Abstract: A traction battery assembly, includes a thermal exchange frame configured to communicate a coolant that manages thermal energy levels within a traction battery pack, and an plurality of busbars held by the thermal exchange frame. A thermal management method includes moving a coolant through a thermal exchange frame to manage thermal energy levels of a battery array, and holding a plurality of busbars with the thermal exchange frame.

Abstract: Immersion thermal management systems are provided for managing thermal energy in a traction battery pack. An exemplary immersion thermal management system may utilize an edge cooling scheme in which a coolant contacts minor side surfaces (e.g., top, bottom, and ends) of battery cells of the traction battery pack but does not flow across major side surfaces (e.g., faces) of the battery cells. The edge cooling scheme provides adequate cooling without adding volume and mass to the traction battery pack.

Abstract: A battery pack venting assembly includes a battery pack enclosure assembly providing an battery pack interior, and cell stacks within the battery pack interior. Each cell stack includes a plurality of battery cells. Module enclosure assemblies are also within the battery pack interior. Each of the module enclosure assemblies houses one or more of the cell stacks. An exhaust trunk extends through the battery pack enclosure assembly from the battery pack interior to an area outside the battery pack interior. Exhaust branches within the battery pack interior each extend from one of the module enclosure assemblies to the exhaust trunk.

Abstract: Battery arrays are provided for traction battery packs. An exemplary battery array may include a thermal barrier foam system that includes one or more foam blocks arranged to fill void spaces within the battery array to mitigate cell-to-cell and/or array-to-array thermal propagation. The foam blocks may be secured to hook structures of a bus bar module of the battery array. The hook structures can be integrated as part of the bus bar module or part of a separate structure that is attachable to the bus bar module.

Abstract: A traction battery pack assembly includes a coolant reservoir that receives coolant from a traction battery pack. The coolant reservoir is configured to receive the coolant in a direction that causes the coolant to swirl within the coolant reservoir.

Abstract: The present invention provides composite electrodes that comprise a titanium metal filler and a polymeric material. Advantageously the composite electrodes of the present invention do not suffer from the problems of carbon degradation, are thermally stable, are easily shaped, which demonstrate high power densities and which are relatively inexpensive to produce.

Abstract: Contemplated configurations and methods allow for effective removal of copper from aqueous media by selectively concentrating copper in a first stage, wherein competing metal ions are subjected to a redox reaction to thereby increase selective concentration. Copper is then plated in a flow through electrode from a relatively concentrated copper solution that is depleted from competing non-copper metals. In preferred aspects, the first stage provides a copper-depleted effluent that includes zinc and/or manganese for further recovery.

Abstract: Perchlorate is removed and effectively destroyed in devices and methods that employ a eluting solvent in which the anion of an acid solubilizes Ti (III), which may be electrochemically generated or added in situ. Using such solvents, destruction of perchlorate is unexpectedly and several orders of magnitude faster than using solvents without solubilizing acids. In most preferred aspects, the solubilizing acid is methane sulfonic acid and/or sulfamic acid, and Ti (III) is electrochemically generated. Perchlorate destruction will then result in formation of Ti (IV), which may be present in the eluent in a subsequent elution.
