Abstract: The present invention relates to a method for cutting a separation membrane for a battery, in which the separation membrane is cut by laser radiation on the separation membrane, wherein the pulse repetition rate of the laser is 10 to 500 kHz; a separation membrane manufactured by the method; and a battery comprising the separation membrane. The present invention, in contrast with physical cutting, has the advantage of being capable of cutting a separation membrane for a battery so as to have a uniform cut surface, which was impossible by conventional physical cutting methods.

Abstract: Disclosed is a separator for an electrochemical device. The separator includes a non-woven web substrate, wherein at least one surface of the non-woven web substrate includes an electrode reactive layer formed by carbonization of the non-woven web substrate from the surface of the non-woven web substrate to a predetermined depth, and the electrode reactive layer is disposed at the outermost side of at least one surface of both surfaces of the separator.

Abstract: A method for manufacturing a glass cliché using laser etching includes a dipping step for dipping a glass cliché, which will be etched, into an etching solution, a patterning step for irradiating laser to the glass cliché dipped in the etching solution to form a pattern therein, and a washing step for washing the patterned glass cliché. This method allows making a cliché with a high aspect ratio and fine line widths in comparison to a conventional cliché 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.
