    摘要： A rechargeable manganese dioxide/zinc cell is provided, where the cell has high capacity, high volumetric and gravimetric energy densities, high cycle life, and is capable of continued charge-discharge cycles following an overdischarge. The cell has an aqueous electrolyte, with the usual solute of potassium hydroxide, but the solute may also be a mixture of zinc chloride and ammonium chloride. The electrode balance as determined by the ration of the theoretical discharge capacity of the zinc and the theoretical one electron discharge capacity of the manganese dioxide ranges from greater than 65% up to 110%. On the 15th discharge, a cell of the present invention will deliver a discharge capacity of at least 20% of the discharge capacity delivered on the first discharge. A cell according to the present invention is capable of continued charge-discharge cycles after overdischarge or voltage reversal.

    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.

    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.
