METHOD OF FABRICATING CATHODE FOR THIN FILM BATTERY USING LASER, CATHODE FABRICATED THEREBY, AND THIN FILM BATTERY INCLUDING THE SAME

摘要

A method of fabricating a cathode for a thin film battery includes depositing a cathode active material on a substrate, and crystallizing the cathode active material by irradiating laser onto the cathode active material. The cathode active material may be deposited on the substrate at normal temperature, and a light and easily processable polymer substrate may be used by crystallizing the cathode active material at low temperature using laser. A thin film battery including the cathode fabricated by the above method has excellent charging/discharging characteristics such as high discharge capacity.
