ELECTRODE FOR SECONDARY BATTERY, SECONDARY BATTERY COMPRISING SAME, AND CABLE-TYPE SECONDARY BATTERY

摘要

The present invention relates to an electrode for a secondary battery, a secondary battery comprising same, and a cable-type secondary battery and, more specifically, to an electrode for a secondary battery, a secondary battery comprising same, and a cable-type secondary battery, the electrode comprising: a current collector; an electrode active material layer formed on at least one surface or the entire outer surface of the current collector; a conductive material coating layer which is formed on the upper surface of the electrode active material layer and comprises a conductive material and a first polymer binder; and a porous coating layer which is formed on the upper surface of the conductive material coating layer and comprises a second polymer binder.
