Spacer for production of battery pack

Abstract

Disclosed herein is a spacer for production of a battery pack using cylindrical batteries as unit cells, wherein the spacer is constructed in the form of a rectangular frame, the spacer is provided at opposite side surfaces (opposite faces) of the rectangular frame with a plurality of battery receiving parts having a circumference-type inner surface structure that partially covers the outer surfaces of the cylindrical batteries, each battery receiving part has a horizontal through-hole, which extends between the opposite side surfaces of the frame, and a pair of battery receiving parts (a unit receiving part) formed at the opposite side surfaces of the frame is connected with another adjacent unit receiving part via structures that can be easily cut. Consequently, the spacer according to the present invention has the effect of allowing the production of a structurally stable battery pack using the minimized number of parts, reducing the number of processes, thereby lowering the costs of products, and preventing the occurrence of short circuits between unit cells during the assembly or the use of the battery pack. In addition, the spacer according to the present invention can be cut into various appropriate sizes, as occasion demands. Consequently, the spacer according to. the present invention has the effect of easily adjusting the capacity and output of a battery pack and effectively removing heat generated from unit cells during the charge and discharge of the unit cells.
