Disclose herein is a degassing apparatus for a pouch including a body part. The degassing apparatus can include a lower mold placed on a bottom surface of the body part, an upper mold configured to press a top surface of the body part placed on the lower mold, and a cooling member. At least one of the lower mold or the upper mold is cooled by the cooling member to cool an electrolyte injected into the body part when the body part contacts the lower or upper molds. A method for degassing a pouch can include seating a body part of the pouch on a lower mold, pressing the pouch with an upper mold, cooling a body part to lower the temperature of an electrolyte in an electrode assembly of the pouch, and suctioning a gas by inserting a gas inhaler into a gas pocket part.

Degassing apparatus and degassing method

The present technology relates to an electrode manufacturing method, an electrode manufactured by the method, and a secondary battery comprising same, the electrode manufacturing method comprising a cleaning step performed by laser irradiation, in lines corresponding to each other in a direction perpendicular to an electrode current collector, onto a top-coated electrode mixture layer and a back-coated electrode mixture layer of the electrode current collector, and may prevent a mismatch of the electrode mixture layers and may significantly reduce the degree of sliding occurrence at the boundary region.

Electrode manufacturing method comprising cleaning step using laser, electrode manufactured by method, and secondary battery comprising same

The present invention relates to an electrolyte detection device. The electrolyte detection device comprises: a contamination detection plate configured to contact any one surface of a secondary battery, in which an opening is provided; first and second conductors provided to be spaced apart from each other so that current does not flow on a surface of the contamination detection plate, the first and second conductors being electrically connected to each other by an electrolyte leaking from the opening of the secondary battery; a power member comprising a positive electrode connected to the first conductor and a negative electrode connected to the second conductor; and a contamination detection member configured to detect whether the electrolyte leaks through the current generated when the first conductor and the second conductor are electrically connected to each other.
