Abstract
Provided are an electrode capable of preventing separation of a short-circuit prevention layer since the short-circuit prevention layer, which is made of a heat-resistant polymer fiber, can be attached with high binding force when formed on the surface of the electrode, in the case that an active material layer includes a predetermined amount of polyvinylidene fluoride (PVdF) as a binder; a secondary battery using the same; and a method of manufacturing the electrode. The electrode includes: an electrode current collector; an active material layer formed on the electrode current collector; and a short-circuit prevention layer formed on the active material layer, wherein the short-circuit prevention layer includes a porous polymer fiber web having a plurality of pores through accumulation of ultrafine fibers of a heat-resistant polymer material, and the active material layer includes PVdF as a binder.
