摘要： A battery module 100 includes a plurality of cells 10 arranged in a grid array. The cells 10 arranged in a row direction are connected together in parallel by a first connecting member 20. The cells 10 arranged in a column direction are connected together such that the cells 10 adjacent to each other in the column direction are connected together in series by a second connecting member 30. When an internal short-circuit occurs in any one of the cells 10, the first connecting member 20 connected to the cell 10 in which the internal short-circuit has occurred is melted by Joule heat generated due to a short-circuit current flowing into the cell 10 in which the internal short-circuit has occurred from the other cells 10 in which no internal short-circuit occurs via the first connecting member 20.

摘要： A safety mechanism for a laminate battery. An exterior case (5) consists of two molded sheets (5a) made of laminate sheets, superposed upon one another, and bonded together around the outer edges. The exterior case has a protrusion (10) that communicates with the interior of the exterior case and protrudes outwardly from one side. A safety vent (13) is made up of an exhaust hole (11) formed in at lease one of the two molded sheets (5a) in the protrusion (10), and a valve element (12) making elastic pressure contact with the edge of the exhaust hole (11) to seal it. The safety mechanism does not operate within the range of internal pressure variation during normal use, but operates reliably at a time point when a predetermined valve operating pressure is reached to release a necessary amount of gas to the outside, this valve operating pressure being within the safe range relative to the pressure resistance of the exterior case (5) made of laminate sheets. Also, the safety vent configuration enables a reduction in production cost.
