Abstract

The present specification discloses a current collector. The current collector comprises a polymer layer exhibiting a so-called PTC (Positive Temperature Coefficient) effect. The polymer layer exhibits the PTC effect very precisely responding to a temperature and an external voltage. The polymer layer can quickly switch between a state exhibiting excellent electrical properties such as low resistance and a state exhibiting insulator properties due to increased resistance at a necessary time. The current collector is applied to various electronic/electrical devices, whereby in a normal state, it does not affect driving of the devices, and the like through excellent electrical properties, and in an abnormal state, it is possible to ensure stability through a rapid resistance increase.
