  • BATTERY COVER FOR PREVENTION OF ELECTROLYTE LEAKAGE
    Publication number: 20140147733
    Abstract: In a battery cover, a sealed assembly structure of upper and lower covers of a battery case is configured in such a way that it forms a labyrinth structure that can allow an electrolyte to move upward and downward, thereby increasing an electrolyte leakage resistance of the battery case. Gas discharge holes and micro-holes are formed in the battery cover, and so the battery cover can easily discharge gas from the battery case. In the battery cover, electrolyte recovery ports are arrayed in such a way that the electrolyte can be prevented from leaking from the battery case even when the battery case is turned over or tilts to one side.

  • Battery cover
    Patent number: 5840439
    Abstract: The present invention is directed to a leak resistant battery cover for storage batteries. The battery cover sealably engages a conventional battery housing having multiple cells separated by internal housing walls. The cover has a substantially flat interior area, a portion of which extends over part of each battery cell when the cover is placed upon a battery housing. The cover includes a cell chamber for each battery cell. Drain-back/vents communicate each cell chamber with its corresponding battery cell. The drain-back/vent, whether separate or integrated allows escape of electrolyte gases from the battery cells into the corresponding battery chamber and provide for the return of liquid electrolyte back to the cells from the cell chambers. None of the cell chambers communicate directly through the battery cover to atmosphere.One or more additional chambers are provided in the cover above the central cells of the battery housing.

  • Battery with side terminal
    Patent number: 7491466
    Abstract: The invention is a battery with power output terminals on opposite ends of a battery and a power output terminal on the side wall of the battery that has the same polarity as one of the end power output terminals. The presence of the side terminal is indicative of a battery characteristic and allow a battery operated device requiring that characteristic to selectively use the battery when designed to use the side terminal and opposite polarity end terminal to provide energy to operate the device. Because the battery also has opposite polarity end terminals, the battery can be used in devices designed to use batteries of the same dimensions and having the same nominal voltage. The location of the side terminal can also be indicative of additional battery characteristics, allowing the selective use of batteries in devices based on various device requirements.

  • Mechanical and thermal improvements in metal hydride batteries, battery modules and battery packs
    Patent number: 6878485
    Abstract: Mechanically and thermally improved rechargeable batteries, modules and fluid-cooled battery pack systems. The battery is prismatic in shape with an optimized thickness to width to height aspect ratio which provides the battery with balanced optimal properties when compared with prismatic batteries lacking this optimized aspect ratio. The optimized thickness, width and height allow for maximum capacity and power output, while eliminating deleterious side affects. The battery case design allows for unidirectional expansion which is readily compensated for by applying external mechanical compression counter to that direction. In the module, the batteries are bound within a module bundling/compression means under external mechanical compression which is optimized to balance outward pressure due to expansion and provide additional inward compression to reduce the distance between the positive and negative electrodes, thereby increasing overall battery power.
