摘要： A battery grid is disclosed. The battery grid includes a pattern of grid wires. The pattern includes a grid wire having a first segment with a first corrosion resistance and a second segment with a second corrosion resistance which is less than the first corrosion resistance. The second segment corrodes at a rate which is faster than the corrosion rate of the first segment so as to dynamically release internal stress and control grid growth of the battery grid during its service life. A battery includes said grid and a method of forming said grid are also disclosed.

摘要： A battery paste application tooling assembly includes a hopper, a connector assembly, and a clamp assembly. The battery paste application tooling assembly can be equipped in a pasting machine. The hopper receives battery paste material. The hopper has an orifice plate with an orifice therein. The connector assembly is engageable with the orifice plate and disengageable therefrom. The clamp assembly is movable between a first position and a second position. In the first position, the clamp assembly releasable secures the orifice plate to the hopper. In the second position, the clamp assembly permits removal of the orifice plate from the hopper.

摘要： An electrical storage device includes high surface area fibers (e.g., shaped fibers and/or microfibers) coated with carbon (graphite, expanded graphite, activated carbon, carbon black, carbon nanofibers, CNT, or graphite coated CNT), electrolyte, and/or electrode active material (e.g., lead oxide) in electrodes. The electrodes are used to form electrical storage devices such as electrochemical batteries, electrochemical double layer capacitors, and asymmetrical capacitors.

摘要： An apparatus and process for melting and using scrap pieces of lead or lead alloy from making a web of connected grids for a lead acid battery by forming holes through a solid strip of lead or lead alloy. The scrap pieces may be compacted into briquettes which are submerged in a pool of liquid lead or lead alloy below the top surface of the pool and melt in the pool. Liquid lead from the pool may be cast into solid strips from which webs of grids are made.

摘要： A bipolar battery (1) comprising a stack of multiple bipolar plates (9) sandwiched between two monopolar plates (6, 8) is disclosed. The bipolar plates (9) each comprise a conductive polymer core (22) and an integrally formed non-conductive polymer surround (4), a layer of cathode material (16) on a first side of the bipolar plate (9), and a layer of anode material (28) on a second, opposite side of the bipolar plate (9). The integrally formed non-conductive polymer surround (4) extends from the conductive polymer core (22) further on one side than the other, such that on one side a first recess (19) is defined for accommodating electrolyte material of the battery (1). The layers of anode material (28) and cathode material (16) are contained within a casing formed at least in part by the integrally formed non-conductive polymer surrounds (4) of all of the bipolar plates (9).

摘要： This application provides a negative electrode plate, a lithium metal battery, and an apparatus including the lithium metal battery. The negative electrode plate includes a negative electrode current collector and a lithium-metal negative electrode disposed on at least one surface of the negative electrode current collector, where a polymer protective film is disposed on a surface of the lithium-metal negative electrode away from the negative electrode current collector, the polymer protective film includes a citric acid copolymer, and a number-average molecular weight Mn of the citric acid copolymer is 10,000 to 1,000,000. In this application, a polymer protective film with high tensile strength, high puncture strength, high elongation, and high electrolyte holding capacity may be formed on the surface of the lithium-metal negative electrode in the negative electrode plate.

摘要： The invention relates to a laminar textile material for covering a pasty active mass on a battery electrode. The invention further relates to a battery electrode having such a material, to a battery, and to a method for producing battery electrodes. Potential improvements of lead batteries are disclosed that are more practical than previously known solutions, and that stabilize the pasty active mass on the battery electrodes. A laminar textile material is disclosed to this end, comprising glass fibers and fibers made of a thermoplastic, e.g. polyester.

摘要： The present disclosure or invention is directed to novel or improved separators for a variety of lead acid batteries and/or systems. In addition, exemplary embodiments disclosed herein are directed to novel or improved battery separators, separator profiles, separator and electrode assemblies incorporating the same, battery cells incorporating the same, batteries incorporating the same, systems incorporating the same, and/or methods of manufacturing and/or of using the same, and/or the like, and/or combinations thereof. For example, disclosed herein are exemplary embodiments of improved electrode plate and separator assemblies (400) for lead acid batteries, improved lead acid cells or batteries incorporating the improved assemblies, systems or vehicles incorporating the improved assemblies (400) and/or batteries (100), and methods related thereto. The electrode plate (200, 201) may have a grid (202) of a stamped, cast, or expanded metal manufacturing process. The grid (202) may have a non-uniform application of active material (203). The separators (300) provide a support structure for resisting or mitigating any plate warping or plate deflection.
