Abstract:
1. A battery module including cylindrical batteries disposed on a plurality of spacers assembled side-by-side, wherein each spacer of the plurality of spacers comprises: battery receiving parts disposed at a top surface and a bottom surface of a frame of each spacer, in a form that surfaces of the battery receiving parts are toward an outside in opposite directions, respectively, the battery receiving parts having semi-cylindrical inner structures corresponding to outer surfaces of the cylindrical batteries; coupling parts disposed at end portions of opposite sides of the battery receiving parts, between the battery receiving part on the top surface and the battery receiving part at the bottom surface, respectively, wherein the coupling parts are engageable with and disengageable from coupling parts of another spacer of the plurality of spacers; and a through-hole formed through a middle part of each spacer such that the cylindrical batteries disposed on the battery receiving parts fluidly communicate with each other via the through-hole, wherein the coupling parts comprise: wherein horizontal passageways are formed by the side grooves in an assembled configuration and function as coolant flow.
