Abstract
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.
Claims15
A degassing apparatus for a pouch, the degassing apparatus comprising:
- a mold including a lower mold and an upper mold, the upper mold configured to be positioned above the lower mold, the lower mold configured to contact a bottom surface of a body part of the pouch, and the upper mold configured to press a top surface of the body part when the lower mold contacts the bottom surface of the body part,
- a gas inhaler configured to be inserted into a gas pocket part of the pouch, and
- a cooling member,
- wherein at least one of the lower mold or the upper mold is cooled by the cooling member such that an electrolyte injected into the body part is cooled by the mold when the body part contacts the mold, and wherein the cooling member comprises a Peltier element configured to adjust the cooling according to a temperature and a viscosity of the electrolyte.
A method for degassing a pouch, the method comprising the steps of:
- seating a body part of the pouch on a lower mold;
- forcing an upper mold to descend on the pouch to press the body part seated on the lower mold;
- cooling the body part to lower a temperature of an electrolyte in an electrode assembly of the pouch by a cooling member comprising a Peltier element configured to adjust the cooling according to a temperature and a viscosity of the electrolyte, and
- suctioning a gas from the pouch by inserting a gas inhaler into a gas pocket part of the pouch, the gas pocket part extending from the body part.
