Abstract: Various embodiments of the present technology comprise a method and apparatus for a battery. According to various embodiments, the battery comprises a layered structure comprising a current collector, an active material, and a non-electrically conductive permeable layer. The layered structure is repeated with a separator disposed between adjacent layered structures.

Abstract: A nickel iron battery comprising a housing, an electrolyte solution contained within the housing, an anode comprising iron configured to be retained within the housing and the electrolyte solution, an cathode comprising nickel configured to be retained within the housing and the electrolyte solution, and a separator configured to be retained within the hosing and the electrolyte solution, wherein the separator is interposed between the cathode and the anode.

Abstract: A Nickel iron battery using a mono-block housing that has cells with leak-proof intercell connections. The intercell connections use compressed grommets to prevent fluid transfer between the cells. Each cell generates a charge that can be connected in series or parallel as required. The cells use an electrode plate that enables a manufacturing process which yields higher efficiency, higher throughput, and significantly lower battery cost. The anode composition of the cells has iron powder to increase cathode utilization, therefore lowering cathode material usage and lowering production cost.

Abstract: Bipolar plates for a lead acid battery and bipolar plate stack assembly comprising such plates is described. In another aspect, the subject matter describes, a lead acid battery comprising such bipolar plate stack assembly.

Abstract: A current collector for use in an energy storage device, particularly a lead-acid battery or lead-carbon capacitor, is provided. The current collector is woven from a plurality of weft composite wires and a plurality of warp composite wires. The composite wires include a core and a metal coating formed around the outer surface of the core. The core includes a plurality of longitudinally extending fibers radially arranged to define interstices between outer surfaces of adjacent fibers, and a matrix positioned within the interstices to such an extent that the core is substantially impervious to fluid (e.g., acid) penetration via capillary forces.

Abstract: A lead-acid battery including a case, a plurality of negative and positive electrode plates arranged in the case, a plurality of separators interposed between the negative and positive electrode plates, and a plenum stabilization material disposed within the case to maintain the positions of the electrode plates relative to one another and to other components within the case. The plenum stabilization material includes a compound that (i) is solid during normal operation of the battery and (ii) can undergo reversible physical change in state from solid to liquid when the battery is subjected to or is operated under abnormal conditions.

Abstract: A lead-oxide paste mix for use as an active material superimposed upon the plates of a lead-acid rechargeable battery. Battery grades of oxides of lead are mixed with a dilute solution of hydrogen peroxide, either alone or with additives and/or expanders. The resultant paste offers such advantages as reduced curing and drying times and/or the elimination of the need for curing and drying, lower dry active material weights and improved cohesion when compared to conventional pastes manufactured from leady oxides, sulfuric acid, and water.
