Apparatus and method for removing residual electrolyte from a secondary battery

An apparatus configured to remove a residual electrolyte from a beading part of a case of a cylindrical secondary battery, wherein the case is configured to prevent separation of an electrode assembly, the apparatus comprising:

• an electrolyte absorption member providing part configured to provide an electrolyte absorption member to the case;
• a case moving part 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,
• wherein the case moving part is configured to move the case in a first direction, and
• wherein the absorption member moving part is configured to move the electrolyte absorption member in a second direction that is orthogonal to the first direction.
