Apparatus and method for removing residual electrolyte from a secondary battery

Abstract

An apparatus configured to remove a residual electrolyte from a beading part of a case of a cylindrical secondary battery, the case being configured to prevent or reduce separation of an electrode assembly. The apparatus includes an electrolyte absorption member providing part configured to provide an electrolyte absorption member to the case, a case moving part for coupling to the electrode assembly, wherein the case moving part is configured to move the case after the case has received an injection of an electrolyte, and an absorption member moving part configured to move an area of the electrolyte absorption member onto the beading part of the case to absorb at least some of the residual electrolyte from the beading part.
