Title: ELECTRODE, SECONDARY BATTERY USING SAME, AND MANUFACTURING METHOD FOR ELECTRODE
Abstract:
The present invention relates to an electrode, a secondary battery using the same, and a method for manufacturing the electrode, wherein a short-circuiting preventing layer made of a porous polymer fiber web of a heat-resistant polymer fiber is formed on the surface of the electrode with a high bonding force, so that the short-circuiting preventing layer can prevent short-circuiting between a positive electrode and a negative electrode even when a battery overheats. The electrode of the present invention comprises: an electrode collector; an active material layer formed on the electrode collector; and a short-circuiting preventing layer formed on the active material layer, wherein the short-circuiting preventing layer includes a porous polymer fiber web including microfine fibers of a heat-resistant polymer material accumulated therein and thus having a plurality of pores.
