Cold plate blade for battery modules
A cold plate for a battery may comprise channels that extend from a first end of the plate to a second end of the plate or from a first side of the plate to a second side of the plate, the channels are located in parallel with each other and between the top surface and the bottom surface. The channels may be separated from each other by walls. The plate may be milled to form a first manifold on each end. The plate may also be milled to form notches in the surface(s) over the manifold. A port for the inlet and a port for the outlet of a working fluid may be inserted into the notches. The plate may have end caps, and the end caps and the ports may be welded or brazed to form a sealed enclosure. In various embodiment, the plate is an extruded plate, a cast plate, or a stamped/formed plate.
Battery module
A battery module including: a battery stack of battery cells having opposite ends to which a plurality of electrode tabs are connected; end-side bus bar assemblies formed at opposite ends of the battery stack, respectively, and electrically connecting the electrode tabs of the battery cells; and a case accommodating the battery stack and the end-side bus bar assemblies.
ELECTRICAL ENERGY STORAGE DEVICE WITH EFFICIENT HEAT DISSIPATION
An electrical energy storage device includes prismatic energy storage cells arranged adjacent to one another such that interfaces of adjacent storage cells run at a distance from one another such that the interfaces of the adjacent storage cells form an intermediate space. A respective first layer is arranged between the interfaces of adjacent storage cells, the first layer abutting one of the two interfaces of the adjacent storage cells under pressure. Either the respective first layer also abuts the second of the two interfaces of the adjacent storage cells under pressure, or a second layer is arranged between the interfaces of adjacent storage cells, the second layer abutting the second of the two interfaces of the adjacent storage cells under pressure. A heat-conducting device is arranged in or between the first layer and the second layer is conducted out of the intermediate space between the adjacent storage cells.

BATTERY CELL THERMAL RUNAWAY BARRIER
A thermal runaway barrier for at least significantly slowing down a thermal runaway event within a battery assembly. The thermal runaway barrier consisting essentially of a single-layer of a nonwoven fibrous thermal insulation comprising a fiber matrix of inorganic fibers, thermally insulative inorganic particles dispersed within the fiber matrix, and a binder dispersed within the fiber matrix so as to hold together the fiber matrix. An optional organic encapsulation layer may also be used to encapsulate the nonwoven fibrous thermal insulation.
