Abstract: A system includes a prismatic battery assembly including an enclosure, an air flow inlet, an air flow outlet, an air flow channel, and a vent channel. The enclosure has a first end, a second end, a first side wall, and a second side wall. The air flow inlet is disposed at the first side wall, and the air flow outlet is disposed at the second side wall. The air flow channel extends within the enclosure between the air flow inlet and the air flow outlet. The vent channel has a gas vent inlet that is fluidically connected to the air flow channel. The system also includes an air flow source configured to direct air flow from the air flow inlet along the air flow channel and out the air flow outlet. The air flow draws heated vent gasses away from the prismatic battery assembly.

Abstract: A hair combing device includes a brush main body. The brush main body includes a front scraping plate, a rear scraping plate and a row comb. A mounting cavity is defined in the brush main body. A first opening is in communication with the mounting cavity. The row comb is partially positioned in the mounting cavity. The front scraping plate and the rear scraping plate are arranged above a front surface of the row comb and below a back surface of the row comb respectively. The row comb moves telescopically along a length extension direction of the front scraping plate and the rear scraping plate under the action of external force, thereby simultaneously pushing the hair from different directions, allowing a hair to be smoothly pushed out from a comb tooth gap towards a top end of comb tooth. This structure can effectively improve the efficiency of hair combing.

Abstract: A prismatic battery assembly includes a cell, a heat dissipating element, and a layer of anisotropic material. The cell includes an enclosure having a first end, a second end, a side wall extending between the first end and the second end, and a terminal disposed at the first end. The heat dissipating element extends along the second end. The layer of anisotropic material extends in a direction parallel to the side wall and has a first level of thermal conductivity in the direction parallel to the side wall and a second level of thermal conductivity in a direction transverse to the side wall. The first level of thermal conductivity is greater than the second level of thermal conductivity. Heat generated within the enclosure of the cell is dissipated along the layer of anisotropic material in the direction parallel to the side wall and into the heat dissipating element.

Abstract: A battery system for a motor vehicle or another electrical system includes a battery cover, one or more battery cells, and a diverter assembly. The cells define a battery cavity in fluid communication with a corresponding vent opening. An air gap may be defined in an exhaust volume within the battery system. The diverter assembly includes a diverter body arranged relative to the vent openings. The diverter body is moveable or stationary. In response to a thermal propagation event occurring in the module or at least one of the battery cells, each diverter body diverts a high-temperature flow of ejecta from the cavity into an exhaust volume in a predetermined flow direction when the flow of ejecta passes through the vent opening. The diverter assembly may include a support member connected to the diverter body and connectable to the battery cell.

Abstract: A vehicle battery cell venting system includes a battery pack providing electrical power for propulsion of a vehicle. A battery cell includes a battery can enclosing components including an electrolyte. A battery end cap captures an electrolyte portion. A mandrel has a longitudinal bore, the mandrel extending through the electrolyte and disposed on a battery can center axis. An electrolyte generated gas may pass through the longitudinal bore. A shaft is slidably disposed within the longitudinal bore, with a shaft proximal fixed to a vent cap portion of the battery end cap. A circular scoring created in the battery end cap releasably fixes the vent cap portion to the battery end cap and is frangible allowing the vent cap portion to separate from the battery end cap and for the vent cap portion together with the shaft to displace when a battery cell overpressure condition is created.
