Claim of US Patent No. 9,252,405

1. A secondary battery comprising:
a first electrode assembly;
a second electrode assembly;
a case accommodating the first and second electrode assemblies;
a first terminal part electrically connected to the first and second electrode assemblies, and exposed to an outside of the
case, the first terminal part having a first polarity;

a second terminal part electrically connected to the first and second electrode assemblies, the second terminal, part having
a second polarity opposite the first polarity; and

a plurality of short circuit inducing members comprising a plurality of first short circuit inducing members electrically
connected to the first terminal part and a second short circuit inducing member electrically connected to the second terminal
part, a first one of the first short circuit inducing members being between the first electrode assembly and the case, a second
one of the first short circuit inducing members being between the second electrode assembly and the case, and the second short
circuit inducing member being between the first electrode assembly and the second electrode assembly,

wherein the first one of the first short circuit inducing members, the first electrode assembly, the second short circuit
inducing member, and the second electrode assembly are sequentially arranged along a line of penetration extending through
a side part of the case, and

wherein, in a non-short-circuited state between the first and second terminal parts, each of the plurality of first short
circuit inducing members is electrically connected to the first terminal part, and the second short circuit inducing member
is electrically connected to the second terminal part.
