Abstract

The present invention provides an electrode for a secondary battery, more specifically an electrode for a secondary battery, comprising a current collector; an electrode active material layer formed on at least one surface or the whole outer surface of the current collector; a conductive material-coating layer formed on the top surface of the electrode active material layer and comprising a conductive material and a first polymer binder; and a porous coating layer formed on the top surface of the conductive material-coating layer and comprising a second polymer binder. Also, the present invention provides a secondary battery and a cable-type secondary battery comprising the electrode.
