Title:
FLEXIBLE BATTERY MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/240468
Kind Code:
A1
Abstract:
A flexible battery manufacturing method is provided. A flexible battery manufacturing method according to an embodiment of the present invention comprises: an injection step of injecting an electrolyte into an opening of a sheath material having an electrode assembly contained therein; an impregnation step of impregnating the electrode assembly with the electrolyte through a change in the pressure inside the sheath material; and a sealing step of sealing the opening. In the impregnation step, a pressure increasing/decreasing process is performed, wherein one cycle of the pressure increasing/decreasing process comprises the steps of: (1) decreasing the pressure inside the sheath material through the injected electrolyte; (2) maintaining the decreased pressure for a predetermined period of time; and (3) restoring the pressure inside the sheath material to 700-780Torr. Accordingly, the flexible battery manufacturing method according to the present invention is advantageous in that, since the electrode assembly provided in the battery can be fully impregnated with the electrolyte, no spot occurs on the surface of the negative electrode filled with the electrolyte. In addition, a flexible battery manufactured by the flexible battery manufacturing method according to the present invention can prevent or minimize degradation of physical characteristics that the battery is required to exhibit, even if repeated bending occurs.
