1. A battery module comprising:
a cell stack including a plurality of pouch-type secondary batteries stacked along a stacking dimension;
a first busbar frame mounted on a first end of the cell stack, the first end of the cell stack being opposite to a second end of the cell stack along a first dimension;
a support plate made of a thermally conductive material, the support plate supporting the cell stack on one side of the cell stack in a second dimension orthogonal to the first dimension;
a thermally conductive resin applied on an inner surface of the support plate between the cell stack and the support plate; and
a first fence member disposed along the support plate outside of the thermally conductive resin in the first dimension, the first fence member defining a linear boundary abutting and extending along the inner surface of the support plate in the stacking dimension so as to prevent the thermally conductive resin from leaking out past the linear boundary along the first dimension when the cell stack is placed on the support plate, wherein the linear boundary has a length along the stacking dimension that spans a length of the cell stack along the stacking dimension, and wherein the first fence member has a height along the second dimension that is less than a height of the first busbar frame along the second dimension,
wherein the first busbar frame has an end portion extending in the first dimension inwardly towards a center of the support plate along the inner surface of the support plate, and
wherein the first fence member is located at an end of the end portion of the first busbar frame and is positioned on the inner surface of the support plate.
