Abstract
Provided are a pouch-type flexible film battery and a method of manufacturing the same. The film battery includes a cathode structure including a cathode pouch, a cathode conductive carbon layer, and a cathode layer, an anode structure including an anode pouch, an anode conductive carbon layer, and an anode layer, and a polymer electrolyte layer between the cathode and anode structures. The polymer electrode layer may be a gel-type electrolyte including a cellulose-based polymer.
Claims20
A pouch-type flexible film battery comprising:
- a cathode structure including a cathode pouch, a cathode conductive carbon layer, and a cathode layer;
- an anode structure including an anode pouch, an anode conductive carbon layer, and an anode layer;
- and
- a polymer electrolyte layer between the cathode and anode structures,
- wherein the polymer electrolyte layer is a gel-type electrolyte including a cellulose-based polymer.
A method of manufacturing a pouch-type flexible film battery, the method comprising:
- forming a cathode structure including a cathode conductive carbon layer and a cathode layer sequentially stacked on a first film;
- forming an anode structure including an anode conductive carbon layer and an anode layer sequentially stacked on a second film;
- forming a gel-type electrolyte layer including a cellulose-based polymer on at least one of the cathode and anode structures;
- and
- bonding the cathode and anode structures,
- wherein the bonding of the cathode and anode structures comprises bonding the cathode layer and the anode layer to the gel-type electrolyte layer by using the gel-type electrolyte layer as an adhesive layer while the first and second films are fused by using heat fusion technology.
