ELECTRODE, A METHOD FOR PREPARING THE SAME, ELECTRODE PREPARED USING THE SAME AND SECONDARY BATTERY CONTAINING THE SAME

摘要

The present invention relates to an electrode, a producing method thereof, an electrode produced thereby, and a secondary battery comprising the same. The electrode comprises: an electrode current collector; a metal nano-wire formed on a surface of the electrode current collector; and a conductive layer covering an external portion of the metal nano-wire, and has an air gap between the metal nano-wire and the conductive layer, wherein the metal nano-wire and the conductive layer are spaced so as not to come in direct contact with each other.
