Abstract
A method for manufacturing a gel polymer electrolyte battery, the method comprising two steps of pressurization carried out before and after a formation step, is provided. The method provides a gel polymer electrolyte battery having a small gap between a separator and an electrode, high binding force, reduced thickness, improved shape stability and stiffness, and thus provides the gel polymer electrolyte battery having increased initial capacity, reduced initial resistance, and improved characteristics, such as cycle characteristics, high-temperature safety, overcharge safety and penetration safety.
