A battery module includes a plurality of battery cells; and a module case accommodating the plurality of battery cells, wherein the module case include an upper plate positioned on the plurality of battery cells and a lower plate positioned below the plurality of battery cells, each having a channel in which a coolant flows, the upper plate and the lower plate include a melting spot which melts when heated in a first plate in contact with the plurality of battery cells, and the upper plate includes a vent hole and a first sealing cap in a second plate which faces the first plate, the vent hole through which gas is forced out, and the first sealing cap configured to seal the vent hole and made of a thermomeltable material.

Battery module with thermal propagation prevention structure of battery cell using coolant and battery pack comprising the same

A battery module prevents a fire from increasing in size and prevents electrical short circuits due to dew condensation in case of a fire. A battery module for achieving the object as described above includes a cell assembly having a plurality of battery cells, a front cover including an upper wall, a lower wall, a left wall, and a right wall, which form an inner space, and a module case accommodating the cell assembly in the inner space, coupled to the front cover, and provided with a cover portion that has a portion protruding to face at least one of the upper wall, the lower wall, the left wall, and the right wall.

Battery module, battery rack, and power storage device

A battery module includes a cell stack formed by stacking a plurality of battery cells including a receiving portion in which an electrode assembly is accommodated, a first edge portion and a second edge portion along the longitudinal direction around the receiving portion, and a third edge portion and a fourth edge portion along the width direction, in the vertical direction with the receiving portions facing each other, the battery cell includes a resealing portion at the first edge portion, and includes a sealing portion or an unsealed portion at the second edge portion, and the first edge portion and the second edge portion are alternately positioned along the vertical direction on both sides of the cell stack.

Battery module, and battery pack and energy storage system including the same

A battery module includes a plurality of cell assemblies including a plurality of secondary batteries; a module housing including an accommodation space configured to accommodate the plurality of cell assemblies; and a blocking member configured to, when a gas pressure more than a predetermined gas pressure or a heat more than a predetermined temperature is generated in at least some cell assemblies among the plurality of cell assemblies, block the generated gas or heat from moving to the other cell assemblies.

A spot welding jig is provided. The spot welding jig presses electrode leads of battery cells to be closely adhered onto a bus bar when spot welding is performed to the electrode leads interposed on the bus bar along a width direction of the electrode leads. The spot welding jig includes a passing portion through which a welding laser passes, and a predetermined number of barriers configured to vertically partition an inner space of the passing portion.
