Abstract
The present invention provides a method of manufacturing a battery module, which includes: stacking a plurality of battery cells; applying a thermal conductive member to at least a part of one side of the plurality of battery cells; and bring a cooling plate into contact with the one side of the plurality of stacked battery cells after applying the thermal conductive member, wherein the one side of the plurality of battery cells is an adhesion part which is formed by adhering a case to the electrode assembly on one side except for three sides on which a sealing part is formed by adhering the case among circumferential surfaces of the battery cell in a longitudinal direction thereof.
Claims20
A method of manufacturing a battery module, comprising:
- stacking a plurality of battery cells in a front-back direction, each battery cell having a front surface, a rear surface, and four sides, and including a case enclosing an electrode assembly to form a close contact part on one side of the four sides;
- applying a thermal conductive member on the close contact part of each battery cell;
- and
- placing a cooling plate on the one side of the plurality of battery cells, the cooling plate forming a first surface being flat and facing the one side of the plurality of battery cells,
- wherein the case includes a pouch forming the close contact part on a single sheet of the pouch.
A battery module comprising:
- a plurality of battery cells;
- a cooling plate disposed over one side of the plurality of the battery cells, the cooling plate forming a first surface being flat and facing the one side of the plurality of the battery cells;
- and
- a thermal conductive member disposed between the one side of the plurality of the battery cells and the cooling plate,
- wherein the battery cell includes:
- an electrode assembly;
- an electrode tab being drawn from the electrode assembly;
- and
- a case surrounding the electrode assembly, the case including a pouch forming a close contact part on a single sheet of the pouch at the one side of the battery cell.
