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 manufacturing a glass plate using laser etching includes a dipping step for dipping a glass plate, which will be etched, into an etching solution, a patterning step for irradiating laser to the glass plate dipped in the etching solution to form a pattern therein, and a washing step for washing the patterned glass plate. This method allows making a plate with a high aspect ratio and fine line widths in comparison to a conventional plate manufacturing method using photoresist for etching, and also ensures more efficient energy consumption and higher etching efficiency rather than an etching method using laser only.

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.
