Abstract

The present invention relates to an electrode structure for a secondary battery comprising a potential sheath capable of suppressing a side reaction between an electrode and an electrolyte through electric potential control, and a method for manufacturing the same. The electrode structure for the secondary battery according to the present invention uses the electric potential control so that an unstable SEI layer, which causes decrease in cycle characteristic and capacity of an anode material, occurs only on the surface of a potential sheath without occurring on the surface of the anode active material, thereby being capable of completely solving the problems of the existing nanostructured electrode. The electrode structure of the present invention exhibits very excellent cycle performance that is difficult to predict from the conventional nanowire electrode structure by virtue of a synergistic effect of the potential sheath and the nanowire anode active material, and has an effect that is stable upon charging and discharging with high rate and can exert stable performance even if small cracks occur on the potential sheath.
