Abstract

Provided are an electrode wherein a short-circuit preventing film laminated on the surface of the electrode can prevent a short circuit between a cathode and an anode when a battery is overheated; a secondary battery using the electrode; and a method for manufacturing the electrode. The secondary battery electrode includes: an electrode current collector; an active material layer formed on the electrode current collector; and a short-circuit preventing film laminated on the active material layer, wherein the short-circuit preventing film includes a nanoweb type porous membrane which is formed by integrating nanofiber strands obtained by electrospinning polyacrylonitrile (PAN).
