A battery module includes a plurality of battery cells; an accommodation part to surround circumferences of the battery cells and having an accommodation space therein in which the battery cells are accommodated, the accommodation part having opened upper and lower portions; a cooling fluid supply part connected to one side of the accommodation part to supply a cooling fluid into the accommodation part; a cooling fluid discharge part connected to the other side of the accommodation part to discharge the cooling fluid within the accommodation part; a first blocking part above the accommodation part to block the opened upper portion of the accommodation part; and a second blocking part below the accommodation part to block the opened lower portion of the accommodation part and support the battery cells. A path through which the cooling fluid supplied into the accommodation space flows is defined between the battery cells.

A battery pack includes a battery assembly including battery cells parallel to one another and an outer case. Each battery cell includes a discharge valve provided on an end surface thereof, and an end-surface electrode provided at an end portion thereof. A welding surface of the lead plate is connected to the end-surface electrode arranged on the same plane. The battery pack includes a backflow-restricting layer disposed on a non-welding surface of the lead plate in the outer case. The lead plate has a gas permeation gap therein allowing a gas discharged from the discharge valve to pass in a discharge direction of the backflow-restricting layer. The backflow-restricting layer includes a resistance part configured to allow the gas passing through gas permeation gap to pass in the discharge direction, and to suppress or prevent the exhaust gas from passing in a direction opposite to the discharge direction.

A high voltage battery module comprising a plurality of low voltage battery assemblies and a method for manufacturing a high voltage battery module are provided.

A battery module and a method of assembling the battery module are provided. The battery module includes a cooling surface having a first area and a second area with different cooling capacities, an adhesive including a first component having a first thermal conductivity and a second component having a second thermal conductivity, and a first battery and a second battery. The first battery is secured to the first area by a first portion of the adhesive and the second battery is secured to the second area by a second portion the adhesive. The first portion of the adhesive has a first ratio of the first component to the second component and the second portion of the adhesive has a second ratio of the first component to the second component. The first and second ratios are different and compensate for the different cooling capacities of the first and second areas.

A system for thermal management and structural containment includes a first battery cell having first and second terminal ends, and a first capillary void matrix disposed about an outer casing of the first battery cell.

A battery assembly for a lighting fixture is provided. The battery assembly includes a battery unit comprising a battery unit housing and a first set of conductive pins. The battery unit housing is configured to accommodate one or more batteries configured to power one or more light sources of the lighting fixture. The first set of conductive pins are in electrical communication with the batteries. The battery assembly includes a battery interface comprising a battery interface housing and a second set of conductive pins. The battery interface housing is configured to accommodate the battery unit housing. The second set of conductive pins are coupled to the light source(s) so that the batteries power the light source(s) when the first set of conductive pins contact the second set of conductive pins. In some implementations, the battery unit can be inserted into the battery interface while the lighting fixture is energized.
