| description | The present invention relates to an electrode capable of preventing a short circuit between an anode and a cathode even when overheat of the battery is caused by laminating a short-circuiting prevention film on a surface of an electrode, a secondary battery using the same, and a method for manufacturing an electrode. An electrode for a secondary battery of the present invention comprises: an electrode current collector; an active material layer formed on the electrode current collector; and a short-circuiting prevention film laminated on the active material layer. The short-circuiting prevention film is formed of a nano-web-type porous membrane formed by integrating nanofiber strands obtained by electrospinning polyacrylonitrile (PAN).
본 발명은 전극의 표면에 단락방지막을 적층하여 전지의 과열이 발생할지라도 단락방지막이 양극과 음극 사이의 단락을 방지할 수 있는 전극 및 이를 이용한 이차전지와 전극의 제조방법에 관한 것이다. 본 발명의 이차전지용 전극은 전극 집전체; 상기 전극 집전체에 형성된 활물질층; 및 상기 활물질층에 적층된 단락방지막;을 포함하며, 상기 단락방지막은 폴리아크릴로니트릴(PAN)을 전기방사하여 얻어지는 나노섬유 스트랜드를 집적하여 형성되는 나노 웹(nano web) 형태의 다공성 멤브레인(Membrane)으로 이루어지는 것을 특징으로 한다. |
