| 20090242072 | POSITIVE ELECTRODE PLATE FOR ALKALINE STORAGE BATTERY AND METHOD FOR PRODUCING THE SAME - An alkaline storage battery including a strip-shaped porous metal substrate and a material mixture filled into the substrate. The substrate has an unfilled portion where the material mixture is not filled along at least one of two longitudinal sides of the substrate. The substrate has a weight per unit area of 150 to 350 g/m | 10-01-2009 |
| 20090255604 | PASTING APPARATUS AND METHOD - An apparatus and method operations are provided for battery plate fabrication, in particular for applying paste to battery plate grids. A conveyer-type pasting machine includes a conveyer belt for moving battery plate grids under a new type of paste dispensing hopper, which includes closely spaced knurled rollers and an angled paste deflector member, which cooperate to generate a pressurized stream of paste for extrusion thru the battery plate grid. The apparatus also includes a specialized grid support sheet that also enables a consistent layer of paste to be applied to both exterior sides of a manufactured battery plate grid by enabling application of paste to one side of the grid and facilitating transmission of the paste through to and past the opposite, exterior side of the grid. | 10-15-2009 |
| 20120111444 | FILL PORT FOR ELECTRIC VEHICLE BATTERY ENCLOSURE - An apparatus and method providing for coolant agent ingress of a high energy density battery enclosure during an internal thermal event. A solution includes a specialized battery enclosure and, in some embodiments, an associated vehicle structure providing a normally closed, pressure activated fill port. Preferably the fill port is positioned so an operator of the fill port is clear from any hot gases exiting from the enclosure. | 05-10-2012 |
| 20120111445 | PERFORATION APPARATUS AND METHOD FOR ELECTRIC VEHICLE BATTERY ENCLOSURE - A perforation tool for a battery enclosure system of a vehicle battery pack, comprising: an engaging tip configured to mechanically breach a thermal-control-agent-retaining enclosure of a traction battery pack including a plurality of interconnected batteries with the enclosure reinforced for mechanical protection of the batteries when installed in an electric vehicle; a port for receiving a thermal-control agent having a pressure in a range of about 5-100 psi; and a housing, coupled to the tip and to the port, wherein the tip includes an aperture and wherein the housing includes a channel communicating the port to the aperture wherein the pressurized thermal-control agent is produced at the tip at about the pressure. | 05-10-2012 |
| 20130025741 | APPARATUS FOR SUPPLYING ELECTROLYTE - An apparatus that supplies electrolyte inside a battery case disposed inside a reduced pressure chamber includes: a measuring unit where a piston moves in a first direction in a measuring space (S) inside a cylinder, a dispenser that injects electrolyte from above into a battery case, a first pipeline that connects an upper end portion of the measuring space (S) of the measuring unit and the dispenser, and a back pressure valve disposed on the first pipeline. The dispenser includes a discharge nozzle disposed inside the battery case or in a periphery of an upper end of the battery case, a needle valve that is disposed inside the discharge nozzle and opens and closes the discharge nozzle, and an actuator that drives the needle valve up and down. | 01-31-2013 |
| 20150096645 | BATTERY PLATE GRID STRIP PASTING ASSEMBLY - A battery plate grid strip pasting assembly can include an orifice plate, a support structure, and a belt. The orifice plate has an opening through which battery paste material is dispensed out of a hopper. The support structure underlies a battery plate grid strip and supports the battery plate grid strip upstream of the opening. The belt traverses beneath the orifice plate and carries the battery plate grid strip downstream of the opening and downstream of the support structure. The support structure supports the battery plate grid strip above the belt and a gap is provided between a bottom surface of the battery plate grid strip and a top surface of the belt. Battery paste material is dispensed into the gap, through the battery plate grid strip, and overpastes the bottom surface of the battery plate grid strip. | 04-09-2015 |
| 20150129081 | Fuel System Using Redox Flow Battery - An automotive or other power system including a flow cell, in which the stack that provides power is readily isolated from the storage vessels holding the cathode slurry and anode slurry (alternatively called “fuel”) is described. A method of use is also provided, in which the “fuel” tanks are removable and are separately charged in a charging station, and the charged fuel, plus tanks, are placed back in the vehicle or other power system, allowing fast refueling. The technology also provides a charging system in which discharged fuel is charged. The charged fuel can be placed into storage tanks at the power source or returned to the vehicle. In some embodiments, the charged fuel in the storage tanks can be used at a later date. The charged fuel can be transported or stored for use in a different place or time. | 05-14-2015 |
| 20150364746 | APPARATUS AND METHOD FOR FILLING A CELL OF A RECHARGEABLE BATTERY WITH ELECTROLYTE LIQUID | 12-17-2015 |
