    摘要： Composite current collectors containing coatings of metals, alloys or compounds, selected from the group of Zn, Cd, Hg, Ga, In, Tl, Sn, Pb, As, Sb, Bi and Se on non-metallic, non-conductive or poorly-conductive substrates are disclosed. The composite current collectors can be used in electrochemical cells particularly sealed cells requiring a long storage life. Selected metals, metal alloys or metal compounds are applied to polymer or ceramic substrates by vacuum deposition techniques, extrusion, conductive paints (dispersed as particles in a suitable paint), electroless deposition, cementation; or after suitable metallization by galvanic means (electrodeposition or electrophoresis). Metal compound coatings are reduced to their respective metals by chemical or galvanic means. The current collectors described are particular suitable for use in sealed primary or rechargeable galvanic cells containing mercury-fee and lead-free alkaline zinc electrodes.

    摘要： A process for enhancing chemical stability and corrosion resistance is described for perforated current collectors made by continuous production processes for use in electrochemical cells, including storage batteries such as lead-acid batteries. The process relies on utilizing a strip processing method, selected from the group of reciprocating expansion, rotary expansion and punching, to perforate the solid metal strip to form a grid or mesh, as a deformation treatment. The perforation-deformation treatment is followed in rapid succession by a heat-treatment to obtain a recrystallized microstructure in the current collector and optionally by quenching to rapidly reduce the temperature to below approximately 80° C. The process yields an improved microstructure consisting of a high frequency of special low &Sgr; CSL grain boundaries (>50%), exhibiting significantly improved resistance to intergranular corrosion and cracking. Perforated current collectors produced with this process from a solid lead-alloy strip exhibit superior growth and corrosion properties when employed as positive grids in a lead-acid battery.

    摘要： A test cell structure for fuel cell or electrochemical cell technology is disclosed. Principally, the test cell may be used for testing gas diffusion or solid electrodes in a controlled environment, and such other matters as quality assurance tests of fuel cell components including electrodes, electrolytes, etc. In a simple embodiment, the test cell includes a body having an electrolyte chamber extending from one side to the other, and an electrolyte reservoir above. reactant fluid (usually gas) chambers are formed in blocks that are secured to each side of the body, so that the gas chambers face the electrolyte chamber; and means are provided to conduct gas to and away from each of the gas chambers. Electrodes are mounted in interposed relation between the electrolyte chamber and the gas chambers at each side thereof, where the electrodes are mounted in a separable frame which, when in place, provides a fluidtight seal between the body and each of the respective gas chambers. in a preferred embodiment, a well is formed integrally with the body as the electrolyt reservoir, having a liquid conduit communicating to the electrolyte chamber. A gas lift pump is provided for electrolyte circulation, and to provide an inert atmosphere over the electrolye, if required. A heat exchanger may be placed into the well so as to control the operating temperature of the electrolyte.

    摘要： Anode applicators include consumable anodes, that can be operated in a non-stationary mode and are insensitive to orientation, are used in selective plating/brush electrodeposition of coatings or free-standing components. The flow-through dimensionally-stable, consumable anodes employed are perforated/porous to provide relatively unimpeded electrolyte flow and operate at low enough electrochemical potentials to provide for anodic metal/alloy dissolution avoiding undesired anodic reactions. The consumable anodes include consumable anode material(s) in high surface area to reduce the local anodic current density. During electroplating, sufficient electrolyte is pumped through the consumable anodes at sufficient flow rates to minimize concentration gradient and/or avoid the generation of chlorine and/or oxygen gas and/or undesired reaction such as the anodic oxidation of P-bearing ions in the electrolyte. The active consumable anode material(s) can have a microstructure which is fine-grained and/or amorphous to ensure a uniform anodic dissolution.
