Pouch type lithium secondary battery and method of fabricating the same

A method of fabricating a pouch type lithium secondary battery, comprising:

• preparing a pouch including a front plate and a rear plate folded along a folding line, the rear plate having an electrode assembly storing space;
• storing an electrode assembly in the electrode assembly storing space, the electrode assembly including a first electrode plate connected to a first electrode tap, a second electrode plate connected to a second electrode tap, and a separator interposed between the first electrode plate and the second electrode plate;
• forming a pouch bare cell by sealing edges of the front plate and the rear plate of the pouch;
• and
• wrapping the electrode assembly with the pouch by winding around the electrode assembly storing space with a part of the pouch bare cell to provide a shape of a pouch exterior.

A method of fabricating a pouch type lithium secondary battery, comprising:

• preparing a pouch member including a rear plate having an electrode assembly storing space and a front plate that covers the electrode assembly storing space;
• storing an electrode assembly in the electrode assembly storing space, the electrode assembly including a first electrode plate connected to a first electrode tap, a second electrode plate connected to a second electrode tap, and a separator interposed between the first and second electrode plates;
• forming a pouch bare cell by arranging the front plate and the rear plate such that the front plate covers the electrode assembly storing space and sealing the front plate and the rear plate at a circumferential area around the electrode assembly storing space to partially bond the front plate and the rear plate with each other;
• and
• wrapping the pouch bare cell by entirely winding around the electrode assembly storing space with at least a part of the circumferential area.

A method of fabricating a pouch type lithium secondary battery, comprising:

• preparing a pouch member having a front plate and a rear plate having different areas, the rear plate having an electrode assembly storing space formed in a part of the rear plate, and the front plate covering the electrode assembly storing space;
• storing an electrode assembly in the electrode assembly storing space, the electrode assembly including a first electrode plate to which a first electrode tap is attached, a second electrode plate to which a second electrode tap is attached, and a separator interposed between the first electrode plate and the second electrode plate;
• forming a pouch bare cell by arranging the front plate and the rear plate such that the front plate covers the electrode assembly storing space and sealing the front and rear plates at a circumferential area around the electrode assembly storing space to partially bond the front plate and the rear plate with each other;
• and
• wrapping the pouch bare cell by winding around the electrode assembly storing space with a part of the circumferential area such that a unsealed part of the circumferential area winds around at least a part of the electrode assembly storing space.
