Abstract:
An apparatus for storing one or more battery modules (100) comprising a containment tray (300, 500, 700, 1000) defined by opposing front and back faces (314, 316, 714, 716, 1014, 1016), opposing side faces (318, 718, 1018), and opposing top and bottom surfaces (310, 312, 522, 532, 710, 712 1010, 1011, 1012) oriented perpendicular to the front, back, and side faces, wherein the containment tray has a receiving area (302, 518, 702, 1002) formed in the top surface for receiving one or more battery modules, the receiving area comprising a receiving surface (320, 520, 720, 1020) oriented parallel to and located between the opposing top and bottom surfaces for supporting the one or more battery modules.
Abstract:
The present invention provides a terminal assembly, and storage batteries comprising a terminal assembly, wherein the terminal assembly comprises a conductive cup-shaped member comprising a terminal wall in electric communication with a terminal of the electrochemical cell when the terminal wall is in contact with the terminal; a sidewall; and a rim separated from the terminal wall by the sidewall; and a bipolar endplate having first and second surfaces coplanar with the terminal wall and joining to the rim at the first surface, the joining enabling bi-directional uniform current flow through the cup-shaped member between the terminal and the endplate when the terminal wall is in contact with the terminal, the endplate having an electrochemically active region comprising a first surface area enclosed by the rim and a remaining second surface area outside an outer periphery of the rim, the first and second surface areas being substantially equal.
Abstract:
The present invention provides an aqueous electrolyte for use in rechargeable zinc-halide storage batteries that possesses improved stability and durability and improves zinc-halide battery performance. One aspect of the present invention provides an electrolyte for use in a secondary zinc bromine electrochemical cell comprising from about 30 wt% to about 40 wt% of ZnBr2 by weight of the electrolyte; from about 5 wt% to about 15 wt% of KBr; from about 5 wt% to about 15 wt% of KCl; and one or more quaternary ammonium agents, wherein the electrolyte comprises from about 0.5 wt% to about 10 wt% of the one or more quaternary ammonium agents.
Abstract:
The present invention provides a bipolar electrode that is useful in zinc-halide electrochemical cells or battery stacks. The bipolar electrode comprises a titanium bipolar electrode plate wherein a cathode assembly is disposed on a front surface of the electrode plate. The cathode assembly comprises a titanium cathode cage, a separator, and carbon material, wherein the cathode cage holds the carbon material in electrical communication with the front surface of the electrode plate.
