Abstract
A battery module according to an embodiment of the present disclosure includes a battery cell stack containing a plurality of battery cells stacked along one direction, and a module frame for housing the battery cell stack. The battery cells adjacent to each other in the battery cell stack are coupled together by a first adhesive member including a cured spray-type adhesive is cured. The first adhesive member follows at least one fluctuating pattern that extends along a direction different from the direction along which the plurality of battery cells are stacked.
Claims20
A battery module comprising:
- a battery cell stack containing a plurality of battery cells stacked along a first direction, and
- a module frame for housing the battery cell stack,
- wherein the battery cells adjacent to each other in the battery cell stack are coupled together by a first adhesive member including a cured spray adhesive,
- wherein the first adhesive member follows at least one fluctuating shape extending along a second direction transverse to the first direction, and
- wherein the fluctuating shape of the first adhesive member is maintained when the plurality of battery cells are stacked.
A method for manufacturing a battery cell assembly containing a plurality of battery cells, the method comprising the steps of:
- moving an adhesive from an adhesive tank to a spray gun,
- spraying the adhesive through a nozzle of the spray gun and onto a surface of at least one of the plurality of battery cells, the adhesive being sprayed onto the surface of the at least one battery cell to form a fluctuating shape, and
- stacking the plurality of battery cells along a stacking direction,
- wherein the adhesive forms an adhesive member that maintains the fluctuating shape when the plurality of battery cells are stacked.
