Abstract:
1. A secondary battery module, comprising: a plurality of secondary batteries, each of the secondary batteries including an electrode assembly, a case accommodating the electrode assembly, an electrode terminal electrically connected to the electrode assembly, and a first short-circuit area electrically connected to the electrode terminal, the first short-circuit area including: (a) a surface to protrude outwardly relative to the case when an internal pressure of the case exceeds a preset pressure, and (b) a pipe to direct the internal pressure toward the surface; a connector electrically connecting electrode terminals of adjacent ones of the secondary batteries; and a second short-circuit area overlapping the first short-circuit area of at least one of the plurality of secondary batteries, the second short-circuit area contacting the first short-circuit area when the first short-circuit member protrudes outwardly relative to the case.
