A MANUFACTURING METHOD FOR FLEXIBLE SECONDARY CELL, THE FLEXIBLE SECONDARY CELL MANUFACTURED BY THE SAME

摘要

PURPOSE: A method for manufacturing a flexible secondary cell is provided to improve properties of a secondary battery, to avoid restrictions of processes caused by a flexible printed circuit board, and to improve secondary battery characteristics according to high temperature processing. CONSTITUTION: A method for manufacturing a flexible secondary cell comprises the steps of: laminating a secondary battery device including an electrode material on a sacrificial substrate; crystallizing the electrode material by treating the device at a high temperature; etching the sacrificial substrate of the lower part of the secondary battery device and separating the secondary battery device from the sacrificial substrate; and transferring the separated secondary battery device to a flexible printed circuit board using a transfer layer.
