Abstract
The present disclosure relates to a method for manufacturing a secondary battery including a gel polymer electrolyte and a secondary battery obtained thereby. The method can inhibit thermal crosslinking of a gel polymer electrolyte during the wetting with an electrolyte, and facilitate thermal crosslinking after the wetting with an electrolyte is finished. In addition, the method can increase uniformity of thermal crosslinking by controlling the oxygen content in a cell.
