Abstract: An Advanced Graphite, with a lower degree of ordered carbon domains and a surface area greater than ten times that of typical battery grade graphites, is used in negative active material (NAM) of valve-regulated lead-acid (VRLA) type Spiral wound 6V/25 Ah lead-acid batteries. A significant and unexpected cycle life was achieved for the Advanced Graphite mix where the battery was able to cycle beyond 145,000 cycles above the failure voltage of 9V in a non-stop, power-assist cycle-life test. Batteries with Advanced Graphite also showed increased charge acceptance power and discharge power compared to control groups.

Abstract: The invention relates to a cell connector (6) for a battery, especially for absorbing, in conjunction with at least one damping element (9), the vertical forces that are caused by the impact of shocks. The cell connector (6), at one end, is connected to the positive or negative electrodes (4, 5) which are received in a housing (2) having a housing cover (3), and, at the other end, comprises at least one terminal (7, 8) projecting from the housing cover (3). The aim of the invention is to elastically dampen the electrode plates (4, 5) of an accumulator (1) which are disposed inside a housing (2). For this purpose, a terminal (6) having a supporting shoulder (11), integrally molded thereto, is used in the housing (2), a damping element (9), disposed between the housing cover (3) of an accumulator (1) and the cell connector (6), coming to rest thereon.

Abstract: A method of synthetic imaging comprising the steps of: emitting a first electromagnetic signal having a first frequency from a first radiation source, emitting at least one second electromagnetic signal having a second frequency from a second radiation source, wherein the first and second frequencies are different from each other, substantially simultaneously receiving the first signal and the second signal with a first receiver, substantially simultaneously receiving the first signal and the second signal with at least one second receiver, arranging an object on the path of at least one electromagnetic signal between the radiation sources and the receivers, wherein the signals are reflected by the object before they meet the receivers, and computing an image of the object from the signals received by the receivers and a device for practicing the method.

Abstract: The present invention concerns a tube plate for an electrode, preferably a positive electrode, of a lead acid battery, wherein the tube plate (2) has an upper frame (3) and a plurality of lead or lead alloy cores (1) extending substantially parallel from the upper frame (3). To provide a tube plate for an electrode of a lead acid battery, with which a lower current density and shorter current paths or diffusion paths for reducing the electrical resistance in comparison with tube plates in accordance with the state of the art are achieved, with the same use of material, it is proposed according to the invention that in the cross-section relative to their longitudinal extent the cores (1) have a surface profile with at least three convex portions (11) and at least three concave portions (12), wherein convex and concave portions (11, 12) alternate in the course of the surface profile.

Abstract: A venting plug for a wet, lead-acid storage battery, a battery containing the same, a method of molding the venting plug body, and a mold for molding the venting plug body are disclosed. The sealing surfaces of the venting plug do not include a mold parting line along which acid from inside of the battery could seep between the seal and sealing surfaces. The venting plug body, however, includes a coupling structure that includes a mold parting line. The sealing surfaces of the venting plug body are molded by a single plate such that no mold parting line results along the sealing surfaces, while the coupling structure is molded by plurality of mold components such that a mold parting line results in the vicinity of the coupling structure.

Abstract: Disclosed are energy storage cells and battery systems made therefrom which can provide a regulated, constant voltage to a load independent of the charge state of the cells and other factors, such as cell polarization, which may cause the battery's output voltage to vary. In an illustrative embodiment, the battery system includes a dc-dc converter and a reference voltage circuit. The converter draws power from one or more energy storage cells and upconverts or downcoverts to provide an output voltage that matches the reference voltage.

Abstract: A battery rack system for stationary power applications is provided. The rack systems includes a rack assembly configured so as to be seismically rated for UBC Zone IV requirements. The rack assembly has a plurality of shelves which are supported by a rack frame such that each shelf along with the rack frame defines a respective cell-receiving area having a front opening. Each shelf has at least one associated cell restraint that is removably connected to the rack assembly. The restraint spans across the front opening to the respective cell-receiving area so as to restrain movement of a cell arranged therein. The system includes at least one channel disposed within the footprint of the rack frame which extends so as to provide a passage between adjacent cell-receiving areas for accommodating wires used to couple cells stored in the rack system together.
