Abstract
(EN)
The present invention relates to an electrode assembly comprising: a basic unit having a first electrode and a second electrode which are stacked in a state where a separator is interposed between the first and second electrodes, wherein the first electrode is stacked on the outermost surface; and a safety unit disposed on the outermost surface of the basic unit, wherein the safety unit comprises a first safety plate disposed on the outermost surface of the basic unit, and a first semiconductor material provided between the basic unit and the first safety plate, wherein the first semiconductor material, while changing from an insulator to a conductor at a first set temperature or above, connects the basic unit and the first safety plate to radiate heat while conducting heat of the basic unit to the first safety plate.
