Disclosed are a method of manufacturing a flexible thin-film type super-capacitor device and a super-capacitor device manufactured by the same. The flexible thin-film type super-capacitor device comprises a base film which has flexibility; a separator which is interposed between the base films; and an active material which is formed on the base film. Thus, flexibility is given since thickness is very thin while maintaining high electrical conductivity and high binding property. In addition, economic feasibility is high and mass production is possible. Further, it is possible to stably and efficiently contain a highly corrosive material.

An energy storage apparatus suitable for mounting on a printed circuit board using a solder reflow process is disclosed. In some embodiments, the apparatus includes: a sealed housing body (e.g., a lower body with a lid attached thereto) including a positive internal contact and a negative internal contact (e.g., metallic contact pads) disposed within the body and each respectively in electrical communication with a positive external contact and a negative external contact. Each of the external contacts provide electrical communication to the exterior of the body, and may be disposed on an external surface of the body. An electric double layer capacitor (EDLC) (also referred to herein as an “ultracapacitor” or “supercapacitor”) energy storage cell is disposed within a cavity in the body including a stack of alternating electrode layers and electrically insulating separator layers. An electrolyte is disposed within the cavity and wets the electrode layers. A positive lead electrically connects a first group of one or more of the electrode layers to the positive internal contact; and a negative lead electrically connects a second group of one or more of the electrode layers to the negative internal contact.

According to the invention there is provided a component including a supercapacitor and a method of producing same. The component comprises a first (12) and second (14) electrode and a separator structure (16) which separates the two electrodes and contains a liquid or gel electrolyte. The first and second electrode structures are each formed from a composite material (10) which includes electrically conductive fibers and electrochemically active material in a binder matrix and the supercapacitor is formed to be structurally inseparable from the rest of the component. Further, the component forms a structural capacitor. The obtained structural capacitor could be used in aircraft structure to save weight.
