A battery apparatus may include: one or more battery cells; one or more fire-extinguishing agents, which include(s) a component that provides a negative-catalyst effect with respect to combustion; and a casing, which houses the battery cell(s) and the fire-extinguishing agent(s). In the event that one or more of the battery cell(s) has (have) been subject to inappropriate handling and consequently has (have) ignited, the fire can be rapidly extinguished by the negative-catalyst effect of the fire-extinguishing agent(s). In addition, if one or more of the battery cell(s) of the battery apparatus has (have) ignited, because the fire can be rapidly extinguished, spreading of the fire to other battery cells, the casing, etc. can be inhibited.

A battery frame for providing structural support for a battery pack for retaining rows of stacked battery cells is provided. The battery frame includes a plurality of longitudinal beams and a plurality of crossbeams arranged between and connected to the longitudinal beams. The crossbeams are arranged in parallel to each other and include two outer crossbeams and an inner crossbeam. The inner crossbeam is arranged between the outer crossbeams. A retaining section for retaining one of the rows of stacked battery cells is provided between any neighboring pair of the crossbeams so that the rows of stacked battery cells and the inner crossbeam are alternately arranged between the two outer crossbeams. Each of the crossbeams is connected to the longitudinal beams by a plurality of fasteners extending in a longitudinal direction of the crossbeams through the longitudinal beams and into the crossbeams.

A cell carrier for a battery module, a battery module, and a method for assembling a battery module. The battery module includes a plurality of pairs of battery cells and the cell carrier. The cell carrier includes a plurality of recesses, each including a first recess portion including a first sidewall portion and a first bottom portion, and a second recess portion including a second sidewall portion and a second bottom portion. The first bottom portion and the second bottom portion of each recess include a shared cutout. For each pair of battery cells, a first end of a first battery cell is coupled to the first recess portion and a first end of a second battery cell is coupled to the second recess portion of a respective recess.

A multi-module battery pack includes a battery tray defining multiple battery tray compartments, battery modules each disposed within a corresponding one of the compartments, and a thermal barrier arranged in a predefined heat transfer path through the tray between an adjacent pair of the battery modules. The thermal barrier has a thickness of at least about 1 mm and a thermal conductivity of less than about 4 W/m-K, such that the thermal barrier blocks the heat transfer path to mitigate a thermal runaway event of one of the adjacent pair of battery modules. An electric powertrain system includes a rotary electric machine having phase leads and an output member, a driven load coupled to the output member, and the multi-module battery pack. A method includes providing the tray, identifying the heat transfer path, and arranging the thermal barrier in the heat transfer path.

A method of producing a battery with a prismatic battery housing includes assembling a battery housing from two prefabricated housing parts, of which the first housing part includes at least a partial region of the element including the at least one through hole as well as at least a partial region of a second element, bordering on the element including the at least one through hole, and the second housing part includes all elements and/or partial regions of elements not part of the first housing part.
