Claim 0:
1. A method for manufacturing a flexible battery, comprising:
an injection step of injecting an electrolyte into an opening of an exterior material accommodating an electrode assembly contained therein;
an impregnation step of impregnating the electrode assembly with the electrolyte through a pressure difference inside the exterior material; and
a sealing step of sealing the opening,
wherein a pressure increasing/decreasing process is performed in the impregnation step and one cycle thereof comprises the steps of:
(1) decreasing the pressure inside the exterior material through the injected electrolyte;
(2) maintaining the decreased pressure for a predetermined period of time; and
(3) restoring the pressure inside the exterior material to 700 torr to 780 torr,
wherein the pressure increasing/decreasing process is performed four to eight times with a gradient in the decreased pressure, and
wherein the decreased pressure of the pressure increasing/decreasing process performed in the next turn is performed at a pressure of 40% to 80% of the decreased pressure of the pressure increasing/decreasing process performed in the previous turn.
