| 摘要 |
The present invention relates to a method for manufacturing a polymer battery, comprising: a first hot press step of applying heat and pressure to a pouch to push air bubbles in the pouch to a gas pocket portion in the pouch; a degassing step of removing, in a vacuum state, gas generated in the pouch during a charging and discharging process for an electrode assembly in the pouch; and a sealing step of sealing an opening portion of the pouch after the degassing step. According to the present invention, the first hot press step is performed before the degassing step, through gas expansion in the pouch, to facilitate the discharge of gas and an electrolyte solution, and push air bubbles to the gas pocket portion in the pouch. Therefore bubble defects can be ameliorated. |
