically reducible porous material and defines an active surface (12). Structure is provided for delivering electrochemically reducible cathode reactant material continuously through the cathode (10) to the cathode active surface (12) during operation of the battery. The reactant material is delivered in an amount required to be reduced at the active surface (12) to maintain high energy discharge rate with minimum amount of reactant material being utilized. The reactant material, in the illustrated embodiment, is provided from a storage supply (16) and delivered to the porous cathode (11) as needed during operation of the battery. In one form, the cathode (10) is provided with distribution passages (14) for conducting the reactant material therethrough. In another form, the reactant material is introduced through one or more edge portions of the cathode porous body (11) for flow through the pores to the active surface (12).
