The present invention relates to an electrode manufacturing method, an electrode manufactured thereby, and a battery comprising the same, the electrode manufacturing method comprising the steps of: applying an electrode active material onto a collector; and radiating a laser such that the end of an electrode active material layer, which has been obtained by applying the electrode active material, becomes straight, thereby removing the electrode active material. The present invention is advantageous in that the difference in area between active materials applied to the positive and negative electrodes, respectively, is minimized, thereby increasing the capacity and improving the stability of the battery.

A method for high resolution ink-jet print using a pre-patterned substrate employs an ink-jet printing device including an ink-jet head for discharging conductive ink droplets and a driving stage for supporting a substrate to which the conductive ink droplets are hit, to draw a fine line width pattern on the substrate. The method includes (A) forming a stripe pattern with repeated stripes on a substrate surface on which a fine line width pattern will be formed, thereby preparing a pre-patterned substrate; (B) loading the substrate to the ink-jet printing device; and (C) injecting conductive ink droplets to a substrate region where the stripe pattern is formed. An equivalent interval (d) of the stripe pattern and a fine line width (D) of the drawn fine line width pattern satisfy a relation of d&#x3c;&#x3c;D, and the hit ink droplets are flowed in an anisotropic form within the region.

A preparation method of an electroconductive copper patterning layer includes (Step 1) preparing a dispersion solution of copper-based particles selected from the group consisting of copper particles, copper oxide particles, and their mixtures; (Step 2) forming a copper-based particle patterning layer by printing or filling the dispersion solution of copper-based particles to a substrate into a predetermined shape; and (Step 3) irradiating laser to the copper-based particle patterning layer to burn and interconnect the copper-based particles contained in the copper-based particle patterning layer. This preparation method burns a copper-based particle patterning layer with a strong energy within a short time by using laser. Thus, it is possible to obtain a copper patterning layer that is hardly oxidized even in the atmosphere, so a copper patterning layer with excellent electric conductivity is formed.
