摘要： For making battery electrodes, a composite strip of a cast ribbon of an electrically conductive metal attached to and extending along an edge of a web of electrically conductive carbon fiber material, also called a carbon felt in some examples, with a plurality of spaced apart notches cast in the ribbon and opening to an edge of the ribbon spaced from the carbon fiber material. A rotatable drum with a mold cavity and a confronting casting shoe for supplying molten metal, such as liquid lead, to the cavity may be used in a casting machine to continuous cast the composite strip.

摘要： The present disclosure is directed to bi-polar plates for use in lead-acid batteries, and methods of making the same. The bi-polar plates of the present disclosure comprise first and second conductive plates of lead joined by a plurality of connections through a plastic substrate. The connections may be formed by welding or in the process of casting the conductive plates, resulting in connections that are chemically homogenous with the conductive plates themselves. In addition, the welding and casting processes of the present disclosure offer significant time savings in the production of bi-polar plates.

摘要： A method of making a grid for a battery plate of a lead-acid battery. A substantially planar web is manufactured to include a plurality of spaced apart and interconnected wire segments, which at least partially define substantially planar surfaces, have a plurality of transverse lands, and interconnect at a plurality of nodes to define a plurality of open spaces between the wire segments. The web is reformed to change the cross-sectional shape of the wire segments. Other aspects may include simultaneously reducing the thickness of at least a portion of the web while reshaping the wire segments, and/or providing a controlled surface roughness on at least one of the surfaces of the web to increase surface area of the grid and thereby promote adhesion of an electrochemically active material to the grid.

摘要： A method of forming an electrode includes casting a molten metal in a mold to form an electrode with a header portion and a blade portion. The blade portion of the electrode is then rolled after it has been cast. The blade portion may be rolled into at least two different thicknesses. In one embodiment the metal is lead or lead alloy and the method relates to the forming of a lead or lead alloy anode.

摘要： The present invention provides a process for producing a grid for use in lead acid batteries which comprises superposing, on a sheet bar of a lead-calcium alloy, a sheet or a foil of a lead-silver-tin alloy consisting of 0.01-1.0% by weight of tin and a residual quantity of lead and having a thickness smaller than that of the sheet bar, pressure-bonding both the materials by cold rolling to prepare an elementary sheet, and subjecting the elementary sheet to an expanding process or a punching process.The grid obtained according to the process of the invention is improved in the charge-discovery characteristics after overdischarging and standing and does not deteriorate the maintenance-free characteristic of lead-calcium-tin alloy.

摘要： In casting tubular-plate grids, a molten lead alloy is poured into a mold along the long side of the grid perpendicular to the grid rods. Temporary connectors joining adjacent grid rods are simultaneously cast. These connecting portions have a thickened cross-section in the middle and a constricted cross-section at their points of junction with the grid rods. In a subsequent operation, the connecting portions are punched out.

摘要： A method of manufacturing a battery plate grid includes the steps of applying a layer of conductive material onto a mould, inserting a conductive battery plate lug having an extension integral therewith into the mould, filling the remainder of the mould with particles of a sinterable, thermo-plastic synthetic resin material, heating the synthetic resin material until the resin is fully sintered, the extension of the lug thereby being trapped by the sintered resin and the conductive material from the mould thereby becoming firmly adhered to the lower surface of the sintered resin as a continuous, conducting layer, cooling the sintered resin until it hardens, and then removing the resultant grid from the mould.
