1. A flexible battery, comprising:
an electrode assembly having:
at least one unit cell including a pair of electrode plates having different polarities, and a separator interposed between the respective electrode plates,
wherein at least one surface of each of the pair of electrode plates is coated with an electrode mixture; and
electrode tabs that are protruding parts of the respective electrode plates,
wherein the electrode tabs include electrode lead connection tabs and electrode parallel connection tabs;
a pair of electrode leads connected to the electrode lead connection tabs,
the electrode parallel connection tab is formed on each of a plurality of electrode plates included in the electrode assembly, and is formed at one end of the electrode assembly to electrically connect at least two electrode plates having a same polarity among the plurality of electrode plates, and
all of the electrode lead connection tabs are connected to the electrode lead and are formed on at least one electrode plate among the plurality of electrode plates, and are formed at an end opposite to the one end at which the electrode parallel connection tab is formed, and
wherein a tab-lead joint portion at which the electrode lead connection tab and the electrode lead are connected together on only the protruding part of a respective one of the electrode plates is inserted into the electrode assembly such that the electrode lead is not overlapped by the electrode parallel connection tab.
