Abstract: A reticulate primary electrode, usually cathode, and method for making for use in an electrochemical cell. The cathode is openly porous, in substantial physical contact with a separator used in the cell for separating anode and cathode compartment within the cell, and intermetallically bound to a cathodic current collector used within the cell.

Abstract: A self-supporting reticulate of titanium hydride (TiH.sub.2) is formed by slurry-coating an open cell organic synthetic resinous material, or other pore-former, and eliminating the carbon-containing components of binder and/or solvent, viscosity modifiers, thickening agents, and the like at a temperature below about 400.degree. C. In an analogous manner, an inorganic refractory material open cell substrate or other pore-former substrate may be slurry-coated and converted to a TiH.sub.2 reticulate in which the substrate is coated with TiH.sub.2 to yield a supported TiH.sub.2 reticulate. Either the self-supporting TiH.sub.2 reticulate, or the supported one, free of carbonaceous material, may be sintered to yield an essentially pure Ti (metal) reticulate which is essentially free of titanium carbide. Ti reticulates so formed are coated with Pt group metal oxides and used as anodes in chloroalkali cells.

Abstract: A battery structure using a plurality of cells in stacked array wherein each cell comprises an anode having a centrally positioned opening and flange positioned about the periphery of the opening for contact with the periphery of the opening of an adjacent anode. Each cell includes a pelletized depolarizer material that extends beyond the perimeter of the anode but coextensive with the anode flange. An outer encasement member receives the stacked array so that the depolarizer pellets are in electrical contact with the inner surface of the encasement. The encasement means includes a top member having an opening located to align with the openings in the anode and anode collector positioned through said opening in the top member and electrically insulated therefrom and in electrical contact with each of said anode flanges.

Abstract: The present invention relates to a depolarizer for use in a lithium halide battery which comprises a halogen and a charge transfer complex consisting of the halogen and an organic component of (a) quaternary amine halide selected from the group consisting of (i) polyvinylalkylpyridinium halide or polyvinylalkylquinolinium halide and (ii) poly [N,N'-dialkyl 1,2 bis (4-pyridinium halide)] ethylene or poly [N-alkyl 1,2 bis (4-pyridinium halide) ethylene] and (b) phenyl methane dyes wherein said halogen is present in an amount of from about 3 to 50 parts by weight for each part of organic component.

Abstract: The present invention relates to a lithium halide battery structure comprising an outer metal envelope and top portion which is hermetically sealed to the envelope. The top portion includes an insulator conforming to and positioned thereon to the base configuration of the top portion and a support means having a base configuration substantially the same as the insulator. The support means also includes a flange depending from the support base and a pair of spaced apart post holders integral with said flange. First and second posts are positioned in the post holders with a metal anode collector screen positioned between and attached to said posts. The first post extends through the support means, insulator and top portion to define the anode terminal. The second post terminates in the associated post holder. A first and second pair of lithium anodes are pressure bonded together to sandwich therebetween the support means and anode collector screen.
