    Abstract: PURPOSE: A production method of a negative electrode is provided to provide the negative electrode which has excellent cycle performance under the high-current and superior energy storage density per the unit volume. CONSTITUTION: A manufacturing method of a current collector in which a micro-polymer is patterned comprises the following steps: producing a polymer solution; coating the polymer solution on the surface of the current collector; producing a mixed solvent by diluting a solvent with a non-solvent; and processing the mixed solvent on the substrate in which the polymer solution is coated, and drying the result. A production method of a negative electrode comprises the following steps: plating electroless copper on the upper side of the current collector in which the micro-polymer is patterned; removing the polymer pattern, and forming an electrode active material on the current collector using a chemical deposition or physical deposition method; and reforming the surface of the electrode active material.
