NOVELTY - The battery (100) has two electrode assemblies and a case (120) for accommodating the electrode assemblies. Terminal parts (130, 140) are electrically connected to the electrode assemblies and exposed to outer side of the case. A set of short circuit inducing parts is placed between the first electrode assembly and the case, between the second electrode assembly and the case, and between the electrode assemblies. Another set of short circuit inducing parts is connected to non-coating portions of the electrode assemblies.    USE - Rechargeable secondary battery i.e. lithium ion secondary battery, for use in electric vehicle or a hybrid vehicle. Can also be used for notebook computer and cellular phone.    ADVANTAGE - The second short circuit inducing part is placed between the first and second electrode assemblies and is electrically connected to the second non-coating portions of the second electrode plates of the first and second electrode assemblies, so that the battery does not require the first short circuit inducing part of the secondary battery, thus simplifying manufacturing process of the battery. The battery includes a low-resistance short circuit to be formed within the battery when a nail penetrates the battery from a cap plate to a bottom of the case, or from the bottom of the case to the cap plate, so that the cell allows current from an inner short circuit to efficiently flow to an outside along the electrode short circuit inducing parts when the short circuit inducing parts are arranged together between the first and second electrode assemblies, and an inner short circuit is formed between the electrode assemblies, thus efficiently preventing or preventing overheating and igniting of the battery for improving performance, safety and reliability of the battery.
