A battery module has an improved gas venting structure, and a battery pack including the same. Heat emission efficiency of a battery cell can be improved, and the outflow of sparks or embers can be blocked even when a thermal runaway of a battery cell occurs by forming a bracket formed at a position where mesh structures are alternately formed, at an inside a plate where mesh structures are formed.

The present invention relates to a battery module comprising a particulate metal-dispersed thermal conductive resin, and a method and a system for inspecting same. The present invention can effectively inspect the degree of dispersion in the resin in a nondestructive manner and can detect a defect.

Battery module comprising metal particle-dispersed thermal conductive resin and method and system for inspecting same

A method of manufacturing a battery cell assembly in which a plurality of battery cells are stacked includes a step of coupling battery cells adjacent to each other among the plurality of battery cells using a one-component liquid material, wherein the one-component liquid material is coated onto at least one battery cell of the battery cells adjacent to each other by a spray-coating method.

Battery cell assembly, method of manufacturing the same and battery module including battery cell assembly

A battery pack includes a battery cell stack formed by a plurality of stacked battery cells, a battery module housing configured to wrap the other outer surfaces of the battery cell stack excluding a first surface and a second surface, from which electrode leads protrude, a water tank configured to supply a coolant to the battery cell or the battery module housing, and a battery pack case configured to receive a plurality of battery module housings. The battery pack case includes a pack case space portion located adjacent to the first surface and a crossbeam located adjacent to the second surface, whereby, when fire breaks out in the battery cell, it is possible to rapidly and accurately prevent spread of flames of the ignited battery cell.

Battery pack including thermal spread inhibition structure

A battery module includes a battery cell stack constituted by a plurality of stacked pouch-shaped battery cells, a battery module housing configured to receive the battery cell stack, and a heat dissipation member coupled to a portion of the battery module housing, wherein the heat dissipation member has a through-hole formed in a heat dissipation plate disposed so as to face the battery cell stack and a sealing member is added to the through-hole, and a method of manufacturing the heat dissipation member. It is possible to effectively prevent thermal runaway of a battery cell that has caught fire while minimizing an increase in volume of the battery module.

A method of mounting a bus-bar frame includes: forming a plurality of cell lead blocks and a battery cell stacked body by alternately stacking a cell lead block and at least one battery cell; disposing a top cover with respective ends on which a bus-bar frame is installed so as to cover the battery cell stacked body; removing the lead blocks from a space between the battery cell stacked body and the bus-bar frame; and installing the bus-bar frame on the battery cell stacked body by rotating the bus-bar frame. The alternately stacking of the cell lead block and the at least one battery cell includes positioning an electrode lead protruding from each battery cell between neighboring ones of the cell lead blocks.

Mounting method of bus-bar frame

A battery module includes a battery cell stack in which a plurality of battery cells are stacked; a plate disposed to contact the plurality of battery cells on a side surface of the battery cell stack and disposed in a direction parallel to a stacking direction of the plurality of battery cells included in the battery cell stack; and an adhesive layer applied to the plate to contact the battery cell stack and the plate. A battery pack can include the battery module.
