METHOD FOR MANUFACTURING CATHODE FOR THIN FILM BATTERY USING LASER, CATHODE FOR THIN FILM BATTERY MANUFACTURED THEREBY, AND THIN FILM BATTERY COMPRISING SAME

摘要

A method for forming a cathode for a thin film battery may comprise the steps of: depositing a cathode active material on a substrate; and crystallizing the cathode active material by irradiating a laser on the cathode active material. The cathode active material can be deposited on a substrate at room temperature, and can be crystallized by a laser at low temperatures so that a light and workable polymeric substrate may be used. A thin film battery comprising a cathode manufactured by a method for manufacturing a cathode according to one embodiment of the present invention may have good charging and discharging properties such as high discharge capacity.
