| 摘要 |
The present invention relates to an electrode assembly for a secondary battery and a secondary battery using the same, in which a porous conductive metal layer is formed on particle surfaces of an anode active material layer and/or a cathode active material layer by a deposition method, thereby forming a metallic network formed by a porous conductive metal layer as well as an electronic conduction network formed by a conductive agent mixed with an active material inside the electrode, so that the electrode assembly can improve electrical conductivity, ion conductivity, and the capacity of the battery. The electrode assembly for the secondary battery of the present invention includes: an anode having an anode current collector and an anode active material layer formed on at least one surface of the anode current collector; a cathode having a cathode current collector and a cathode active material layer formed on at least one surface of the cathode current collector; a porous separation film formed between the cathode and the anode; and a porous conductive metal layer formed on at least one surface of the cathode active material layer and the anode active material layer, the porous conductive metal layer having a plurality of pores to allow the movement of lithium ions. |
