Abstract
A flexible lithium battery includes a flexible pouch and two conductive tabs. The flexible pouch has an accommodating space and a being sealed side, and the two conductive tabs are inserted in the being sealed side and extended to the accommodating space. The being sealed side includes a first sealing area and a second sealing area, the first sealing area and the second sealing area are sealed to form a side seal through a combination means. The first sealing area has a first binding force, and the second sealing area has a second binding force. The second binding force is smaller than the first binding force, and gas accumulated in the accommodating space is discharged from the second sealing area.

Structures of a lithium battery cell, comprising a flexible pouch and two conductive tabs, the flexible pouch having an accommodating space and a being sealed side located at a periphery of the accommodating space;
- the two conductive tabs being inserted in the being sealed side and extended to the accommodating space, the being sealed side including a first sealing area and a second sealing area, the first sealing area and the second sealing area being sealed to form a side seal through a combination means;
- the first sealing area having a first binding force, and the second sealing area having a second binding force, wherein the second binding force is smaller than the first binding force, and gas accumulated in the accommodating space is discharged from the second sealing area.
A manufacturing process of a lithium battery cell, comprising:
- a) providing a flexible pouch and two conductive tabs;
- b) folding the flexible pouch to form a bag body with a being sealed side, the being sealed side of the bag body including a first sealing area and a second sealing area;
- c) inserting the two conductive tabs in the being sealed side;
- and
- d) sealing the being sealed side with a combination means, and making a binding force of the seconding area smaller than that of the first sealing area.
